Introduction
1
This Administrator’s Guide describes both the PGP Universal Server ™ and client
software. It tells you how to get them up and running on your network, how to
configure them, and how to maintain them. This section provides a high-level
overview of PGP Universal Server.
What is PGP Universal Server?
PGP Universal Server is a single console for managing the applications that
provide email, disk, and network file encryption.
PGP Universal Server with PGP Universal Gateway Email gives you secure
messaging: it transparently protects your enterprise messages with little or no
user interaction.
The PGP Universal Server also replaces the PGP Keyserver product with a builtin keyserver, and the PGP Admin product with PGP Desktop configuration and
deployment capabilities.
PGP Universal Server automatically creates and maintains a Self-Managing
Security Architecture (SMSA) by monitoring authenticated users and their email
traffic. You can also send protected messages to addresses that are not part of
the SMSA. The PGP Universal Server encrypts, decrypts, signs, and verifies
messages automatically, providing strong security through policies you control.
PGP Universal Satellite, a client-side feature of PGP Universal Server, extends
PGP security for email messages all the way to the computer of the email user,
it allows external users to become part of the SMSA, and it gives end users the
option to create and manage their keys on their own computer (if allowed by the
PGP administrator).
PGP Desktop, a client product, is created and managed through PGP Universal
Server policy. It creates PGP keypairs and can manage user keypairs as well as
store the public keys of others. It encrypts user email and instant messaging
(IM). It can encrypt entire or partial hard drives. It also enables secure file
sharing with others over a network.
15
PGP Universal Server Introduction
PGP Universal Server Product Family
PGP Universal Server functions as a management console for a variety of
encryption solutions. You can purchase any of the PGP Desktop applications or
bundles and use PGP Universal Server to create and manage client installations.
You can also purchase a license that enables PGP Gateway Email to encrypt
email in the mailstream.
The PGP Universal Server can manage any combination of PGP encryption
applications. PGP encryption applications are:
PGP Universal Gateway Email provides automatic email encryption in the
gateway, based on centralized mail policy. This product requires
administration by the PGP Universal Server.
PGP Desktop Email provides encryption at the desktop for mail, files, and
AOL Instant Messenger traffic. This product can be managed by the PGP
Universal Server.
PGP Whole Disk Encryption provides encryption at the desktop for an
entire disk. This product can be managed by the PGP Universal Server.
PGP NetShare provides transparent file encryption and sharing among
desktops. This product can be managed by the PGP Universal Server.
Who Should Read This Guide
This Administrator’s Guide is for the person or persons who implement and
maintain your organization’s PGP Universal Server environment. These are the
PGP Universal Server administrators.
This guide is also intended for anyone else who wants to learn about how PGP
Universal Server works.
Common Criteria Environments
To be Common Criteria compliant, please refer to the best practices shown in
PGP Universal Server 2.9 Common Criteria Supplemental. Note that these best
practices supersede recommendations made elsewhere in this and other
documentation.
16
PGP Universal Server Introduction
Improvements in this Version of PGP Universal Server
This release of PGP Universal Server introduces the following new and
improved features:
Verified Directory users, and devices are now called consumers.
Consumers are sorted into groups manually, by user type, or by matching
consumer attributes to domains, dictionary entries or through LDAP values.
Group membership determines which policy consumers receive.
Expanded directory synchronization: The integrated directory
synchronization feature now connects to multiple LDAP directories.
Previous versions of PGP Universal Server could only connect to one
corporate directory at a time.
Managed PGP Mobile: PGP Universal Server now manages client policy
for PGP Mobile installations.
Operating system change: The new CentOS operating system improves
scalability and reliability, and supports a wider variety of hardware.
RSA SecurID support for administrator authentication: PGP Universal
Server now supports two-factor authentication using RSA SecurID. This
meets strong authentication requirements for environments with higher
security needs, and is compatible with existing RSA SecurID deployments.
PGP Keys
Key Management Server (KMS): The new key management feature
provides new and expanded key management capabilities for PGP
products. Key policy changes are now immediately enforced. KMS allows
management of asymmetric and symmetric keys. The API and SDK provide
key management functionality to non-PGP applications.
Server Key Mode offline use: The client can now store the SKM private
key, encrypted to a random passphrase, so users can read email offline.
PGP Messaging
ADK archival output: Administrators can archive end-to-end encrypted
email messages by decrypting the messages on PGP Universal Server
using the ADK, and sending the decrypted messages to an archive server.
Encrypted email messages are then searchable, making possible
compliance with regulatory mandates and requirements for message
retention, mail server data management, and legal discovery support.
17
PGP Universal Server Introduction
Recursive encoding: Provides an additional layer of protection to email
messages that have been partially protected and to email messages that
have been signed. Supports an additional layer of encoding if the initial layer
is not complete.
Clustering
New clustering functionality: Cluster members now interact with each
other as peers, replacing the previous Primary/Secondaries model. Every
server in a cluster can serve all types of requests, and any server can
initiate persistent changes. The new cluster model also permits up to 20
nodes in a cluster.
Using the PGP Universal Server with the Command Line
Using the PGP Universal Server command line for read-only access (such as to
view settings, services, logs, processes, disk space, query the database, etc) is
supported. However, performing configuration modifications via the command
line voids your PGP Support agreement unless these procedures are followed.
Any changes made to the PGP Universal Server via the command line must be:
Symbols
Authorized in writing by PGP Support.
Implemented by a PGP Partner, reseller or internal employee who is
certified in the PGP Advanced Administration and Deployment Training.
Summarized and documented in a text file in /etc/pso on the PGP Universal
Server itself.
Changes made through the command line might not persist through reboots and
might be incompatible with future releases. PGP Support can require reverting
any custom configurations on the PGP Universal Server back to a default state
when troubleshooting new issues.
Notes, Cautions, and Warnings are used in the following ways.
Note: Notes are extra, but important, information. A Note calls your attention
to important aspects of the product. You can use the product better if you
read the Notes.
Caution: Cautions indicate the possibility of loss of data or a minor security
breach. A Caution tells you about a situation where problems can occur
unless precautions are taken. Pay attention to Cautions.
18
PGP Universal Server Introduction
Warning: Warnings indicate the possibility of significant data loss or a major
security breach. A Warning means serious problems will occur unless you
take the appropriate action. Please take Warnings very seriously.

The Big Picture
2
This chapter describes some important terms and concepts and gives you a
high-level overview of the things you need to do to set up and maintain your
PGP Universal Server environment.
Important Terms
The following sections define important terms you will encounter throughout
the PGP Universal Server and this documentation.
PGP Products
PGP Universal Server: A device you add to your network that provides
secure messaging with little or no user interaction. The PGP Universal
Server automatically creates and maintains a security architecture by
monitoring authenticated users and their email traffic. You can also send
protected messages to addresses that are not part of the security
architecture.
PGP Global Directory: A free, public keyserver hosted by PGP Corporation.
The PGP Global Directory provides quick and easy access to the universe of
PGP keys. It uses next-generation keyserver technology that queries the
email address on a key (to verify that the owner of the email address wants
their key posted) and lets users manage their own keys. Using the PGP
Global Directory significantly enhances your chances of finding a valid public
key of someone to whom you want to send secured messages.
PGP Universal Satellite: The PGP Universal Satellite software resides on
the computer of the email user. It allows email to be encrypted end to end,
all the way to and from the desktop (for both internal and external users).
Using PGP Universal Satellite is one of the ways for external users to
participate in the SMSA. It also allows users the option of controlling their
keys on their local computers (if allowed by the administrator).
PGP Desktop: A client software tool that uses cryptography to protect your
data against unauthorized access. PGP Desktop is available for Mac OS X
and Windows.
PGP Whole Disk Encryption: Whole Disk Encryption is a feature of PGP
Desktop that encrypts your entire hard drive or partition (on Windows
systems), including your boot record, thus protecting all your files when you
are not using them.
21
PGP Universal Server The Big Picture
PGP NetShare: A feature of PGP Desktop for Windows with which you can
securely and transparently share files and folders among selected
individuals. PGP NetShare users can protect their files and folders simply by
placing them within a folder that is designated as protected.
PGP Virtual Disk: PGP Virtual Disk volumes are a feature of PGP Desktop
that let you use part of your hard drive space as an encrypted virtual disk.
You can protect a PGP Virtual Disk volume with a key or a passphrase. You
can also create additional users for a volume, so that people you authorize
can also access the volume.
PGP Zip: A feature of PGP Desktop that lets you put any combination of
files and folders into a single encrypted, compressed package for
convenient transport or backup. You can encrypt a PGP Zip archive to a PGP
key or to a passphrase.
PGP Universal Web Messenger: The PGP Universal Web Messenger
service allows an external user to securely read a message from an internal
user before the external user has a relationship with the SMSA. If PGP
Universal Web Messenger is available via mail policy for a user and the
recipient’s key cannot be found, the message is stored on the PGP
Universal Server and an unprotected message is sent to the recipient. The
unprotected message includes a link to the original message, held on the
PGP Universal Server. The recipient must create a passphrase, and then
can access his encrypted messages stored on PGP Universal Server.
PDF Messenger: PDF Messenger enables sending encrypted PDF
messages to external users who do not have a relationship with the SMSA.
In the normal mode, as with PGP Universal Web Messenger, the user
receives a message with a link to the encrypted message location and uses
a PGP Universal Web Messenger passphrase to access the message. PDF
Messenger also provides Certified Delivery, which encrypts the message to
a one-time passphrase, and creates and logs a delivery receipt when the
user retrieves the passphrase.
PGP Universal Server Concepts
keys.<domain> convention: PGP Universal Server automatically looks for
valid public keys for email recipients at a special hostname, if no valid public
key is found locally to secure a message. This hostname is keys.<domain>
(where <domain> is the email domain of the recipient). For example,
Example Corporation’s externally visible PGP Universal Server is named
keys.example.com.
PGP Corporation strongly recommends you name your externally visible
PGP Universal Server according to this convention because it allows other
PGP Universal Servers to easily find valid public keys for email recipients in
your domain.
For more information, see Naming your PGP Universal Server (on page
22
37).
PGP Universal Server The Big Picture
Security Architecture: Behind the scenes, the PGP Universal Server
creates and manages its own security architecture for the users whose
email domain it is securing. Because the security architecture is created
and managed automatically, we call this a self-managing security
architecture (SMSA).
PGP Universal Server Features
Administrative Interface: Each PGP Universal Server is controlled via a
Web-based administrative interface. The administrative interface gives you
control over PGP Universal Server. While many settings are initially
established using the web-based Setup Assistant, all settings of a PGP
Universal Server can be controlled via the administrative interface.
Backup and Restore: Because full backups of the data stored on your PGP
Universal Server are critical in a natural disaster or other unanticipated loss
of data or hardware, you can schedule automatic backups of your PGP
Universal Server data or manually perform a backup.
You can fully restore a PGP Universal Server from a backup. In the event of
a minor problem, you can restore the PGP Universal Server to any saved
backup. In the event that a PGP Universal Server is no longer usable, you
can restore its data from a backup onto a new PGP Universal Server during
initial setup of the new PGP Universal Server using the Setup Assistant. All
backups are encrypted to the Organization Key and can be stored securely
off the PGP Universal Server.
Cluster: When you have two or more PGP Universal Servers in your
network, you configure them to synchronize with each other; this is called a
“cluster.”
Dictionary: Dictionaries are lists of terms to be matched. The dictionaries
work with mail policy to allow you to define content lists that can trigger
rules.
Directory Synchronization: If you have LDAP directories in your
organization, your PGP Universal Server can be synchronized with the
directories. The PGP Universal Server automatically imports user
information from the directories when users send and receive email; it also
creates internal user accounts for them, including adding and using X.509
certificates if they are contained in the LDAP directories.
Ignition Keys: You can protect the contents of a PGP Universal Server,
even if the hardware is stolen, by requiring the use of a hardware token or a
software passphrase, or both, on start.
Keyserver: Each PGP Universal Server includes an integrated keyserver
populated with the public keys of your internal users. When an external
user sends a message to an internal user, the external PGP Universal
Server goes to the keyserver to find the public key of the recipient to use to
secure the message. The PGP Universal Server administrator can enable or
disable the service, and control access to it via the administrative interface.
23
PGP Universal Server The Big Picture
Learn Mode: When you finish configuring a PGP Universal Server using the
Setup Assistant, it begins in Learn Mode, where the PGP Universal Server
sends messages through mail policy without taking any action on the
messages, and does not encrypt or sign any messages.
Learn Mode gives the PGP Universal Server a chance to build its SMSA
(creating keys for authenticated users, for example) so that when when
Learn Mode is turned off, the PGP Universal Server can immediately begin
securing messages. It is also an excellent way for administrators to learn
about the product.
You should check the logs of the PGP Universal Server while it is in Learn
Mode to see what it would be doing to email traffic if it were live on your
network. You can make changes to the PGP Universal Server’s policies
while it is in Learn Mode until things are working as expected.
Mail Policy: The PGP Universal Server processes email messages based
on the policies you establish. Mail policy applies to inbound and outbound
email for both PGP Universal Server traffic and email processed by PGP
client software. Mail policy consists of multiple policy chains, comprised of
sequential mail processing rules.
Organization Certificate: You must create or obtain an Organization
Certificate to enable S/MIME support by PGP Universal Server. The
Organization Certificate signs all X.509 certificates the server creates.
Organization Key: The Setup Assistant automatically creates an
Organization Key (actually a keypair) when it configures a PGP Universal
Server. The Organization Key is used to sign all PGP keys the PGP Universal
Server creates and to encrypt PGP Universal Server backups.
Caution: It is extremely important to back up your Organization Key: all
keys the PGP Universal Server creates are signed by the Organization Key,
and all backups are encrypted to the Organization Key. If you lose your
Organization Key and have not backed it up, the signatures on those keys
are meaningless and you cannot restore from backups encrypted to the
Organization Key.
PGP Verified Directory: The PGP Verified Directory supplements the
internal keyserver by letting internal and external users manage the
publishing of their own public keys. The PGP Verified Directory also serves
as a replacement for the PGP Keyserver product. The PGP Verified
Directory uses next-generation keyserver technology to ensure that the
keys in the directory can be trusted.
Server Placement: A PGP Universal Server can be placed in one of two
locations in your network to process email.
With an internal placement, the PGP Universal Server logically sits between
your email users and your mail server. It encrypts and signs outgoing SMTP
email and decrypts and verifies incoming mail being picked up by email
clients using POP or IMAP. Email stored on your mail server is stored
secured (encrypted).
24
PGP Universal Server The Big Picture
With a gateway placement, the PGP Universal Server logically sits between
your mail server and the Internet. It encrypts and signs outgoing SMTP
email and decrypts and verifies incoming SMTP email. Email stored on your
mail server is stored unsecured.
For more information, see Configuring Mail Proxies (on page
PGP Universal Server Installation Guide.
Setup Assistant: When you attempt to log in for the first time to the
administrative interface of a PGP Universal Server, the Setup Assistant
takes you through the configuration of that PGP Universal Server.
PGP Universal Server User Types
Administrators: Any user who manages the PGP Universal Server and its
security configuration from inside the internal network.
Only administrators are allowed to access the administrative interface that
controls PGP Universal Server. A PGP Universal Server supports multiple
administrators, each of which can be assigned a different authority: from
read-only access to full control over every feature and function.
Consumers: Internal, external, and Verified Directory users, and devices.
External Users: External users are email users from other domains
(domains not being managed by your PGP Universal Server) who have
been added to the SMSA.
Internal Users: Internal users are email users from the domains being
managed by your PGP Universal Server.
171) and the
PGP Universal Server allows you to manage PGP Desktop deployments
to your internal users. The administrator can control which PGP Desktop
features are automatically implemented at install, and establish and
update mail security policy for PGP Desktop users that those users
cannot override (except on the side of being more secure).
PGP Verified Directory Users: Internal and external users who have
submitted their public keys to the PGP Verified Directory, a Webaccessible keyserver.
Devices: Managed devices, WDE computers, and WDE disks.
Managed devices are arbitrary objects whose keys are managed by
PGP Universal Server. WDE computers, and WDE disks are devices
that are detected when users enroll.
Other Email Users: Users within your organization can securely send email
to recipients outside the SMSA.
First, the PGP Universal Server attempts to find a key for the recipient. If
that fails, there are four fallback options, all controlled by mail policy:
bounce the message back to the sender (so it is not sent unencrypted),
send unencrypted, Smart Trailer, and PGP Universal Web Messenger mail.
25
PGP Universal Server The Big Picture
Smart Trailer sends the message unencrypted and adds text giving the
recipient the option of joining the SMSA by installing PGP Universal
Satellite, using an existing key or certificate, or using PGP Universal Web
Messenger. PGP Universal Web Messenger lets the recipient securely read
the message on a secure website; it also gives the recipient options for
handling subsequent messages from the same domain: read the messages
on a secure website using a passphrase they establish, install PGP
Universal Satellite, or add an existing key or certificate to the SMSA.
Installation Overview
The following steps are a broad overview of what it takes to plan, set up, and
maintain your PGP Universal Server environment.
Most of the steps described here are described in detail in later chapters. Steps
1 and 4 are described in the PGP Universal Server Installation Guide. Note that
these steps apply to the installation of a new, stand-alone PGP Universal Server.
If you plan to install a cluster, you must install and configure one PGP Universal
Server following the steps outlined here. Subsequent cluster members will get
most of their configuration settings from the initial server by replication.
The steps to install and configure a PGP Universal Server are as follows:
1 Plan where in your network you want to locate your PGP Universal
Server(s).
Where you put PGP Universal Servers in your network, how many PGP
Universal Servers you have in your network, and other factors all have a
major impact on how you add them to your existing network.
Create a diagram of your network that includes all network components and
shows how email flows; this diagram details how adding a PGP Universal
Server impacts your network.
For more information on planning how to add PGP Universal Servers to your
existing network, see Adding the PGP Universal Server to Your Network in
the PGP Universal Server Installation Guide.
2 Perform necessary DNS changes.
Add IP addresses for your PGP Universal Servers, an alias to your
keyserver, update the MX record if necessary, add keys.<domain>,
hostnames of potential Secondary servers for a cluster, and so on.
Properly configured DNS settings (including root servers and appropriate
reverse lookup records) are required to support PGP Universal Server. Make
sure both host and pointer records are correct. IP addresses must be
resolvable to hostnames, as well as hostnames resolvable to IP addresses.
3 Prepare a hardware token Ignition Key.
26
PGP Universal Server The Big Picture
If you want to add a hardware token Ignition Key during setup, install the
drivers and configure the token before you begin the PGP Universal Server
setup process. See Protecting PGP Universal Server with Ignition Keys (on
377) for information on how to prepare a hardware token Ignition Key.
page
Note: In a cluster, the Ignition Key configured on the first PGP Universal
Server in the cluster will also apply to the subsequent members of the
cluster.
4 Install and configure this PGP Universal Server.
The Setup Assistant runs automatically when you first access the
administrative interface for the PGP Universal Server. The Setup Assistant
is where you can set or confirm a number of basic settings such as your
network settings, administrator password, server placement option, mail
server address and so on. The details of this process are described in
Setting Up the PGP Universal Server in the PGP Universal Server Installation Guide.
Note: If you plan to configure multiple servers as a cluster, you must
configure one server first in the normal manner, then add the additional
servers as cluster members. You can do this through the Setup Assistant
when you install a server that will join an existing cluster, or you can do
this through the PGP Universal Server administrative interface. For more
information see Cluster Member Configuration in the PGP Universal Server Installation Guide.
5 License your server.
You cannot take a PGP Universal Server out of Learn Mode or install
updates until the product is licensed. Once it is licensed, you should check
for product updates and install them if found. For more information, see
Licensing Your Software (on page
51).
If you want the PGP Universal Server to provide mail proxy services, you
must have a PGP Universal Server license with the mailstream feature
enabled. For more information, see Licensing Your Software (on page
51).
6 If you have a PGP key you want to use as your Organization Key with
PGP Universal Server, import it, then back it up.
Your Organization Key does two important things: it is used to sign all user
keys the PGP Universal Server creates and it is used to encrypt PGP
Universal Server backups. This key represents the identity of your
organization, and is the root of the Web-of-Trust for your users.
If your organization uses PGP Desktop and already has an Corporate Key or
Organization Key, and you want to use that key with PGP Universal Server,
you should import it as soon as you have configured your server, then
create a backup of the key.
If your organization does not have an existing key that you want to use as
your Organization Key, use the Organization Key the Setup Assistant
automatically creates with default values. For more information, see
Managing Organization Keys (on page
67).
27
PGP Universal Server The Big Picture
No matter which key you use as your Organization Key, it is very important
to make a backup of the key. Since PGP Universal Server’s built-in back-up
feature always encrypts backups to this key, you need to provide a copy of
your Organization Key to restore your data.
For more information, see Organization Certificate (on page
70).
7 If you have a PGP Additional Decryption Key (ADK) that you want to
use with PGP Universal Server, add it.
An ADK is a way to recover an email message if the recipient is unable or
unwilling to do so; every message that is also encrypted to the ADK can be
opened by the holder(s) of the ADK. You cannot create an ADK with the
PGP Universal Server, but if you have an existing PGP ADK (generated by
PGP Desktop, an ideal scenario for a split key; refer to the PGP Desktop User’s Guide for more information), you can add it to your PGP Universal
Server and use it. For more information, see Additional Decryption Key (ADK) (on page
73).
8 Create a SSL/TLS certificate or obtain a valid SSL/TLS certificate.
You can create a self-signed certificate for use with SSL/TLS traffic.
Because this certificate is self-signed, however, it might not be trusted by
email or Web browser clients. PGP Corporation recommends that you
obtain a valid SSL/TLS certificate for each of your PGP Universal Servers
from a reputable Certificate Authority.
This is especially important for PGP Universal Servers that are accessed
publicly. Older Web browsers might reject self-signed certificates or not
know how to handle them correctly when they encounter them via PGP
Universal Web Messenger or Smart Trailer.
For more information, see Working with Certificates (on page
396).
9 Configure the Directory Synchronization feature if you want to
synchronize an LDAP directory with your PGP Universal Server.
Using the Directory Synchronization feature gives you more control over
who is included in your SMSA, if you have an existing LDAP server.
By default, user enrollment is set to Email enrollment. If you elect to use
LDAP directory enrollment, it assumes that you have an LDAP directory
configured. You can change the client enrollment setting for Directory
Synchronization from the Directory Synchronization Settings page in the
PGP Universal Server administrative interface. You must have an LDAP
directory configured and Directory Synchronization enabled for LDAP user
enrollment to work.
For more information, see Using Directory Synchronization to Manage Users (on page
251).
10 Add trusted keys, configure consumer policy, and establish mail
policy.
28
PGP Universal Server The Big Picture
All these settings are important for secure operation of PGP Universal
Server. For more information on adding trusted keys from outside the
SMSA, see Managing Trusted Keys and Certificates (on page
95). For more
information about consumer policy settings, see Administering Consumer
Policy (on page
Mail Policy (on page
225). For information on setting up mail policy, see Setting
99).
Note: When setting policy for Consumers, PGP Universal Server provides
an option called Out of Mail Stream (OOMS) support. OOMS specifies
how the email gets transmitted from the client to the server when
Protector for Mail Encryption Client cannot find a key for the recipient and
therefore cannot encrypt the message.
OOMS is disabled by default. With OOMS disabled, sensitive messages
that can't be encrypted locally are sent to PGP Universal Server "in the
mail stream" like normal email. Importantly, this email is sent in the clear
(unencrypted). Mail or Network administrators could read these messages
by accessing the mail server's storage or monitoring network traffic.
However, archiving solutions, outbound anti-virus filters, or other systems
which monitor or proxy mail traffic will process these messages normally.
You can elect to enable OOMS, which means that sensitive messages
that can't be encrypted locally are sent to PGP Universal Server "out of the
mail stream." Protector for Mail Encryption Client creates a separate,
encrypted network connection to the PGP Universal Server to transmit the
message. However, archiving solutions, outbound anti-virus filters, or
other systems which monitor or proxy mail traffic will not see these
messages.
During your configuration of your PGP Universal Server you should
determine the appropriate settings for your requirements. This option can
be set separately for each policy group, and is set through the Consumer
Policy settings. For more details on the effects of enabling or disabling
OOMS, see Out of Mail Stream Support.
11 Install and configure additional cluster server members.
You can do this through the Setup Assistant when you install a server that
will join an existing cluster, or you can do this through the PGP Universal
Server administrative interface. Remember that you must configure one
server in the normal manner before you can add and configure additional
servers as cluster members. For more information, see Clustering your PGP Universal Servers (on page
401).
12 Reconfigure the settings of your email clients and servers, if
necessary.
29
PGP Universal Server The Big Picture
Depending on how you are adding the PGP Universal Server to your
network, some setting changes might be necessary. For example, if you
are using a PGP Universal Server placed internally, the email clients must
have SMTP authentication turned on. For PGP Universal Servers placed
externally, you must configure your mail server to relay SMTP traffic to the
PGP Universal Server.
13 Enable SNMP Polling and Traps.
You can configure PGP Universal Server to allow network management
applications to monitor system information for the device on which PGP
Universal Server is installed and to send system and application information
to an external destination. See Configuring SNMP Monitoring (on page
for more information.
14 Distribute PGP Universal Satellite and/or PGP Desktop to your internal
users, if appropriate.
If you want to provide seamless, end-to-end PGP message security without
the need for any user training, have them use PGP Universal Satellite.
Exchange/MAPI and Lotus Notes environments also require the use of PGP
Universal Satellite. PGP Desktop provides more features and user control
than PGP Universal Satellite. For more information, see PGP Universal
Satellite and Configuring PGP Desktop Installations.
361)
15 Analyze the data from Learn Mode.
In Learn Mode, your PGP Universal Server sends messages through mail
policy without actually taking action on the messages, decrypts and verifies
incoming messages when possible, and dynamically creates a SMSA. You
can see what the PGP Universal Server would have done without Learn
Mode by monitoring the system logs.
Learn Mode lets you become familiar with how the PGP Universal Server
operates and it lets you see the effects of the policy settings you have
established before the PGP Universal Server actually goes live on your
network. Naturally, you can fine tune settings while in Learn Mode, so that
the PGP Universal Server is operating just how you want before you go live.
For more information, see Operating in Learn Mode (on page
53).
16 Adjust policies as necessary.
It might take a few tries to get everything working just the way you want.
For example, you might need to revise your mail policy.
17 Perform backups of all PGP Universal Servers before you take them
out of Learn Mode.
This gives you a baseline backup in case you need to return to a clean
installation. For more information, see Backing Up and Restoring System and User Data (on page
383).
18 Take your PGP Universal Servers out of Learn Mode.
30
PGP Universal Server The Big Picture
Once this is done, email messages are encrypted, signed, and
decrypted/verified, according to the relevant policy rules. Make sure you
have licensed each of your PGP Universal Servers; you cannot take a PGP
Universal Server out of Learn Mode until it has been licensed.
19 Monitor the system logs to make sure your PGP Universal Server
environment is operating as expected.

Naming your PGP
4
Universal Server
This section describes how and why to name your PGP Universal Server using
the keys.<domain> convention.
Considering a Name for Your PGP Universal Server
Unless a valid public key is found locally, PGP Universal Servers automatically
look for valid public keys for email recipients by attempting to contact a
keyserver at a a special hostname, keys.<domain>, where <domain> is the
email domain of the recipient.
For example, an internal user at example.com is sending email to
susanjones@widgetcorp.com.” If no valid public key for Susan is found on the
“
Example Corp. PGP Universal Server (keys would be found locally if they are
cached, or if Susan was an external user who explicitly supplied her key via the
PGP Universal Web Messenger service), it automatically looks for a valid public
key for Susan at keys.widgetcorp.com, even if there is no domain policy for
widgetcorp.com on Example’s PGP Universal Server.
Naturally, the Example Corp. PGP Universal Server can only find a valid public
key for “
PGP Universal Server is named using the keys.<domain> convention.
susan@widgetcorp.com” at keys.widgetcorp.com if the Widgetcorp
Caution: PGP Corporation strongly recommends you name your PGP
Universal Server according to this convention, because doing so allows other
PGP Universal Servers to easily find valid public keys for email recipients in
your domain. Make sure to name your externally visible PGP Universal Server
using this convention.
If your organization uses email addresses such as “mingp@example.com” as
well as “
to be reachable at both keys.example.com and keys.corp.example.com.
If you have multiple PGP Universal Servers in a cluster managing an email
domain, only one of those PGP Universal Servers needs to use the
keys.<domain> convention.
Note: Keys that are found using the keys.<domain> convention are treated as
valid and trusted by default.
mingp@corp.example.com,” then you need your PGP Universal Server
37
PGP Universal Server Naming your PGP Universal Server
Alternately, keys.<domain> should be the address of a load-balancing device
which then distributes connections to your PGP Universal Server’s keyserver
service. The ports that would need to be load-balanced are the ones on which
you are running your keyserver service (typically port 389 for LDAP and 636 for
LDAPS).
Another acceptable naming convention would be to name your PGP Universal
Server according to the required naming convention your company uses, and
make sure the server has a DNS alias of keys.<domain>.com.
If you are administering multiple email domains, you should establish the
keys.<domain> convention for each email domain.
If your PGP Universal Server is behind your corporate firewall (as it should be),
you need to make sure that ports 389 (LDAP) and 636 (LDAPS) are open to
support the keys.<domain> convention.
Methods for Naming a PGP Universal Server
There are three ways to name your PGP Universal Server to support the
keys.<domain> convention:
Name your PGP Universal Server “keys.<domain>” on the Host Name
field of the Network Setup page in the Setup Assistant.
Change the Host Name of your PGP Universal Server to keys.<domain>
using the administrative interface on the Network Settings section of the
System > Network page.
Create a DNS alias to your PGP Universal Server that uses the
keys.<domain> convention that is appropriate for your DNS server
configuration.

While you might find that the administrative interface works with other Web
browsers, we recommend these browsers for maximum compatibility.
Logging In
A login name and passphrase for the administrative interface were originally
established when you configured the server using the Setup Assistant. In
addition, the original administrator may have created additional administrators,
and may have configured your PGP Universal Server to accept RSA SecurID
authentication.
To log in to your server’s administrative interface
1 In a Web browser, type https://<domain name of server>:9000/ and
press Enter.
Note: If you see a Security Alert dialog box relating to the security
certificate, it means you need to replace the self-signed certificate created
automatically with a certificate from a public Certificate Authority.
The Login page appears.
39
PGP Universal Server Understanding the Administrative Interface
2 Type the current login name in the Username field.
3 Type the current passphrase or SecurID passcode in the Passphrase field.
(If SecurID authentication is enabled, a message below the Passphrase field
will indicate that a SecurID passcode can be entered. A given administrator
is configured to use either passphrase or SecurID authentication, not both.)
4 Click the Login button or press Enter.
5 If the login credentials are accepted, the System Overview page appears.
6 If the login credentials do not match, an error is displayed. For passphrase
authentication that fails, an "Invalid Login" error appears. For SecurID
authentication, different events may occur. See the following procedure for
more information.
To log in using RSA SecurID authentication
1 Follow steps 1-4 in the procedure above. If your SecurID passcode is
accepted, and no PIN reset is required, the System Overview page appears.
Note: If PGP Universal Server fails to connect with any RSA Manager
server, you will be presented with the standard "Invalid Login" message.
The connection failure will be logged in the PGP Universal Server
Administration log, enabling you to determine whether this was the cause
of the login failure.
2 If the RSA server policy determines that a PIN reset is required, upon
successful login the PIN Reset dialog appears. Depending on the RSA
server policy, you may be able to have the RSA server generate a new PIN
for you, or enter a new PIN manually. When this is done, the System
Overview page appears. For more details see Resetting SecurID PINs (on
375).
page
3 If the RSA server detects a problem with the token code portion of your
passcode, you are asked to re-enter your PIN plus the next code shown on
your SecurID token. Type your PIN and the next token code that appears,
then click Login or press Enter.
4 Based on your RSA server policy, you may be given several chances to
authenticate successfully using the next token code. However, eventually
continued failures will result in a failed login.
Note: Log in events are logged in the PGP Universal Server Administration
log. Successful and failed attempts, and next tokencode requests are logged,
as are problems connecting to the RSA Manager servers.

42).
Managing Alerts
The PGP Universal Server groups failed login attempts into reported login
failures. This feature is intended to make reporting about failed login attempts
more useful, because one or several failed login attempts by a PGP Whole Disk
Encryption user does not necessarily mean an attempted break-in. Use the
Alerts dialog box to choose how many failed login attempts constitutes a login
failure. For example, you can specify that an alert should be triggered after 3
failed login attempts. If 6 failed attempts occur, 2 login failure alerts appear.
Alerts about PGP Whole Disk Encryption login failures appear on the System
Overview page and in the Daily Status Email. Alerts for devices belonging to
specific users appear on the user's Internal Users dialog box.
Alerts are also sent when a user is locked out of a system because he or she
exceeded the number of allowable login failures set on the Disk Encryption tab
of Consumer Policy.
To specify how you want to be notified of PGP Whole Disk Encryption
login failures
1 From the System Overview page, click Manage Alerts.
The Alerts dialog box appears.
2 Specify how many consecutive failed login attempts a single device must
report before the administrator is notified.
3 Choose how long you want login failure alerts to be displayed on the
System Overview page, the Daily Status Email, and the Internal Users
page, in hours or days.
4 Specify how long you want to keep login failure records in the database, in
days.

Overview
Licensing Your Software
This section describes how to license your PGP Universal Server.
Your PGP Universal Server must have a valid license to be taken out of Learn
Mode. In other words, without a valid license, your PGP Universal Server will
never encrypt or sign any email messages.
If you licensed your PGP Universal Server using the Setup Assistant, you do not
have to license it again. If you did not, then you can license it at any time
afterwards using the administrative interface.
The email proxying feature available on the PGP Universal Server can only be
used if you have the Gateway Email license.
The PGP Universal Server can provide security for email messaging by inserting
itself into the flow of email traffic in your network, intercepting, or proxying, that
traffic, and processing it (encrypt, sign, decrypt, verify) based on the applicable
policies.
Manual and Automatic Licensing
When you type your license number, the PGP Universal Server contacts an
authorization server to automatically authorize the license number. If your PGP
Universal Server does not have an active connection to the Internet, you must
contact PGP Support to acquire a manual authorization block.
Caution: The PGP Universal Server must not be behind a proxy server, unless
it is a transparent proxy, to receive licensing information automatically. If the
PGP Universal Server is behind a proxy server, use manual license
authorization.
Licensing a PGP Universal Server
For instructions, see Licensing a PGP Universal Server (on page 366).
51
PGP Universal Server Licensing Your Software
Licensing the Mail Proxy Feature
You must have a PGP Universal Gateway Email license or you cannot use the
Mail Proxies feature on the administrative interface. For information about the
Mail Proxies feature, see Configuring Mail Proxies (on page
171).

Operating in Learn Mode
When you finish configuring a PGP Universal Server using the Setup Assistant, it
begins running in Learn Mode.
In Learn Mode, messages are processed through mail policy, but none of the
actions from the policy are performed. Messages are neither encrypted nor
signed. This functions as a rehearsal, so that you can learn how policies would
affect email traffic if implemented. While running in Learn Mode, the PGP
Universal Server also creates keys for authenticated users so that when Learn
Mode is turned off, the server can secure messages immediately.
After messages go through mail policy, PGP Universal Server decrypts and
verifies incoming messages for which there are local internal or external user
keys. Outgoing messages are sent unencrypted. In Learn Mode, non-RFC
compliant email is sent unprocessed and in the clear. Turn Learn Mode off to
process messages through the mail policy exception chain.
In Learn Mode, the PGP Universal Server:
Creates user accounts with user keys, in accordance with Consumer Policy.
Decrypts messages using internal and external keys stored on the server,
but does not search for keys externally.
Does not encrypt or sign messages.
Will not apply mail policy to messages, and will not take any Key Not Found
action on messages.
Note: Your PGP Universal Server must be licensed before you can take it out
of Learn Mode.
Purpose of Learn Mode
Learn Mode allows you to:
View (by examining the logs) how policies would affect email traffic if
implemented.
Build the SMSA (creating keys for authenticated users, for example) so that
when the server goes live—when Learn Mode is turned off—the server can
secure messages immediately.
Identify mailing lists your users send messages to and add their addresses
to the dictionaries of Excluded Email Addresses. Most likely, users won't
send encrypted messages to a mailing list.
53
PGP Universal Server Operating in Learn Mode
PGP Universal Server decrypts and verifies incoming email while operating
in Learn Mode.
PGP Universal Server still automatically detects mailing lists when Learn
Mode is off, but unless the addresses were retrieved via the Directory
Synchronization feature, they require approval from the PGP Universal
Server administrator to be added to the list of excluded email addresses.
For more information, see Using Dictionaries with Policy (on page
Mailing lists are identified per RFC 2919, List-Id: A Structured Field and
Namespace for the Identification of Mailing Lists, as well as by using
default exclusion rules.
153).
Checking the Logs
The effects of your policies can be checked while Learn Mode is on, even
though the server is not actually encrypting or signing messages.
To check the server’s logs
1 Access the administrative interface for the server.
The administrative interface appears.
2 Click Reporting, then Logs.
The System Logs page appears.
3 Check the logs to see what effect your policies are having on email traffic.
Managing Learn Mode
The PGP Universal Server is put into Learn Mode by the Setup Assistant. If your
server is in Learn Mode, you see a yellow icon, the Change Mode button, in the
upper-right corner of your browser page.
To turn off Learn Mode
1 Click the Change Mode button in the upper-right corner of the page.
The Mail Processing Settings dialog box appears.
2 Deselect Operate in Learn Mode.
3 Click Save.
Learn Mode is turned off.

Managed Domains
8
This section describes how to create and manage the internal domains for
which your PGP Universal Server protects email messages.
About Managed Domains
The Managed Domains page gives you control over the domains for which the
PGP Universal Server is handling email.
Email users from domains being managed by your server are called “internal
users.” Conversely, email users from domains not being managed by your
server but who are part of the SMSA are called “external users.”
For example, if your company is “Example Corporation,” you can have the
domain “example.com” and your employees would have email addresses such
jsmith@example.com.”
as “
If this were the case, you would want to establish “example.com” as a domain
to be managed by your server. When you install your PGP Universal Server you
have the opportunity to add a managed domain in the Setup Assistant. If you do
not set it up at that time, you can use the Managed Domains page to add it. You
can also add additional managed domains from the Managed Domains page, if
you have users with addresses in multiple domains that you want to be
considered internal users.
Managed domains automatically include sub-domains, so in the example above,
users such as “
users. Multi-level domain structures as used by some countries are also
acceptable: for example, the domain “example.co.uk.”
The Managed Domains page accepts Internet DNS domain names and Domino
domains. You must have an Internet DNS domain name, and if you have Notes
users, you must also include the Domino domain name. WINS names (for
example,
Usually, you specify your Internet domain during installation through the Setup
Assistant. If your PGP Universal Server is also managing a Domino server, you
must add your Domino domain name manually through the Managed Domains
page.
For example, if you have an Internet domain "example.com" and a Domino
domain "ExDomino," you would add example.com as the managed domain
during setup, for SMTP addressing. You would then add ExDomino as an
additional managed domain, for Domino addressing.

on creating mail policies.
Managed domains entered on the Managed Domains page populate the
Managed Domains dictionary. The dynamic Managed Domains dictionary
automatically includes subdomains. See Using Dictionaries with Policy (on page
153) for more information on dictionaries.

Adding Managed Domains
To add a domain to the list of managed domains
1 Click Add Managed Domain.
The Add Managed Domain dialog box appears.
2 Type a domain name in the Domain field.
Do not type WINS names (for example,
Internet DNS domain names or Domino domain names.
3 Click Save.
Deleting Managed Domains
If you delete a managed domain, all the user IDs within that domain remain in
the system. Users can still encrypt and sign messages with their keys.
To remove a domain name already on the list of managed domains
1 Click the icon in the Delete column of the domain you want to remove from
the list.

Understanding Keys
9
This chapter introduces some of the concepts related to how Consumer keys
are managed. It introduces the concept of key modes, which are used to control
whether internal and external users can manage their own keys or whether keys
should be managed by PGP Universal Server. It also discusses the use of
Certificate Revocation Lists and key reconstruction blocks.
Choosing a Key Mode For Key Management
When you create PGP Universal Satellite and PGP Desktop installers, you can
choose whether you want internal and external users to be able to manage their
own keys, or whether keys should be managed by the PGP Universal Server.
End-to-end email processing functions refer to encryption, decryption,and
signing performed at the client, rather than on the PGP Universal Server.

Server Key Mode (SKM)—The PGP Universal Server generates and
manages user keys.
Users cannot manage their own keys.
PGP Universal Server administrators have access to private keys.
If a user has a client installation, the user’s keys are downloaded to
the client at each use.
SKM can also be used without client installations; if there is no client
installation, you must use SKM.
The client stores the private key encrypted to a random passphrase,
so users can read email offline.
PGP NetShare does not support SKM.
In PGP Universal Gateway Email environments, existing users with
SKM key mode keys who install PGP Desktop for the first time will be
prompted automatically to re-enroll and create a CKM, GKM, or SCKM
key.
Client Key Mode (CKM)—Users use client software to generate and
manage their own keys.
PGP Universal Server administrators do not have access to private
keys.
CKM user email is secure on the mail server.
CKM users are responsible for backing up their keys; if they lose their
private keys, there is no way to retrieve them.
60
PGP Universal Server Understanding Keys
Users who want to be able to read their email offline and unconnected
to PGP Universal Server must use CKM.
PGP NetShare supports CKM; it requires that users control their own
keys.
PGP Universal Gateway Email does not support CKM.
Guarded Key Mode (GKM)—Users generate and manage their own keys,
and store their passphrase-protected private keys on the server.
GKM is similar to CKM, except that PGP Universal Server stores
protected copies of private keys.
PGP NetShare supports GKM; it requires that users control their own
keys.
PGP Universal Gateway Email does not support GKM.
Server Client Key Mode (SCKM)—Keys are generated on the client.
Private encryption subkeys are stored on both the client and PGP Universal
Server, and private signing subkeys are stored only on the client.
SCKM allows for separate signing and encryption subkeys,
comparable to X.509 signing and encryption keys.
The public and private encryption subkey is on the server, but by
default encryption is not performed on the server.
The public-only signing subkey is on the server. PGP Universal Server
cannot sign email for the user.
Mail processing must take place on the client side to use the SCKM
signing subkey. If you want to use PGP Universal Gateway Email with
SCKM keys, you must be using PGP Universal Server 2.5 or later. PGP
Universal Gateway Email allows email encryption and decryption with
SCKM keys, but email will not be signed.
SCKM is compatible with smart cards, but encryption keys are not
generated on the token. Copy the keys onto the token after
generation.
If an SCKM user resets their key, the entire SCKM key is revoked,
including all subkeys, and remains on the PGP Universal Server as a
non-primary key for the user. This non-primary key can still be used for
decryption, and remain on the PGP Universal Server until manually
removed by the administrator.
SCKM is not supported by legacy PGP Desktop installations before
version 9.0.
PGP NetShare supports SCKM; it requires that users control their own
keys.
61
PGP Universal Server Understanding Keys
Which key management option you choose depends on what your users need
and which client application they use. Server Key Mode is generally appropriate
for PGP Universal Satellite users. Client Key Mode is more appropriate for PGP
Desktop users. If your security policy requires that a user’s signing key is only in
the possession of the user, but the user’s encryption key must be archived,
SCKM is the correct choice.
Recommended Key Mode Compatibility Per PGP Product
If you want to use both PGP Desktop and PGP Universal Gateway Email, your
users need SCKM keys.
If your users only require support for messaging, PGP Universal Satellite and
SKM are sufficient. Both public and private keys are stored on the PGP Universal
Server, and the private key is only temporarily sent to the client application for
message signing and decryption. SKM is not as secure as CKM because the
private keys are not under individual management. Separate signing subkeys are
not available to SKM users.
PGP Desktop has more features than PGP Universal Satellite, and those
features require client-controlled keys. For example, to use the PGP Whole Disk
Encryption option with a hardware token in PGP Desktop, users must be able to
generate and manage the key stored on the Whole Disk token. If you want a
PGP Virtual Disk to be created automatically at installation, that also requires
CKM. PGP NetShare is also unavailable to SKM users.
For more information on key management settings, see Editing Internal User
Policies. For more information on key modes and their relationship to PGP
Universal Satellite, see Key Mode (on page
295).
Adding PGP Desktop Solutions to Existing Gateway Email Environments
PGP NetShare requires users' keys to use CKM, GKM, or SCKM mode. In PGP
Universal Gateway Email environments, existing users with SKM key mode
keys who install PGP Desktop for the first time are prompted automatically to
re-enroll and create a CKM, GKM, or SCKM key.
62
PGP Universal Server Understanding Keys
Enrolling revokes the user's SKM key and replaces it with the key the user
generates using the wizard. Users can continue to decrypt with the revoked
SKM keys, but all new messages are encrypted to the new key and must be
decrypted at the client.
Changing Key Modes
If you allow PGP Desktop users to change their options and allow user-initiated
key generation, users can switch key modes.
If the user’s policy has changed to permit user-managed keys, then the user is
automatically prompted to create a new key, and no further action is necessary.
However, if the user’s policy has always permitted user key management, and
the user wants to switch key modes, the user should follow this procedure.
To change key mode
1 Open PGP Desktop and select the PGP Messaging service whose key
mode you want to determine.
The account properties and security policies for the selected service
appear.
2 Click Key Mode.
The PGP Universal Key Mode page appears, describing your current key
management mode.

How PGP Universal Server Uses Certificate Revocation Lists
A certificate revocation list (CRL) is a list of certificates that have been revoked
before their scheduled expiration date. The PGP Universal Server retrieves CRLs
for certificates from CRL Distribution Points (DP).
The PGP Universal Server checks the CRL DPs automatically before encrypting
a message to a certificate, including certificates for internal and external users,
as well as certificates in the cache. The server also checks the CRL DPs before
importing any internal or external user certificate. It does not check before
importing Trusted Certificates, or before connecting to servers with SSL
certificates.
The PGP Universal Server checks the revocation status of just the recipient's
certificate. It does not check the revocation status of the other certificates in the
signing chain.
Once retrieved, certificate revocation status is stored on the parent certificate,
so the Trusted Certificate for each user certificate stores the list of all the
associated revoked certificates. Once the CRL is stored on the Trusted
Certificate, the PGP Universal Server runs future CRL checks based on the
“next update” date for that list.
Key Reconstruction Blocks
Key reconstruction blocks allow users to retrieve their private keys if they forget
their passphrases.
64
PGP Universal Server Understanding Keys
Key reconstruction blocks contain several user-defined questions and the user's
private key, which is encrypted with the answers to those questions.
PGP Universal Server stores these questions and answers so that users can get
back their private keys in case they lose their passphrases. For example, if a
user writes five questions and answers, they can be asked three (or more) of
the questions to reconstruct their private key.
If an internal PGP Desktop user has uploaded a key reconstruction block to the
PGP Universal Server, you can delete it. You might want to delete a key
reconstruction block if you have already deleted or revoked the associated key
and you do not want the key to be recoverable. If you delete the key
reconstruction block, it is no longer stored on the PGP Universal Server,
although it is possible that the user also has a copy.
Note: Keys created on smart cards and tokens are not compatible with PGP
Desktop's key reconstruction feature.
See Recovering Encrypted Data in an Enterprise Environment (on page 287) for
information on other methods of data recovery.
Managed Key Permissions
Key permissions determine what actions consumers (users or managed
devices) can perform upon managed keys. Key permissions are set in three
ways:
At the group level: permissions can be set that determine how group
members can interact with managed keys. Permissions set for a group are
inherited by all members of the group.
At the consumer level: individual consumers may be granted permissions.
These permissions will exists in addition to the permissions the consumer
inherits from the groups of which it is a member.
At the managed key level: a managed key can have permissions that
specify what actions consumers or groups can take upon it. These are set
individually for a managed key.
Permissions are positive (they allow actions) and are additive: the actions
enabled for a consumer relative to a managed key are combination of the
permissions allowed by the consumer's group membership, plus permissions
allowed for the consumer, plus permissions allowed by the key.
There are no deny permissions.

Managing Organization
10
Keys
This section describes the various keys and certificates you can configure and
use with your PGP Universal Server.
About Organization Keys
There are multiple keys and certificates you can use with your PGP Universal
Server:
Organization Key. Used to sign all user keys the PGP Universal Server
creates and to encrypt server backups.
Organization Certificate. Required to support S/MIME environments.
Additional Decryption Key (ADK). Used to reconstruct messages if the
recipient is unable or unwilling to do so. Every message encrypted to an
external recipient by an internal user is also encrypted to the ADK, allowing
the PGP Universal Server administrator to decrypt any message sent by
internal users, if required to do so by regulations or security policy.
Verified Directory Key. Used to sign keys submitted to the PGP Verified
Directory by external users.
The Organization Keys page provides access to all of these.
Organization Key
Your Organization Key is used to sign all user keys the PGP Universal Server
creates and to encrypt server backups. The Organization Key is what was
referred to as the Corporate Key in the old PGP Keyserver environment.
Warning: You must make a backup of your Organization Key, in case of a
problem with the server. That way, you can restore your server from a backup
using the backup Organization Key.
Each PGP Universal Server is pre-configured with a unique Organization Key
generated by the Setup Assistant. If you would like to use different settings for
this key, you can regenerate the key with the settings you prefer. This should
only be done prior to live deployment of the server or creation of user keys by
the server.
67
PGP Universal Server Managing Organization Keys
The Organization Key automatically renews itself one day before its expiration
date. It renews with all the same settings.
If you have multiple PGP Universal Servers in a cluster, the Organization Key is
synchronized.
An Organization Key’s identification is based on the name of the managed
domain for which the key was created. Organization Keys by convention have
one ID per managed domain so that they can be easily found via a directory
lookup.
The Organization Key information includes the Public Keyserver URL, as
specified on the Services > Keyserver page. Anytime the Public Keyserver URL
changes, that information on the Organization Key changes immediately.
Inspecting the Organization Key
To inspect the properties of an Organization Key
1 Click the name of the Organization Key.
The Organization Key Info dialog box appears.
2 Inspect the properties of the Organization Key.
3 To export either just the public key portion of the Organization Key or the
entire keypair, click the Export button and save the file to the desired
location. Optional: You can protect your Organization Key with a passphrase
when you export it.
When you export the Organization Key you also get the Organization
Certificate. You can use PGP Desktop to extract the Organization Certificate
from the Organization Key.
4 Click OK.
If you are going to regenerate your Organization Key, you should use a fairly
high bit size, such as 2048. However, if you are going to be using X.509
certificates and S/MIME, be aware that many clients only support up to
1024 bits; thus you may want to use 1024 bits for maximum compatibility
with S/MIME. All clients can be expected to support at least 4096 bits.
Regenerating the Organization Key
Warning: Changing the Organization Key makes all previous backups
undecryptable and all validity signatures on the keys of internal users are
unverifiable until they are automatically renewed. Only change the
Organization Key if you fully understand the consequences of this action.
68
PGP Universal Server Managing Organization Keys
Caution: Changing the Organization Key deletes Ignition Keys. If you have
hard or soft token Ignition Keys configured, regenerating the Organization Key
deletes them. Without an Ignition Key, PGP Universal Web Messenger
messages are not stored encrypted.
Note: The Organization Key signs all Trusted Keys and Certificates. If you
regenerate the Organization Key, the signature on the Trusted Keys and
Certificates becomes invalid. You must re-import all Trusted Keys and
Certificates to have them signed by the new Organization Certificate. For
more information, see Managing Trusted Keys and Certificates (on page 95).
To regenerate an Organization Key
1 Click Regenerate in the Action column of the Organization Key whose
properties you want to change.
2 The following warning dialog box appears:
Regenerating the Organization Key will cause problems with existing key
signatures and backups. Any existing Ignition Keys and Organization
Certificate will also be removed. Are you sure you want to proceed?
3 Click OK.
The Organization Key Generation dialog box appears.
4 Make the desired changes to the properties of the Organization Key.
5 Click Generate.
Importing an Organization Key
You also have the option of importing an existing PKCS #12 key and using that
as your Organization Key.
Caution: Importing an Organization Key deletes Ignition Keys. If you have
hard or soft token Ignition Keys configured, importing an Organization Key
deletes them. Deleting the Ignition Key stops PGP Universal Web Messenger
from being stored encrypted
To import an Organization Key
Click the icon in the Import column of the Organization Key row.
1 The following warning dialog box appears:
Importing a new Organization Key will cause the current key (and
Organization Certificate, if any) to be deleted, and will cause problems with
existing key signatures and backups. Any existing Ignition Keys will also be
removed. Are you sure you want to proceed?
2 Click OK.
69
PGP Universal Server Managing Organization Keys
The Import Organization Key dialog box appears.
3 Do one of the following:
If you want to import a key that has been saved as a file, click Browse
to locate the file of the key you want to import.
If you want to import a key by cutting and pasting, copy the key you
want to be your Organization Key to the Clipboard and paste it into the
Key Block box.
4 Type the passphrase for the key, if required.
5 Click Import.
The Organization Key you imported appears in the Organization Key row.
Organization Certificate
An Organization Certificate is required for S/MIME support. You can only have
one Organization Certificate attached to your Organization Key. You cannot
restore from a backup with more than one Organization Certificate associated
with your Organization Key.
The PGP Universal Server will automatically generate certificates as well as keys
for new internal consumers created after you import or generate an Organization
Certificate. All internal consumers receive a certificate added to their keys within
a certain amount of time, between 24 hours to two weeks. However,
certificates issued by the old Organization Certificate remains on users’ keys
until the certificate expires. PGP Universal Server also creates separate signing
and encryption certificates for imported SKM and SCKM internal keys, based on
the appropriate subkey. PGP Universal Server creates single signing and
encryption certificates for imported CKM and GKM keys, based on the user's
topkey.
You have several options for dealing with Organization Certificates. You can:
Create a self-signed Organization Certificate. Unfortunately, a self-signed
Organization Certificate will not be universally recognized, so PGP
Corporation recommends using a certificate from a recognized Certificate
Authority (CA). Self-signed X.509 Organization Certificates are version 3.
Create a Certificate Signing Request for a certificate authorized by an
existing CA. When you receive the certificate back from the CA as a file,
you will need to import that file.
Import an existing certificate to use as your Organization Certificate.
Imported X.509 certificates must be version 3.
To enable S/MIME support, the certificate of the issuing Root CA, and all other
certificates in the chain between the Root CA and the Organization Certificate,
are on the list of trusted keys and certificates on the Trusted Keys and
Certificates page.
70
PGP Universal Server Managing Organization Keys
A self-signed Organization Certificate has the same expiration date as the
Organization Key, unless the Organization Key is set never to expire. If the
Organization Key never expires, the Organization Certificate expires 10 years
from the date you generate it. You must regenerate the Organization Certificate
before it expires and distribute the new Certificate to anyone who uses your old
Organization Certificate as a trusted root CA.

Additional Decryption Key (ADK)
An Additional Decryption Key (ADK) is a way to retrieve an email message or
other encrypted data if the recipient is unable or unwilling to do so and if
required by regulation or security policy. Every message sent by an internal user
is also encrypted to the ADK. Messages encrypted to the ADK can be opened
by the recipient and/or by the holder(s) of the ADK. The ADK is also added to
disks encrypted with PGP Whole Disk Encryption.
If you have an Additional Decryption Key uploaded, all outbound email is
encrypted to it when mail policy is applied. This setting appears in the Send (encrypted/signed) action and the setting cannot be disabled. For more
information, see the chapter "Setting Mail Policy."
You can create an ADK with PGP Desktop, then add it to your PGP Universal
Server and use it.
You can also add an ADK to a consumer policy. Clients with a policy with an
ADK have all messages and other data encrypted to the policy-specific ADK as
well as to the Organization ADK.
Note: S/MIME messages are not encrypted to the ADK.
If you use an ADK, PGP Universal Server adds the ADK to all new keys that it
generates and all outbound email messages are automatically encrypted to it.
If you are going to use an ADK on your PGP Universal Server, you should import
it prior to generating any user keys. You should also try to avoid changing to a
different ADK later on, because doing so results in some keys being associated
with the old ADK and some with the new ADK. If you add or change an ADK, it
is only associated with the keys of new users. Existing users do not get that
ADK added to their key.
Only PGP keys can be used as ADKs.

Keys
PGP Key Management Server (KMS) is new technology that centralizes the
management of multiple kinds of encryption keys for your organization onto a
single server, thus allowing multiple applications in your enterprise to operate
against the same set of keys.
To accommodate this new PGP KMS technology, new terms and concepts are
being used to describe how PGP applications understand keys, users, and
servers, and the relationships between them.
With PGP KMS, a Consumer is an identity associated with a person or a device.
A consumer can be a User, generally identified with a person. A user has a key,
can encrypt things, send and receive email, and so on. One person can have
more than one user identity (for example, they could be the holder of a
corporate ADK as one identity and a PGP Desktop user as a second identity,
each identity having a different PGP keypair).A consumer can also be a
Managed Device, such as a web server that handles credit cards or a bank's
automated teller machine. Each consumer has a Managed Key, which is a
keypair managed by PGP KMS for the consumer.
A Managed Key is a PGP keypair with some additional information. A managed
key can be used to encrypt, decrypt, sign, and verify. It is also known as a
Managed Asymmetric Key, or MAK, in the USP API and in PGP Command Line.
A managed key may or may not have associated symmetric keys, symmetric
key series, or custom data objects.
Symmetric Keys (also known as Managed Encryption Keys, or MEKs) are
always associated with a managed key. A symmetric key can be used to encrypt
and decrypt; it cannot sign or verify. Any number of symmetric keys can be
associated with a managed key. Symmetric keys can have a Validity Period,
allowing them to be valid for a specified period. At the end of the specified
period, the symmetric key expires and a new symmetric key can be
automatically created. The old symmetric key is retained in an expired state and
kept, to decrypt older data if necessary.
A Symmetric Key Series (or MEK series) is series of symmetric keys, each one
of which is automatically created, is valid for the duration of its Validity Period,
and then expires and is replaced by a new symmetric key. Consumers using a
symmetric key series can be automatically notified of a new symmetric key so
that they can synchronize to the series and thus use the correct symmetric key
at the correct time. In other cases, no notification is needed; when you encrypt
against the symmetric key series, the active symmetric key is used
automatically.
77
PGP Universal Server Administering Managed Keys
Custom Data Objects are encrypted data objects stored on a PGP KMS and
associated with a managed key. It is just like a regular encrypted file except it is
stored on a PGP KMS. Custom data objects are also known as Managed Secure
Data, or MSDs).
Symmetric Keys and Custom Data Objects can be created, edited, searched for
and deleted by external applications using the USP APIs, or through PGP
Command Line commands. They can be viewed through the PGP Universal
Server administrative interface, but cannot be created or modified by a PGP
Universal Server administrator.
Viewing Managed Keys
Managed keys can be associated with several types of consumers: internal,
external, and verified directory users, and managed devices for which keys have
been imported.
There are a number of paths available to view managed keys.
For a User, you can access the Managed Key Information page by clicking
the Key ID from the Managed Key section of the user's User Information
page.
For a Managed Device, you can access the Managed Key Information page
by clicking the Key ID from the Managed Key section of the Managed
Device Information page.
The organization key and Verified Directory signing keys are also managed keys,
but are discussed in Managing Organization Keys (on page

Permissions
Managed Key permissions are similar to the permissions that can be granted to
a Consumer or Group, with an important exception: while group and consumer
permissions define the actions a consumer or group member can perform, a
Managed Key permission defines what actions others (Groups or Consumers)
can perform upon the Managed Key.
For example, a Consumer may be given a permission such as:
Can read public key of Managed Key Joe Smith
jsmith@example.com>
<
while a Managed Key may have a permission such as:
Group Marketing can delete
meaning that any Consumer that is a member of the group Marketing can delete
this key.

Symmetric Key Series
A KMS license is required to access Symmetric Key Series and Symmetric Keys.
Symmetric keys (also known as Managed Encryption Keys, or MEKs) can be
used, through the USP API or the PGP Command Line commands, to encrypt
and decrypt data. A symmetric key typically has a limited life span, with a
specific validity period that determines how long the key remains valid. At the
end of the validity period, the current key expires and is replaced by a new
symmetric key.
The Symmetric Key Series is the set of the current plus expired keys,
maintained by PGP Universal Server. The currently valid key is used to encrypt
content during its validity period, and to decrypt content encrypted during this
validity period. The expired keys are maintained in order to decrypt content that
was encrypted in the past; PGP Universal Server determines which key to use
for decryption based on the date the content was encrypted.

Custom Data Objects are always associated with (owned by) a Managed Key.
They can be used to store arbitrary data objects securely in the PGP Universal
Server database. They are created and manipulated using the USP API or PGP
Command Line commands.
Custom Data Objects can be viewed through the PGP Universal Server
administrative interface. The administrator can also add and edit attributes and
permissions for a Custom Data Object.
To view a list of the Custom Data Objects associated with a managed key
1 From the Managed Key Information page, click the Custom Data
Objects... button to display the list of Custom Data Objects owned by this
managed key.
For each object in the list, this page shows its name, its size (in kbytes), and
its MIME type.
PGP Universal Server supports the MIME types for image files, plain text,
rich text, and PDF.

Approving Pending Keys
Internal Users
In addition to automatically creating a key for your email users or manually
adding internal users, you can allow internal users to submit their own keys
through the PGP Verified Directory. Allowing user key submission is useful for
internal users who already have keys, such as existing PGP Desktop users who
of course would have their own PGP key. If the user already has a PGP key, and
the new key is approved, the new key replaces the old key.
91
PGP Universal Server Administering Managed Keys
PGP Desktop users upload their public keys through the PGP Verified Directory
interface at the interface and port you configure on the Verified Directory page.
They can also upload keys through the PGP Desktop "Send To" function.
On the Verified Directory page, you can specify how you want these usersubmitted keys approved. If you have set the PGP Verified Directory to require
either a confirmation email from the user or to require you, the administrator, to
manually approve the key, the user’s PGP key status is marked pending. See
Configuring the PGP Verified Directory (on page
Verified Directory.
To manually approve the key submission
1 From the Internal Users page, click the plus sign icon to approve the key.
2 Click the minus sign icon to deny the submitted key.
3 Click the delete icon to delete the user.

to approve the key.
2 Click the minus sign icon to deny the submitted key.
3 Click the delete icon to delete the user.
Or
1 To approve multiple user keys, click the check box at the far right end of the
row of each of the directory user key you want to approve.
2 Select Approve Selected or Approve All from the Options menu.
Revoking Managed Keys
Revoking a key removes the Organization Key signature from the key. Only keys
for which the PGP Universal Server has the private key can be revoked; that is,
only the keys of SKM users can be revoked. The Revoke button is disabled for
all other keys.
If you revoke an internal user's managed key, it continues being published via
the LDAP server, but appears marked as a revoked key, and it appears on the
Certificate Revocation Lists.
92
PGP Universal Server Administering Managed Keys
Once you revoke a key, you cannot un-revoke it.
Note: Revoking a key is safer than deleting a user because the private key
material is preserved, which means that decryption continues to work.
To revoke the managed key of an internal user
1 Select the user you want from the Internal Users page.
The Internal User Information dialog box appears.
2 From the Managed Keys tab, click the Revoke icon next to the key you
want to Revoke.

Managing Trusted Keys

Overview
Trusted Keys
and Certificates
This section describes how trusted keys and certificates are used with your PGP
Universal Server. You can find the list of trusted keys at Organization >
Trusted Keys.
The Trusted Keys and Certificates page lists keys and certificates that are not
part of the SMSA created by PGP Universal Server but which nevertheless you
do trust.
In those cases where your PGP Universal Server cannot find a public key for a
particular user on any of the keyservers you have defined as trusted, it also
searches the default directories. If it finds a key in one of the default directories,
it trusts (and therefore can use) that key only if it has been signed by one of the
keys in the trusted keys list.
For example, if your company’s law firm uses a PGP Corporate Signing Key
(CSK), you can add this key as a trusted key. Then, if someone in your firm
wants to send a message to someone at the law firm and the PGP Universal
Server finds that person’s key, signed by the law firm’s CSK, in a default
directory, then that key can be used by the server to securely send the message
to the recipient at the law firm.
Trusted Certificates
PGP Universal Server can use S/MIME only if it has the root certificates from
the CAs available to verify the client certificates. These CAs can be in your
company or they can be an outside-managed CA, such as VeriSign.
To enable S/MIME support, the certificate of the issuing Root CA, and all other
certificates in the chain between the Root CA and the Organization Certificate,
are on the list of trusted keys and certificates on the Trusted Keys and
Certificates page.
95
PGP Universal Server Managing Trusted Keys and Certificates
PGP Universal Server comes with information on many public CAs already
installed on the Trusted Keys and Certificates page. Only in-house CAs or new
public CAs that issue user certificates need to be manually imported. You can
inspect, export (save on your computer), or delete the root certificates at any
time.
Trusted Certificates can be in any of the following formats: .cer, .crt, .pem and
.p7b.
Adding a Trusted Key or Certificate
To add a trusted key or certificate
1 On the Trusted Keys and Certificates page, click Add Trusted Key.
The Add Trusted Key dialog box appears.
2 Do one of the following:
To import a trusted key saved in a file, click Browse and choose the
file on your system that contains the trusted key or certificate you
want to add.
To import a key in key block format, paste the key block of the trusted
key or certificate into the Import Key Block box (you need to copy the
text of the trusted key or certificate first to paste it).
3 If desired, select any of the following:
Trust key for verifying mail encryption keys. Enable this option to
trust the key or certificate added to verify signatures on keys from
default keyservers.
Trust key for verifying SSL/TLS certificates (only valid if
importing X.509 certificate). Enable this option to trust the X.509
certificate added to verify SSL/TLS certificates presented from remote
SMTP/POP/IMAP mail servers.
Trust key for verifying keyserver client certificates (only valid if
importing X.509 certificate). Enable this option to trust the X.509
certificate added to verify keyserver client authentication certificates.
4 Click Save.
Note: SSL v1.0 certificates are not supported.
