About PGP Desktop 10.1

for Mac OS X

PGP Desktop is a security tool that uses cryptography to protect your data against unauthorized access.

PGP Desktop protects your data while being sent by email or by instant messaging (IM). It lets you encrypt your entire hard drive or hard drive partition (on Windows systems)—so everything is protected all the time—or just a portion of your hard drive, via a virtual disk on which you can securely store your most sensitive data. You can use it to share your files and folders securely with others over a network. It lets you put any combination of files and folders into an encrypted, compressed package for easy distribution or backup. Finally, use PGP Desktop to shred (securely delete) sensitive files—so that no one can retrieve them—and shred free space on your hard drive, so there are no unsecured remains of any files.

Use PGP Desktop to create PGP keypairs and manage both your personal keypairs and the public keys of others.

To make the most of PGP Desktop, you should be familiar with PGP Desktop Terminology (on page public-key cryptography, as described in Conventional and Public Key Cryptography (on page

9). You should also understand conventional and

12).

What's New in PGP Desktop for Mac OS X Version 10.1

Building on PGP Corporation’s proven technology, PGP Desktop 10.1 for Mac OS X includes numerous improvements and the following new and resolved features.

PGP® Desktop for Mac OS X About PGP Desktop 10.1 for Mac OS X

Messaging

 Improvements have been made to annotations. In a PGP Universal

Server-managed environment, your administrator can now specify where the email annotation will be, such as end of message rather than wrapped around the message.

 You can now protect sent message copies for IMAP accounts (available for

standalone installations only) to provide additional security so you can protect sensitive emails that you have sent using your IMAP account. Choose to Encrypt, Encrypt and Sign, or Sign Only messages as they are copied to your IMAP Sent Items mailbox.

 In a managed environment, your PGP Universal Server administrator can

set policy to enable you to decide if you want to perform signature verification on email messages. If enabled, a new button and/or menu option appears in your Microsoft Outlook or Lotus Notes email client. The button or option will be in the default state set by your administrator but you can choose to override this setting.

 In a managed environment, your PGP Universal Server administrator may

have specified certain PGP Notifier settings (for example, whether notifications are to be displayed or the location of the notifier).

 X.509 certificates included in an S/MIME email message sent to you can

now be imported to your key ring. The same settings you have specified when public keys are found apply to these certificates. If specified, PGP Desktop extracts and then imports the X.509 certificate to your keyring. If you want to encrypt email using imported certificates, be sure to manually sign the certificate.

 In a managed environment, your PGP Universal Server administrator may

have specified a setting so that additional information is included in the Non-Delivery Receipt when a message is blocked. If PGP Desktop is unable to find a key for one or more of the recipients in a group list, the email addresses are listed in the Error Details of the Non-Delivery Receipt.

PGP Portable

 A link for More Info is now available on the PGP Portable dialog box

displayed when you access data on the device. Your browser launches and the PGP Corporation Support site page is displayed.

 You can now view available disk space and total size of the PGP Portable

Disk once the disk has been mounted. When you move your cursor over the dock item for a few seconds, the PGP Notifier message appears and displays the mount status of the PGP Portable Disk as well as the updated disk space information.

PGP® Desktop for Mac OS X About PGP Desktop 10.1 for Mac OS X

PGP Whole Disk Encryption

 AES-128 and AES-256 cipher algorithm for PGP Desktop for Mac OS X

have been enhanced to improve performance of encryption and decryption times as well as disk access times for encrypted disks.

 Enhancement to force the encryption of boot drives, by policy. This

includes forcing encryption if policy changed (for example, you previously did not have to encrypt boot drives, and your administrator modified policy to require encryption).

Using this Guide

This Guide provides information on configuring and using the components within PGP Desktop. Each chapter of the guide is devoted to one of the components of PGP Desktop.

“Managed” versus “Unmanaged” Users

A PGP Universal Server can be used to control the policies and settings used by components of PGP Desktop. This is often the case in enterprises using PGP software. PGP Desktop users in this configuration are known as managed users, because the settings and policies available in their PGP Desktop software are pre-configured by a PGP administrator and managed using a PGP Universal Server. If you are part of a managed environment, your company may have specific usage requirements. For example, managed users may or may not be allowed to send plaintext email, or may be required to encrypt their disk with PGP Whole Disk Encryption.

Users not under the control of a PGP Universal Server are called unmanaged or standalone users.

This document describes how PGP Desktop works in both situations; however, managed users may discover while working with the product that some of the settings described in this document are not available in their environments. For more information, see Using PGP Desktop with PGP Universal Server (on page

207).

Features Customized by Your PGP Universal Server Administrator

If you are using PGP Desktop as a "managed" user in a PGP Universal Server-managed environment, there are some settings that can be specified by your administrator. These settings may change the way features are displayed in PGP Desktop.

PGP® Desktop for Mac OS X About PGP Desktop 10.1 for Mac OS X

 Disabled features. Your PGP Universal Server administrator can enable or

disable specific functionality. For example, your administrator may disable the ability to create PGP Zip archives, or to create PGP NetShare protected folders (on Windows systems).

When a feature is disabled, the control item in the left side is not displayed and the menu for that feature is not available. The graphics included in this guide depict the default installation with all features enabled. The PGP Desktop interface may look different if your administrator has customized the features available.

Conventions Used in This Guide

Notes, Cautions, and Warnings are used in the following ways.

Notes: Notes are extra, but important, information. A Note calls your

attention to important aspects of the product. You will be able to use the product better if you read the Notes.

Cautions: Cautions indicate the possibility of loss of data or a minor security

breach. A Caution tells you about a situation where problems could occur unless precautions are taken. Pay attention to Cautions.

Warnings: Warnings indicate the possibility of significant data loss or a major

security breach. A Warning means serious problems are going to happen unless you take the appropriate action. Please take Warnings very seriously.

Who Should Read This Document

This document is for anyone who is going to be using the PGP Desktop for Mac OS X software to protect their data.

Note: If you are new to cryptography and would like an overview of the

terminology and concepts in PGP Desktop, see An Introduction to Cryptography (it was installed onto your computer when you installed PGP

Desktop).

About PGP Desktop Licensing

A license is used within the PGP software to enable the functionality you purchased, and sets the expiration of the software. Depending on the license you have, some or all of the PGP Desktop family of applications will be active. Once you have entered the license, you must then authorize the software with PGP Corporation, either manually or online.

PGP® Desktop for Mac OS X About PGP Desktop 10.1 for Mac OS X

PGP Desktop Terminology

To make the most of PGP Desktop, you should be familiar with the terms in the following sections.

PGP Product Components

PGP Desktop and its components are described in the following list. Depending on your license, you may not have all functionality available. For more information, see About PGP Desktop Licensing (on page

 PGP Desktop: A software tool that uses cryptography to protect your data

against unauthorized access. PGP Desktop is available for Mac OS X and Windows.

 PGP Messaging: A feature of PGP Desktop that automatically and

transparently supports all of your email clients through policies you control. PGP Desktop accomplishes this using a new proxy technology; the older plug-in technology is also available. PGP Messaging also protects many IM clients, such as AIM and iChat (both users must have PGP Messaging enabled).

 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. You can use PGP Whole Disk Encryption and PGP Virtual Disk volumes on the same system. On Windows systems, you can protect whole disk encrypted drives with a passphrase or with a keypair on a USB token for added security.

5).

PGP® Desktop for Mac OS X PGP Desktop Basics

 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 Keys: A feature of PGP Desktop that gives you complete control

over both your own PGP keys, and the keys of those persons with whom you are securely exchanging email messages.

 PGP Virtual Disk volumes: 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 even create additional users for a volume, so that people you authorize can also access the volume. The PGP Virtual Disk feature is especially useful on laptops, because if your computer is lost or stolen, the sensitive data stored on the PGP Virtual Disk is protected against unauthorized access.

 PGP Shred: A feature of PGP Desktop that lets you securely delete

data from your system. PGP Shred overwrites files so that even file recovery software cannot recover them.

 PGP Viewer: Use PGP Viewer decrypt, verify, and display

messages outside the mail stream

 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: A tool for enterprises to automatically and transparently

secure email messaging for their employees. If you are using PGP Desktop in a PGP Universal Server-managed environment, your messaging policies and other settings may be controlled by your organization’s PGP administrator.

 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 Desktop is designed to work closely with the PGP Global Directory.

Terms Used in PGP Desktop

Before you use PGP Desktop, you should be familiar with the following terms:

PGP® Desktop for Mac OS X PGP Desktop Basics

 Decrypting: The process of taking encrypted (scrambled) data and making

it meaningful again. When you receive data that has been encrypted by someone using your public key, you use your private key to decrypt the data.

 Encrypting: The process of scrambling data so that if an unauthorized

person gets access to it, they cannot do anything with it. The data is so scrambled, it’s meaningless.

 Signing: The process of applying a digital signature to data using your

private key. Because data signed by your private key can be verified only by your public key, the ability to verify signed data with your public key proves that your private key signed the data and thus proves the data is from you.

 Verifying: The process of proving that the private key was used to digitally

sign data by using that person’s public key. Because data signed by a private key can only be verified by the corresponding public key, the fact that a particular public key can verify signed data proves the signer was the holder of the private key.

 Keypair: A private key/public key combination. When you create a PGP

“key”, you are actually creating a keypair. As your keypair includes your name and your email address, in addition to your private and public keys, it might be more helpful to think of your keypair as your digital ID—it identifies you in the digital world as your driver’s license or passport identifies you in the physical world.

 Private key: The key you keep very, very private. Only your private key can

decrypt data that was encrypted using your public key. Also, only your private key can create a digital signature that your public key can verify.

Caution: Do not give your private key, or its passphrase, to anyone! And

keep your private key safe.

 Public key: The key you distribute to others so that they can send

protected messages to you (messages that can only be decrypted by your private key) and so they can verify your digital signature. Public keys are meant to be widely distributed.

Your public and private keys are mathematically related, but there’s no way to figure out your private key if someone has your public key.

 Keyserver: A repository for keys. Some companies host keyservers for the

public keys of their employees, so other employees can find their public keys and send them protected messages. The PGP Global Directory

https://keyserver.pgp.com) is a free, public keyserver hosted by PGP

( Corporation.

PGP® Desktop for Mac OS X PGP Desktop Basics

 Smart cards and tokens: Smart cards and tokens are portable devices on

which you can create your PGP keypair or copy your PGP keypair. Creating your PGP keypair on a smart card or token adds security by requiring possession of the smart card or token in order to encrypt, sign, decrypt, or verify. So even if an unauthorized person gains access to your computer, your encrypted data is secure because your PGP keypair is with you on your smart card or token. Copying your PGP keypair to a smart card or token is a good way to use it away from your main system, back it up, and distribute your public key. Smart cards and tokens are not available for key storage when used with PGP Desktop for Mac OS X.

Conventional and Public Key Cryptography

Conventional cryptography uses the same passphrase to encrypt and decrypt

data. Conventional cryptography is great for data that isn’t going anywhere (because it encrypts and decrypts quickly). However, conventional cryptography is not as well suited for situations where you need to send encrypted data to someone else, especially if you want to send encrypted data to someone you have never met.

Public-key cryptography uses two keys (called a keypair) for encrypting and decrypting. One of these two keys is your private key; and, like the name suggests, you need to keep it private. Very, very private. The other key is your public key, and, like its name suggests, you can share it with the general public. In fact, you’re supposed to share.

Public-key cryptography works this way: let’s say you and your cousin in another city want to exchange private messages. Both of you have PGP Desktop. First, you both need to create your keypair: one private key and one public key. Your private key you keep secret, your public key you send to a public keyserver like the PGP Global Directory (keyserver.pgp.com), which is a public facility for distributing public keys. (Some companies have their own private keyservers.)

Once the public keys are on the keyserver, you can go back to the keyserver and get your cousin’s public key, and she can go to the keyserver and get yours (there are other ways to exchange public keys; for more information, see Working with PGP Keys (on page encrypted email message that only your cousin can decrypt, you encrypt it using your cousin’s public key. What makes this work is that only your cousin’s private key can decrypt a message that was encrypted using her public key. Even you, who have her public key, cannot decrypt the message once it has been encrypted using her public key. Only the private key can decrypt data

that was encrypted with the corresponding public key.

Your public and private keys are mathematically related, but there’s no feasible way to figure out someone’s private key if you just have a public key.

Using PGP Desktop for the First Time

PGP Corporation recommends the following procedure for getting started with PGP Desktop:

1 Install PGP Desktop on your computer.

If you are a corporate user, your PGP administrator may have specific installation instructions for you to follow or may have configured your PGP installer with certain settings. Either way, this is the first step.

2 Let the Setup Assistant be your guide.

To help you get started, after you install PGP Desktop and reboot your computer, the Setup Assistant is displayed. It assists with:

 Licensing PGP Desktop

 Creating a keypair—with or without subkeys (if you do not already

have a keypair).

 Publishing your public key on the PGP Global Directory.

 Enabling PGP Messaging

 Giving you a quick overview of other features.

If your PGP Desktop installer application was configured by a PGP administrator, the Setup Assistant may perform other tasks.

3 Exchange public keys with others.

After you have created a keypair, you can begin sending and receiving secure messages with other PGP Desktop users (once you have exchanged public keys with them). You can also use the PGP Desktop disk-protection features.

Exchanging public keys with others is an important first step. To send them secure messages, you need a copy of their public key, and to reply with a secure message, they need a copy of your public key. If you did not upload your public key to the PGP Global Directory using the Setup Assistant, do so now. If you do not have the public key for someone to whom you want to send messages, the PGP Global Directory is the first place to look. PGP Desktop does this for you—when you send email, it finds and verifies the keys of other PGP Desktop users automatically. It then encrypts your message to the recipient public key, and sends the message.

4 Validate the public keys you get from untrusted keyservers.

PGP® Desktop for Mac OS X PGP Desktop Basics

When you get a public key from an untrusted keyserver, try to make sure that it has not been tampered with, and that the key really belongs to the person it names. To do this, use PGP Desktop to compare the unique fingerprint on your copy of someone’s public key to the fingerprint on that person’s key (a good way to do that is by telephoning the key’s owner and having them read you the fingerprint information so that you can compare it). Keys from trusted keyservers like the PGP Global Directory have already been verified.

5 Start securing your email, files, and instant message (IM) sessions.

After you have generated your keypair and exchanged public keys, you can begin encrypting, decrypting, signing, and verifying email messages and files. The secure IM chat session feature generates its own keys automatically, so you can use this feature even before you generate your keypair. The only requirement is that you must be chatting with another PGP Desktop user for the chat session to be secured.

6 Watch for information boxes from the PGP Desktop Notifier feature to

appear.

As you send or receive messages, or perform other PGP Desktop functions, the PGP Desktop Notifier feature displays information boxes that appear in whichever corner of the screen you specify. These PGP Notifier boxes tell you the action that PGP Desktop took, or will take. After you grow familiar with the process of sending and receiving messages, you can change options for the PGP Notifier feature—or turn it off.

7 After you have sent or received some messages, check the logs to

make sure everything is working correctly.

If you want more information than the Notifier feature displays, the PGP Log provides detailed information about all messaging operations.

8 Modify your messaging policies, if necessary.

Email messages are sent and received—automatically and seamlessly—if PGP Desktop messaging policies are configured correctly. If your message recipient has a key on the PGP Global Directory the default PGP Desktop policies provide opportunistic encryption. Opportunistic encryption means that, if PGP Desktop has what it needs (such as the recipient's verified public key) to encrypt the message automatically, then it does so. Otherwise, it sends the message in clear text (unencrypted). The default PGP Desktop policies also provide optional forced encryption. This means that, if you include the text “[PGP]” in the Subject line of a message, then the message must be sent securely. If verified keys cannot be found, then the message is not sent, and a Notifier box alerts you.

9 Start using the other features in PGP Desktop.

Along with its messaging features, you can also use PGP Desktop to secure the disks that you work with:

PGP® Desktop for Mac OS X PGP Desktop Basics

 Use PGP Whole Disk Encryption to encrypt a boot disk, disk partition

(on Windows systems), external disk, or USB thumb drive. All files on the disk or partition are secured — encrypted and decrypted on the fly as you use them. The process is completely transparent to you.

 Use PGP Virtual Disk to create a secure “virtual hard disk.” You can

use this virtual disk like a bank vault for your files. Use PGP Desktop or Windows Explorer or the Mac OS X finder to unmount and lock the virtual disk, and your files are secure, even if the rest of your computer is unlocked.

 Use PGP Zip to create compressed and encrypted PGP Zip archives.

These archives offer an efficient way to transport or store files securely.

 Use PGP Shredder to delete sensitive files that you no longer need.

PGP Shredder removes them completely, eliminating any possibility of recovery.
