 encrypt: the process of "scrambling" data so that it is not usable unless you

perly authenticate.

pro

 decrypt: the process of "unscrambling" encrypted data.  master boot record (MBR): software on a disk that is "in front" of the

parti

tion table; that is, it is implemented during the startup process before

the operating system itself. The instructi

MBR is replaced with the PGPMBR.

 PGPMBR: an MBR from PGP Corporation that implements the PGP

BootGuard. Once a disk is i

nstrumented, even if it is not fully encrypted,

subsequent startups will bring up PGP BootGuard.

 PGP BootGuard: the screen that appears after instrumenting a disk that

requires authentication is operating system will not lo

not provided, the boot process will not continue; the

ad and the system will not be usable.

 uninstrument: removing the PGPMBR and replacing it with the original

Linux MBR (which was saved when the

disk was instrumented).

 whole disk recovery token (WDRT): an additional passphrase for a whole

disk encrypte

d disk that is passed to the appropriate PGP Universal Server

if the disk is part of a PGP Universal-managed environment.

 PGP Universal Server: a management console for securing data from PGP

Corporation.

PGP WDE for Linux User's Guide Introduction

 managed user: someone using PGP Whole Disk Encryption for Linux in a

PGP Universal Server-managed environment. Managed users receive policies and settings from their PGP Universal Server.

 enroll: the process of a user in a PGP Universal Server-managed

nment contacting their PGP Universal Server so that they can receive

enviro applicable policies and settings.

 standalone user: someone using PGP Whole Disk Encryption for Linux

with no asso

ciated PGP Universal Server. Standalone users establish their

own policies and settings.

 recovery: the process of restoring access to a disk/partition that has been

Note: Versions of PGP Whole Disk Encryption for other platforms support

both a graphical user interface and a command line interface. PGP Whole Disk Encryption for Linux has only a command-line interface.

You enter a valid command at the command prompt and press Enter. PGP Whole Disk Encryption for Linux responds based on what you entered: with success (if you entered a valid command) or with an error message (if you entered an invalid or incorrectly structured command).

All PGP Whole Disk Encryption for Linux commands have a long form: the text "pgpwde", a space, two h appr

Scripting

PGP Whole Disk Encryption for Linux commands can easily be inserted into scripts for automating common tasks, such as encrypting a disk or getting information about an encrypted disk.

PGP Whole Disk Encryption for Linux commands can easily be added to scripts written with scrip

ting languages such as Perl or Python.

WDE-ADMIN Active Directory Group

If you are an administrator of PGP Whole Disk Encryption for Linux clients in a PGP Universal environment and using Active Directory, you can create a special Active Directory group to allow you to run commands on your managed PGP Whole Disk Encryption for Linux clients without knowing the passphrase of a user on the encrypted disk.

This special Active Directory group, which must be called WDE-ADMIN, must be a security gro

up, not a distribution group.

Passphrases

Using the --admin-authorization option is useful for running administrative tasks in

an enterprise.

Refer to the PGP Universal Administrator's Guide for more information about creating and using th

e WDE-ADMIN Active Directory group.

For consistency, all example passphrases in this guide are shown in single quotation marks ('). Putting passphrases between single quotation marks ensures that reserved characters and spaces are interpreted correctly.

If you do not use any reserved characters or spaces in

your passphrases, then

you do not have to enclose them in single quotation marks.

On Windows systems, for example, if you have

a space in a passphrase, you must enclose the passphrase in single or double quotation marks when you enter it. Also, double quotation marks (") as part of the passphrase must be escaped with a preceding double quotation mark.

PGP WDE for Linux User's Guide The Command-Line Interface

For example, if you want to use

Thomas "Stonewall" Jackson

as your passphrase, you would have to enter it as

'Thomas ""Stonewall"" Jackson'

on the command line. You need the quotation marks at the beginning and end for

aces and you need to escape each double quotation mark used in the

the sp

passphrase with another double quotation mark.

Note: If you are having problems entering certain characters in your

passphrases, check the information about how to handle reserved characters for the operating system or shell interpreter you are using.

--interactive

You can use --interactive whenever you could use a command that requires a passphrase be entered on the command line. If you do, you will be prompted to enter a valid passphrase on a separate line.

Using --interactive makes using PGP Whole Disk Encryption for Linux more secure by pre command line. When you use

venting passphrases from being entered in the clear on the

--interactive, the characters you enter are

not displayed.

Note: --interactive is also used in a different way when configuring local

self recovery. See Local Self Recovery for more information.

Before You Encrypt

When you encrypt an entire disk using PGP Whole Disk Encryption for Linux, every sector is encrypted using a symmetric key. This includes all files including operating system files, application files, data files, swap files, free space, and temp files.

On subsequent reboots, PGP Whole Disk Encryption for Linux prompts you for the correc Whole Disk Encryption for Linux-encrypted disk (after you enter the correct passphrase at the PGP BootGuard screen), your files are available. When you shut down your system, the disk is protected against use by others.

Ensure Disk Health

PGP Corporation deliberately takes a conservative stance when encrypting drives, to prevent loss of data. It is not uncommon to encounter Cyclic Redundancy Check (CRC) errors while encrypting a hard disk.

If PGP Whole Disk Encryption for Linux encounters a hard drive or partition with bad sectors, it will, by default, pause the encryption process. This pause allo you to remedy the problem before continuing with the encryption process, thus avoiding potential disk corruption and lost data.

To avoid disruption during encryption, PGP Corporati start with a healthy disk by correcting any disk errors prior to encrypting.

As best practices, before you attempt to

encrypt your drive:

Choose Encryption Options

There are several options you can use during the encryption process itself:

Choosing a Keyboard............................................................................... 27

Your computer boots up in a different way once you use PGP Whole Disk Encryption for Linux to protect the boot disk—or a secondary fixed disk—on your system. On power-up, the first thing you see is the PGP BootGuard log-in screen asking for your passphrase. When you properly authenticate, PGP Whole Disk Encryption for Linux decrypts the disk.

When you use a PGP WDE-encrypted disk, it is decrypted automatically as needed. With most modern computers, after the disk is completely encrypted, there is no noticeable slowdown of your activities.

Once you unlock a disk or partition, its files ar anyone else who can physically use your system. Your files are unlocked until you lock them again by shutting down your computer.

When you shut down a system with an encrypted boot disk or partition, or if you remove an encrypted removabl or partition remain encrypted and fully protected—data is never written to the disk or partition in an unencrypted form. Proper authentication (passphrase, token, or private key) is required to make the files accessible again.

PGP WDE for Linux User's Guide The PGP BootGuard Screen

Authenticating

The PGP BootGuard log-in screen prompts you for the proper passphrase for a protected disk or partition for one of two reasons:

 If your boot disk or partition is protected using PGP Whole Disk Encryption

for Linu

x, you must authenticate correctly for your system to start up. This is required because the operating system files that control system startup are encrypted, and must be decrypted before they can be used to start up the system.

 If a secondary fixed disk or partition is

protected using PGP Whole Disk Encryption for Linux, you can authenticate at startup so that you don’t have to authenticate later when you need to use files on the secondary disk or partition. Because the files on the secondary (non-boot) disk or partition are not required for startup, you are not required to authenticate at startup.

Note: The PGP BootGuard log-in screen accepts the authentication

information from any user configured for an encrypted disk or partition. For example, if you have two users configured for a boot disk or partition and two different users configured for a secondary fixed disk or partition on the same system, any of the four configured users can use their passphrase to authenticate on the PGP BootGuard log-in screen at startup, even the two users configured on the secondary disk or partition.

 To authenticate at the PGP BootGuard log-in screen

1 Start or restart the system that has a disk or pa

rtition protected by PGP Whole Disk Encryption for Linux. On startup, the PGP BootGuard log-in screen is displayed.

2 Type a valid passphrase and press Enter.

Caution: The PGP BootGuard log-in screen assumes you are using one of

the supported keyboard layouts when you type your passphrase. If you used a different keyboard layout to create the passphrase for a disk or partition protected by PGP Whole Disk Encryption for Linux, you could have problems authenticating because the mappings between the keyboard layouts may be different.

To see the characters you type, press Tab before you begin typing.

3 If you ente

If you typed an invalid passphrase, an e

Authenticating if You Have Forgotten Your Passphrase

If you have forgotten your passphrase and cannot authenticate to the PGP BootGuard screen, you can authenticate using local self recovery if you have previously configured it.

Note: Local self recovery must be configured in advance.

Boot Bypass Commands

The boot bypass feature lets you reboot a system one or more times without having to authenticate at the PGP BootGuard screen.

Caution: Using the boot bypass feature weakens the protection provided by

PGP Whole Disk Encryption. Pay extra attention to the physical security of systems when a bypass restart count exists. Use the --remove-bypass command to remove any unnecessary remaining bypass restarts.

Boot bypass is generally used for remote deployment or upgrade scenarios when one or more reboots is required; patch management, for example.

By default, boot bypass is disabled for a system. You must use the --add-

In This Chapter

--add-bypass............................................................................................. 35

--check-bypass ......................................................................................... 37

--remove-bypass ...................................................................................... 37

The --add-bypass command lets you enable one or more bypass restarts for a system.

PGP WDE for Linux User's Guide Boot Bypass Commands

You can set the number of bypass restarts for a system to any value from 0 to 4,294,967,295. Setting the count to 0 (zero) disables bypass restarts. Setting the count from 1 to 4,294,967,295 allows that many bypass restarts, as long as the count is not higher than the preference set on the PGP Universal Server.

In a PGP Universal-managed enviro

nment, the PGP administrator can establish a preference on the PGP Universal Server that limits the number of bypass restarts that can be established using

--add-bypass.

The preference is called wdeMaximumBypassRestarts. Setting the prefe

rence to 0 (zero) disables boot bypass. Setting the preference to a value from 1 to 4,294,967,295 allows that many bypass restarts. If the preference does not exist on the PGP Universal Server, the value is set to 1, allowing one bypass restart for each system.

If you enter a number on the command line that is greater than the preference on the PGP Unive

rsal Server, an error will be returned. The error message does

not display the value configured for the preference.

The usage format is:

pgpwde --add-bypass --disk <number> --count <bypassrestarts> --admin-authorization | --adminpassphrase <phrase>

Where:

 --disk specifies the disk to which the operation applies.

<number> is the disk number on the system.

Where:

 --decrypt specifies that the disk is to be decrypted.  --disk specifies the disk to which the operation applies.  <number> is the disk number on the system.  --admin-authorization specifies that the command is being

perfo

rmed by

a member of the WDE-ADMIN Active Directory group.

 --passphrase specifies the passphrase for an operation.

--encrypt

 <phrase> is the passphrase of an authorized

user on the disk.

 --all specifies that all partitions should be decrypted.  --partition specifies that only the listed partition should be decrypted.  <partnumber> is the partition to be decrypted.

Example:

 pgpwde --decrypt --disk 0 --all --passphrase

"Frodo*1*Baggins22"

This example shows all partitions of a boot disk being decrypted.

The --encrypt command begins the process of whole disk encrypting a disk.

To use the --encrypt command, the drive to be encrypted must be instrumented and h

ave at least one configured user. The --secure command instruments the drive, adds a user, and encrypts the drive using just one command.

Once the encryption process has started, you can stop it using --stop.

Three options are available for encrypting:

 --dedicated-mode: Uses maximum computer power to encrypt faster;

system is less responsive during encryption.

our

 --fast-mode: Skips unused sectors, so encryption of th

e disk is faster.

 --safe-mode: Allows encryption to be resumed without loss of data if

power is lo

st during encryption; encryption takes longer.

The usage format is:

pgpwde --encrypt --disk <number> --passphrase <phrase> | --keyid <keyid> --all --partition <partnumber>

--dedicated-mode --fast-mode --safe-mode

Where:

 --encrypt specifies that the disk is to be encrypted.

--set-background

The --set-background command lets you specify a custom background image for the PGP BootGuard authentication screen.

Custom background images must be created according to the following spec

 XPM files only.  Image size of 640 by 4

ifications:

80.

PGP WDE for Linux User's Guide PGP BootGuard Customization Commands

 Palette of 15 colors only, including black (one color is reserved for fonts).

You do not have to use all 15 colors in the image.

 8-bit RGB only (cannot be

16-bit RGB). You can verify you are using 8 bit by looking at the XPM header using a text editor: 8-bit values appear as #285A83 (one hex triplet), 16-bit values appears as #28285A5A8383 (two hex triplets).

Note: If you specify an image that does not meet these requirements, a

default text-only screen will be used.

Graphics applications that support the XPM file format include Graphic Converter on Mac OS X, GIMP on Mac OS X/FreeBSD and UNIX/LINUX, and the Convert command on Linux.

The new background image will display when the PGP BootGuard authen

tication screen next appears.

The usage format is:

pgpwde --set-background --disk <number> --image <file>

Where:

 --disk specifies the disk to which the operation applies.  <number> is the disk number on the system.  --image specifies the image file to use as the custom background.  <file> is the name of the XPM file.

The --set-sound command lets you enable or disable the use of audio clues for actions that occur during the PGP BootGuard authentication process. Audio clues are disabled by default.

Audio clues can help vision-impaired users more easily navigate the PGP Boot

Guard authentication process.

When enabled, the system will play audible tone combinations during the PGP BootGu

ard authentication process. Each tone combination begins with a middle sound and is followed by either a higher tone, another middle tone, or a lower tone.

The three combinations are:

 Ready for passphrase/pin entry: When the system is first ready for

passph

rase/pin

entry, the middle-middle tone combination plays.

 Successful authentication: If the authentication attempt was successful,

the middle-high tone combination plays. The system then continues

boo

PGP WDE for Linux User's Guide PGP BootGuard Customization Commands

 Unsuccessful authentication: If the authentication attempt was

unsuccessful, the middle-low tone combination plays. The PGP BootGuard authentication screen displays and the passphrase field is cleared for another authentication attempt.

--set-start

The tone combinations cannot be customized; you can only de

cide whether to

enable audio clues or disable them.

Changes will take effect on the next system startup.

The usage format is:

pgpwde --set-sound --disk <number> --beep | --no-beep

Where:

 --disk specifies the disk to which the operation applies.  <number> is the disk number on the system.  --beep enables audio clues.  --no-beep disables audio clues.

Recovery Token

Commands

In PGP Universal-managed environments with the appropriate policy, Whole Disk Recovery Tokens (WDRTs) are created automatically when a disk, partition, or removable disk is whole disk encrypted. They are sent to the PGP Universal Server managing security for the disk or partition when they are created.

WDRTs can be used to access the disk or partitio authentication token is lost.

Once a WDRT is used, it cannot be used ag generated for the system. All new WDRTs are also automatically sent to the PGP Universal Server managing the disk when the new WDRT is created.

Because the first WDRT for a system is created automatically, the only command related to W

 <string> is the WDRT string.

Example:

 pgpwde --new-wdrt --disk 0 --admin-passphrase

'bilbo@baggins44' --recovery-token 'GandalfBilbo+Merry=OneRing'

This example shows a new WDRT being created.

Local Self Recovery

Local self recovery lets you authenticate to PGP BootGuard even if you have forgotten your passphrase.

Note: Local self recovery only works if you configure it before you lose your

passphrase; PGP Corporation recommends configuring it immediately after licensing PGP Whole Disk Encryption for Linux if you plan on using it.

When you configure local self recovery, you create five security questions; three must be answered correctly to authenticate to PGP BootGuard.

Note: If you are using PGP Whole Disk Encryption for Linux in a PGP

Universal Server-managed environment, your PGP Universal Server administrator may have disabled the option for local self recovery. Your administrator may also have specified that local self recovery be configured during enrollment. In this case, you are prompted to enter the security questions as as you set up PGP Whole Disk Encryption for Linux.

The local self recovery commands are:

 --recovery-configure: Configures the local self reco  --recovery-questions: Displays local self recovery questions.  --recovery-verify: Verifies existing local self recovery questions and

--recovery-configure

The --recovery-configure command configures local self recovery.

You can configure the required five questions and answers in either of two ways:

 text files: you create two text files; one text file with five questions, each

on sepa questions, again each on a separate line.

 interactively (--interactive): You will be prompted for five questions

and

You can also use --interactive to have PGP Whole Disk Encryption for Linux interactively prompt for a p on the command line.

Note: Text files and --interactive are mutually exclusive. Use one

method or the other.

assphrase. Simply do not enter a passphrase

You will need to be able to correctly answer three of the five questions if you forget your passphrase and need to authenticate to PGP BootGuard using

--recovery-verify.

The usage format is:

pgpwde --recovery-configure --user <username> -passphrase <phrase> [--disk <disknumber>] [--questionsfile <questions>] [--answers-file <answers>] [--interactive]

Where:

 --recovery-configure specifies that you are configuring local self recovery.  --user spe
