About PGP Whole Disk Encryption for Linux

Thank you for using PGP Whole Disk Encryption for Linux, a software product from PGP Corporation that locks down the entire contents of your Linux system using PGP Whole Disk Encryption (WDE) technology.

For more information about PGP WDE, see the:

 PGP Desktop User's Guide  PGP WDE Quick Start Guide  PGP WDE Data Sheet (available via the PGP WDE page on the PGP

PGP Whole Disk Encryption for Linux gives you access to PGP WDE functionality using a command-line interface.

The encryption algorithm used by PGP Whole Disk Encryption for Linux is AES-

256. The hashing algorithm is SHA-1. You cannot change these.

Warning: Once you unlock a disk, its files are available to you—as well as

anyone else who can physically use your system. Your files are unlocked until you lock them again by shutting down your system.

Important Terms

Understanding the following terms will help make it easier to use PGP Whole Disk Encryption for Linux:

Corporation website)

PGP WDE for Linux User's Guide Introduction

 PGP Whole Disk Encryption (PGP WDE): a technology that encrypts the

entire contents of a disk; boot disks, partitions, and non-boot disks such as USB thumb drives can all be whole disk encrypted.

 PGP Whole Disk Encryption for Linux: a software product from PGP

Corporation that brings PGP WDE technology to the Linux platform, allowing you to lock down the entire contents of your Linux system.

 command line: the interface to PGP Whole Disk Encryption for Linux

functionality. All PGP Whole Disk Encryption for Linux commands and options are accessed via the command-line interface.

 passphrase user: a user who can authenticate to an encrypted disk using

a passphrase.

 public-key user: a user who can authenticate to an encrypted disk using

the passphrase to the corresponding private key.

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

properly authenticate.

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

partition table; that is, it is implemented during the startup process before the operating system itself. The instructions in the MBR tells the system how to boot.

 instrument: a part of the process of whole disk encrypting a disk/partition

where the Linux MBR is replaced with the PGPMBR.

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

BootGuard. Once a disk is instrumented, 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 proper authentication for the boot process to continue. If proper authentication is not provided, the boot process will not continue; the operating system will not load 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 encrypted 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.

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

whole disk encrypted but now cannot be decrypted.

The Command-Line

Overview

Interface

This section describes the command-line interface used by PGP Whole Disk Encryption for Linux .

In This Chapter

Overview..................................................................................................11

Scripting...................................................................................................12

Passphrases ............................................................................................12

--interactive ..............................................................................................12

PGP Whole Disk Encryption for Linux uses a command-line interface.

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 hyphens "--", the command name, and options (if appropriate).

For example:

$pgpwde --help [Enter] is the command to display the built-in help information. It has no options. (The command prompt, $ in the above example, and [Enter] will no longer be

shown in examples; only the necessary commands and options will be shown.) A few commands also have a short form: either one hyphen and then a single

letter or two hyphens and two letters. For example:

-h for help instead of --help

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

You can mix long forms and short forms in a single command.

Scripting

Passphrases

Short forms are noted where appropriate.

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 scripting languages such as Perl or Python.

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.

--interactive

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

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.

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

Using --interactive makes using PGP Whole Disk Encryption for Linux more secure by preventing passphrases from being entered in the clear on the command line. When you use --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 correct passphrase. As long as you correctly authenticate to your PGP Whole Disk Encryption for Linux-encrypted disk (after you enter the corre ct passphrase at the PGP BootGuard screen), your files are available. When you shut down your system, the disk is protected against use by others.

Before encrypting your disk with PGP Whole Disk Encryption for Linux, there are some important things to do:

 Ensure the health of the hard disk.  Choose the encryption options to use.  Make sure to maintain power throughout encryption.

In This Chapter

Ensure Disk Health..................................................................................15

Choose Encryption Options.....................................................................16

Maintain Power Throughout Encryption...................................................16

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 allows 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 Corporation recommends that you start with a healthy disk by correcting any disk errors prior to encrypting.

PGP WDE for Linux User's Guide Before You Encrypt

As best practices, before you attempt to encrypt your drive:

 use a third-party scan disk utility that has the ability to perform a low-level

integrity check and repair any inconsistencies with the drive that could lead

to CRC errors.

Choose Encryption Options

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

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

your system is less responsive during encryption.

 --fast-mode: Skips unused sectors, so encryption of the disk is faster.  --safe-mode: Allows encryption to be resumed without loss of data if

power is lost during encryption; encryption takes longer.

Maintain Power Throughout Encryption

Because encryption is a CPU-intensive process, encryption cannot begin on a laptop computer that is running on battery power. The computer must be on AC power. Do not remove the power cord from the system before the encryption process is over.

Regardless of the type of computer you are working with, your system must not lose power, or otherwise shut down unexpectedly, during the encryption process, unless you use the --safe-mode option. Even if you are using the --safe- mode option, it is still better not to lose power during the encryption process.

If loss of power during encryption is a possibility—or if you do not have an uninterruptible power supply for your computer—be sure to use the --safe- mode option.

These options are also described with the --encrypt command.

Overview

The Encryption Process

This section describes the two methods for whole disk encrypting a drive.

In This Chapter

Overview..................................................................................................17

Using --secure..........................................................................................17

Using Individual Commands....................................................................18

To PGP Whole Disk Encrypt a drive requires several things: the drive must be instrumented, there must be at least one authorized user on the drive, and the drive must be encrypted.

There are two ways to PGP Whole Disk Encrypt a drive:

Using --secure

 using a single command, --secure: this one command does all three of

the above actions. It instruments the drive, creates an authorized user, and

encrypts the drive. This command is most useful when you have just

installed PGP Whole Disk Encryption for Linux and thus have not

instrumented any drives, created any authorized users, or encrypted any

drives.

 using multiple commands: for scenarios where you do not need all three

things required to PGP Whole Disk Encrypt at drive, or if you just prefer

using individual commands, you can use --instrument, --add-user,

and finally --encrypt to PGP Whole Disk Encrypt a drive.

The --secure command instruments the drive, creates an authorized user, and encrypts the drive, all using a single command.

Note: PGP Whole Disk Encryption for Linux must be correctly installed and

licensed before you can use --secure.

Refer to Disk Operation for more information about the --secure command.

 To PGP Whole Disk Encrypt a drive using a single command

1 Access a command prompt on your system. 2 Enter the text for the --secure command on a single line.

For example:

pgpwde --secure --disk 0 --username "Alice Cameron" --

passphrase 'Frodo*1*Baggins22' --all --fast-mode

3 Press Enter. PGP Whole Disk Encryption for Linux begins to PGP Whole

Disk Encrypt the drive. You can check the progress of the encryption process using the --status

command. Run the command and check the highwater mark; it will continue to get larger as the encryption process continues.

Using Individual Commands

For scenarios where you do not need to instrument a drive, add a user, and encrypt the drive all at the same time or if you just prefer using individual commands, you can run the three needed commands individually.

The three commands and the order in which you need to run them are:

 --instrument: replaces the Linux MBR with the PGPMBR.  --add-user: adds an authorized user to the drive.  --encrypt: encrypts the drive.

 To PGP Whole Disk Encrypt a drive using individual commands

1 Access a command prompt on your system. 2 Enter the text for the --instrument command on a single line, then press

Enter.

For example:

pgpwde --instrument --disk 0

This example instruments the boot drive. You can use the --status

command to make sure the drive was instrumented.

3 Enter the text for the --add-user command on a single line, then press

Enter.

For example:

pgpwde --add-user --disk 0 --username "Alice Cameron" --

passphrase 'Frodo@Baggins22'

This example adds a user named Alice Cameron to the boot drive. You can

use the --verify-user command to make sure the user was created.

4 Enter the text for the --encrypt command on a single line, then press

Enter.

For example:

pgpwde --encrypt --disk 0 --passphrase 'Frodo@Baggins22'

--all --safe-mode

This example encrypts all partitions of the boot drive in safe mode.

You can check the progress of the encryption process using the --status

command. Run the command and check the highwater mark; it will continue

to get larger as the encryption process continues.

The PGP BootGuard

Overview

Screen

This section describes actions you can take at the PGP BootGuard screen.

In This Chapter

Overview..................................................................................................21

Authenticating..........................................................................................22

Authenticating if You Have Forgotten Your Passphrase.........................23

Choosing a Keyboard ..............................................................................24

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 and opened 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 are available to you—as well as 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 removable disk from the system, all files on the disk 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

On the PGP BootGuard log-in screen you can:

 Authenticate an encrypted boot or secondary disk or partition on the

system.

 View information about the disks or partitions on your system.  Authenticate if you have forgotten your passphrase.  Choose your keyboard layout.

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 Linux, you must authenticate correctly for your system to start up. This is

required because the operating system files that control system sta rtup 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 partition protected by PGP

Whole Disk Encryption for Linux. On startup, the PGP BootGuard log-in

screen is displayed.

Note: If you are using a USB device for two-factor authentication, be sure

the USB device is properly inserted before you start or restart your system.

2 Type a valid passphrase and press Enter.

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

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.

Note: Token authentication in PGP BootGuard requires pressing

Ctrl+Enter instead of just Enter. You may also experience some delay

during the authentication of tokens in PGP BootGuard.

3 If you entered a valid passphrase, the PGP BootGuard log-in screen goes

away and the system boots normally.

If you typed an invalid passphrase, an error message is displayed. Try

typing the passphrase again.

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.

See Local Self Recovery for information about using the command line or a text file to configure the local self recovery questions.

 To authenticate at the PGP BootGuard screen using local self recovery

1 On the PGP BootGuard screen, use the arrow keys to select Forgot

Passphrase in the lower right corner, then press Enter. A new screen

appears, showing the first local self recovery question.

2 Enter the answer to the first question, then press Enter. The second

question appears.

3 Enter the answer to the second question, then press Enter. The third

question appears.

4 Enter the answer to the third question, then press Enter. The fourth

questions appears.

5 Enter the answer to the fourth question, then press Enter. The fifth and last

question appears.

6 Enter the answer to the fifth question, then press Enter.

If you entered three or more of the questions correctly, the PGP BootGuard

screen goes away and the system boots normally.

If you did not enter three or more questions correctly, you are given another

chance.

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

If you subsequently remember your original passphrase, you can continue using it. Using local self recovery does not remove your passphrase.

If you do not believe you will ever remember your original passphrase, you can change your passphrase after authenticating to PGP BootGuard using the

--recovery-change-passphrase command. This means that you do not have to continue using the local self recovery questions to authenticate to PGP BootGuard. Using this command does remove your original passphrase, so it will not work if you remember it later.

Choosing a Keyboard

The PGP BootGuard screen lets you change your keyboard layout.

Note: Different keyboard layouts can have different mappings between

characters, potentially causing problems when you enter your passphrase to authenticate. Select the keyboard layout that most closely maps to the keyboard you are using, then make sure to use that same layout each time you authenticate.

 To select a keyboard layout at the PGP BootGuard screen

1 On the PGP BootGuard screen, use the arrow keys to select Keyboard in

the lower right corner, then press Enter. A list of supported keyboard

layouts is displayed.

2 Use the arrow keys to select the desired keyboard layout, then press Enter.

The text under the list of supported keyboard layouts changes to reflect the

new keyboard layout.

3 Press Tab to move focus to the Go Back command, then press Enter.

This example shows that the system has one disk, Disk 0, with two online

volumes. Disk 0 is the boot disk in most cases.

--info

The --info command provides general status information for the specified disk.

Note: Use the --status command for PGP WDE-specific information about

a disk.

Information you can see about a disk using --info includes:

 model information.  total number of sectors on the disk.

The usage format is:

Show configuration information completed

This example shows the PGP BootGuard information for a boot disk that is

encrypted. An error displays if the disk is not encrypted.

The --status command provides PGP WDE-specific status information for the specified disk.

(Use the --info command for general information about a disk.) Information you can see about a disk using --status includes:

 whether or not the disk is instrumented.  whether or not the disk is whole disk encrypted.  the number of sectors on the disk.

PGP WDE for Linux User's Guide Disk Information Commands

 the highwater mark (the number of encrypted sectors on the disk).

Note: If you are encrypting or decrypting a disk, and you want to check

progress, you can run --status periodically and check the high water mark; this number increases as encryption progresses or decreases as decryption progresses.

The usage format is:

pgpwde --status --disk <number> Where:

 --disk is the option specifying to which disk on the system the information

applies.

 <number> is the disk number on the system.

used for authentication is valid, the disk is encrypted, the total number of

sectors on the disk is 192426569, and the high water mark (the number of

sectors encrypted) is 192426569.

 pgpwde --status --disk 1

Disk disk 1 is not instrumented by bootguard.

Request sent to Disk status was successful

In this example, disk 1 is not instrumented by PGP BootGuard.

Boot Bypass Commands

The Boot Bypass feature lets you reboot a system one time without having to authenticate at the PGP BootGuard screen. Boot Bypass can be set for boot disks only.

When enabled, PGP Whole Disk Encryption for Linux automatically authenticates at the PGP BootGuard screen and boots the system.

Note: You must set up Boot Bypass in advance.

Boot Bypass is generally used for remote deployment or upgrade scenarios when a reboot is required; patch management, for example.

Caution: Boot Bypass bypasses the security of a system. Make sure to use it

appropriately.

The Boot Bypass commands are:

 --add-bypass: Enables the specified disk for Boot Bypass.  --check-bypass: Checks to see if the specified disk is enabled for Boot

Bypass.

 --remove-bypass: Removes Boot Bypass from a disk where it is enabled.

In This Chapter

--add-bypass............................................................................................31

passphrase <phrase>

on the encrypted disk will be used to authenticate.

'bilbo@baggins42'

Remove bypass completed

This example shows the removal of Boot Bypass from a disk.

Disk Operation

The disk operation commands are:

 --decrypt: Decrypts the specified disk.  --encrypt: Encrypts the specified disk.  --resume: Resumes a halted encrypt or decrypt process.  --secure: Encrypts a disk to a specified user and passphrase.  --stop: Halts an encrypt or decrypt process.

In This Chapter

--decrypt...................................................................................................35

--encrypt...................................................................................................36

--resume...................................................................................................37

--secure....................................................................................................38

--stop........................................................................................................39

--decrypt

The --decrypt command starts the process of decrypting an encrypted disk. If the disk is in the process of being encrypted, you need to stop the encryption

process using --stop.

Note: If you are decrypting a disk, and you want to check progress, you can

run --status periodically and check the lowwater and highwater marks.

The usage format is:

pgpwde --decrypt --disk <number> --passphrase <phrase>

--all --partition <partnumber>

PGP WDE for Linux User's Guide Disk Operation

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.  --passphrase specifies the passphrase for an operation.  <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"

--encrypt

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 have 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;

your system is less responsive during encryption.

 --fast-mode: Skips unused sectors, so encryption of the disk is faster.  --safe-mode: Allows encryption to be resumed without loss of data if

power is lost 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.  --disk specifies the disk to which the operation applies.  <number> is the disk number on the system.

PGP WDE for Linux User's Guide Disk Operation

 --passphrase specifies the passphrase for an operation.  <phrase> is the passphrase of an authorized user on the disk.  --keyid specifies a user by key ID for an operation.  <keyid> is the key ID of an authorized user on the disk.  --all specifies that all partitions should be decrypted.  --partition specifies that only the listed partition should be encrypted.  <partnumber> is the partition to be encrypted.  --dedicated-mode specifies that dedicated mode (uses maximum

computer power to encrypt faster) be used in the encryption process.

 --fast-mode specifies that fast mode (skipping unused sectors) be used

in the encryption process.

 --safe-mode specifies that safe mode (encryption can be resumed

without loss of data if power is lost) be used in the encryption process. Example:

 pgpwde --encrypt --disk 0 --passphrase

'Frodo*1*Baggins22' --safe-mode --all

--resume

This example shows encryption of all partitions of a boot disk being started

using safe mode. Authentication is provided by an authorized user.

The --resume command resumes a stopped process, either encrypting or decrypting a disk.

The usage format is:

pgpwde --resume --disk <number> --passphrase <phrase>

PGP WDE for Linux User's Guide Disk Operation

Where:

 --resume specifies that a stopped process is to be resumed.  --disk specifies the disk to which the operation applies.  <number> is the disk number on the system.  --passphrase specifies the passphrase for an operation.  <phrase> is the passphrase of an authorized user on the disk.

Example:

 pgpwde --resume --disk 0 --passphrase 'Frodo@Baggins44'

--secure

This example shows a stopped process being resumed on the boot disk.

The --secure command encrypts a disk to a specified user and passphrase. It does three things that can also be done separately: it instruments the disk,

adds a passphrase user, and encrypts the disk. The usage format is:

pgpwde --secure --disk <number> --username <name> --

passphrase <phrase> --keyid <keyid> --all --partition

<partnumber> --dedicated-mode --fast-mode --safe-mode

Where:

 --secure specifies that: a disk is to be instrumented, a passphrase user

created, and the disk encrypted.

 --disk specifies the disk to which the operation applies.  <number> is the disk number on the system.  --username specifies a passphrase user on the disk is to be created.  <name> is the name of the passphrase user being created.  --passphrase specifies a passphrase is to be created.  <phrase> is the passphrase of the user being added to the disk.  --keyid specifies a user by key ID for an operation.  <keyid> is the key ID of an authorized user on the disk.  --all specifies that all partitions should be encrypted.  --partition specifies that only the listed partition should be encrypted.  <partnumber> is the partition to be encrypted.  --dedicated-mode specifies that dedicated mode (uses maximum

computer power to encrypt faster) be used in the encryption process.

PGP WDE for Linux User's Guide Disk Operation

 --fast-mode specifies that fast mode (skipping unused sectors) be used

in the encryption process.

 --safe-mode specifies that safe mode (encryption can be resumed

without loss of data if power is lost) be used in the encryption process. Example:

 pgpwde --secure --disk 0 --username "Alice Cameron" --

passphrase 'Frodo*1*Baggins22' --all --safe-mode

This example shows a boot disk being secured (instrumented and

encrypted, with a new passphrase user).

--stop

The --stop command stops the current process, either encrypting or decrypting a disk.

The usage format is:

pgpwde --stop --disk <number> Where:

 --stop specifies the current process is to be stopped.  --disk specifies the disk to which the operation applies.  <number> is the disk number on the system.

Example:

 pgpwde --stop --disk 0

This example shows the encryption or decryption process on disk 0 being

stopped.

Disk Management

The disk management commands are:

 --auth: Lets you authenticate to an encrypted disk.  --instrument: Installs PGP WDE configuration information on specified

disk.

 --uninstrument: Removes WDE configuration from specified disk.

In This Chapter

--auth........................................................................................................41

--instrument..............................................................................................42

--uninstrument..........................................................................................42

--auth

The --auth command lets you authenticate to an encrypted disk. The usage format is:

pgpwde --auth --disk <number> --passphrase <phrase> Where:

 --auth specifies you are authenticating to an encrypted disk.  --disk specifies the disk to which the operation applies.  <number> is the disk number on the system.  --passphrase specifies the passphrase for an operation.  <phrase> is the passphrase of an authorized user on the disk.

Example:

 pgpwde --auth --disk 0 --passphrase 'Sam&Gamgee44'

This example shows a user on an encrypted disk authenticating to the boot

disk, disk 0.

PGP WDE for Linux User's Guide Disk Management

--instrument

The --instrument command replaces the Linux MBR with the PGPMBR. Instrumenting the disk or partition is the first step in the process of securing a

disk; it is followed by adding a passphrase user and then encrypting the disk. These three actions can be done individually, in that order, or all at once using the --secure command.

The usage format is:

pgpwde --instrument --disk <number> Where:

 --instrument specifies that a disk or partition is to be instrumented.  --disk specifies the disk to which the operation applies.  <number> is the disk number on the system.

Example:

--uninstrument

 pgpwde --instrument --disk 0

This example shows a boot disk being instrumented.

The --uninstrument command replaces the PGPMBR with the original (saved) Linux MBR. This removes the requirement to authenticate at the PGP BootGuard screen when starting the system.

Uninstrumenting a disk is normally done as part of the decryption process, so this command is not normally used on its own.

Caution: You can only uninstrument a disk that has been instrumented but

nothing else. You cannot uninstrument an encrypted disk.

The usage format is:

pgpwde --uninstrument --disk <number>

PGP WDE for Linux User's Guide Disk Management

Where:

 --uninstrument specifies specifies that a disk or partition is to be

uninstrumented.

 --disk specifies the disk to which the operation applies.  <number> is the disk number on the system.

Example:

 pgpwde --uninstrument --disk 0

This example shows a boot disk being uninstrumented.

User Management

Commands

The user management commands are:

 --add-user: Adds user to disk or group.  --change-passphrase: Changes passphrase of specified user or group.  --change-userdomain: Changes authentication domain of specified user

PGP BootGuard

Customization Commands

PGP Whole Disk Encryption for Linux includes commands for modifying the default PGP BootGuard screen.

The PGP BootGuard customization commands are:

 --set-background: Lets you specify a custom PGP BootGuard screen

background.

 --set-language: Lets you specify a language for the PGP BootGuard

display and keyboard.

 --set-sound: Enables or disables audio prompts on the PGP BootGuard

screen.

 --set-start: Lets you specify a custom PGP BootGuard startup screen

background.

 --set-text: Lets you specify a text message for the PGP BootGuard

authentication screen.

In This Chapter

--set-background......................................................................................51

--set-language..........................................................................................52

--set-sound...............................................................................................53

--set-start..................................................................................................54

--set-text...................................................................................................55

--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 specifications:

 XPM files only.  Image size of 640 by 480.  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.

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

 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 authentication 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.

--set-language

 --image specifies the image file to use as the custom background.  <file> is the name of the XPM file.

Example:

 pgpwde --set-background --disk 0 --image "corplogo.xpm"

This example shows an image file, corplogo.xpm, being set as the

background image for the PGP BootGuard authentication screen.

The --set-language command lets you specify the languages that will be used by PGP BootGuard for display and for the keyboard.

You can specify one language and one display from the list of supported languages. You are not required to use the same language for both.

Options not specified are not changed. So if you specify a new language for text, the existing keyboard setting is not changed. The response to the --set- language command shows both the previous settings and the new settings, for both display and keyboard.

Changes will take effect on the next system startup. The usage format is:

pgpwde --set-language --disk <number> --display <view>

--keyboard <type>

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

Where:

 --disk specifies the disk to which the operation applies.  <number> is the disk number on the system.  --display specifies the language to be used for viewing.  <view> is desired language ID for the display: default (keep existing

language), de, en, es, fr, or jp.

 --keyboard specifies the language to be used for typing text.  <type> is the desired language for the keyboard: default (keep existing

language), de, en, en-gb, es, fr, or jp. Example:

 pgpwde --set-language --disk 0 --display jp --keyboard

Boot language is set to Keyboard=en Display=en

Boot language now set to Keyboard=jp Display=en

This example shows Japanese being specified for both display and

keyboard in PGP BootGuard.

--set-sound

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 BootGuard authentication process.

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

passphrase/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 booting.

 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. The tone combinations cannot be customized; you can only decide whether to

enable audio clues or disable them. Changes will take effect on the next system startup.

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

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.

Example:

 pgpwde --set-sound --disk 0 --beep

Accessibility Sounds set to [ON]

--set-start

This example shows audio clues being enabled.

The --set-start command lets you display a custom startup image for PGP BootGuard that appears before the authentication screen. Press any key to make the startup screen disappear.

Custom startup images must be created according to the following specifications:

 XPM files only.  Image size of 640 by 480.  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). 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 startup image will display on the next system startup (unless Boot Bypass is used).

The usage format is:

pgpwde --set-start --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 startup screen.

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

 <file> is the name of the XPM file.

Example:

 pgpwde --set-start --disk 0 --image "corpsplash.xpm"

This example shows an image file, corpsplash.xpm, being set as the PGP

BootGuard startup image.

--set-text

The --set-text command lets you specify text that will display when the PGP BootGuard screen appears.

You can disable the display of text by entering no text where the message would go.

You can enter one line of text, up to 80 characters (including spaces). The default text is: "Forgot your passphrase? Please contact your IT department or Security Administrator."

Note: Text must go in quotation marks or only the text up to the first space will

display. The quotation marks do not display.

Changes will take effect on the next system startup. The usage format is:

pgpwde --set-text --disk <number> --message <text> Where:

 --disk specifies the disk to which the operation applies.  <number> is the disk number on the system.  --message specifies new text for the PGP BootGuard screen.  <text> is the text you want to display. If left empty, no text will display.

Examples:

 pgpwde --set-text --disk 0 --message "You must change

your login passphrase monthly."

This example shows a new text message for the PGP BootGuard screen.

 pgpwde --set-text --disk 0 --message

This example shows the display of text for the PGP BootGuard screen

being disabled.

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 partition in case the passphrase or authentication token is lost.

Once a WDRT is used, it cannot be used again. A new WDRT must be 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 WDRTs is to create a new WDRT.

The recovery token commands are:

 --new-wdrt: Creates a new WDRT after use.

In This Chapter

--new-wdrt

--new-wdrt................................................................................................57

The --new-wdrt command creates a new WDRT (recovery token) when the previous WDRT has been used.

The usage format is:

pgpwde --new-wdrt --disk <number> --admin-authorization

| --admin-passphrase <phrase> --recovery-token <string>

Where:

 --new-wdrt specifies the creation of a new WDRT.  --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 performed

by a member of the WDE-ADMIN Active Directory group.

PGP WDE for Linux User's Guide Recovery Token Commands

 --admin-passphrase specifies that the passphrase of an authorized user

on the encrypted disk will be used to authenticate the adding of the new

user account.

 <phrase> is the passphrase of an authorized user on the disk.  --recovery-token specifies that a recovery token (WDRT) will be

created to replace the used one.

 <string> is the WDRT string.

Example:

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

'bilbo@baggins44' --recovery-token 'Gandalf-

Bilbo+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 recovery feature.  --recovery-questions: Displays local self recovery questions.  --recovery-verify: Verifies existing local self recovery questions and

answers.

 --recovery-remove: Removes existing local self recovery questions and

answers.

 --recovery-change-passphrase: Changes a lost passphrase.

In This Chapter

--recovery-configure.................................................................................59

--recovery-questions................................................................................61

--recovery-verify.......................................................................................62

--recovery-remove....................................................................................63

--recovery-change-passphrase................................................................64

PGP WDE for Linux User's Guide Local Self Recovery

--recovery-configure

The --recovery-configure command configures local self recovery. You can configure the required five questions and answers in either of two ways:

separate lines, and a second text file with five answers to those questions,

again each on a separate line.

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

and their corresponding answers. You can also use --interactive to have PGP Whole Disk Encryption for

Linux interactively prompt for a passphrase. Simply do not enter a passphrase on the command line.

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

method or the other.

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 descriptions of some options in PGP Whole Disk Encryption for Linux mention that they are "secure," as in "This option is not secure". In this context, "secure" means that the option’s argument is saved in non-pageable memory (when that option is available to applications). Options that are not "secure" are saved in normal system memory.

PGP WDE for Linux User's Guide Options

--admin-passphrase

Specifies that the passphrase being used is that of an authorized user of the encrypted disk.

This option can be shortened to --ap. Example:

 pgpwde --add-user --disk 0 --username "Alice Cameron"

--passphrase 'Frodo@Baggins22' --admin-passphrase

'Sam&Gamgee44' This example shows a new passphrase user being added to a boot disk. The

passphrase of an existing user on the disk is used to authenticate.

--all

--answers-file

Specifies that all partitions should be encrypted. Example:

 pgpwde --encrypt --disk 0 --passphrase 'Frodo*1*Baggins'

--all

This example shows encryption of a boot disk being started. All partitions

are to be encrypted.

Specifies the path to a text file with five answers, each on a new line of the file. Example:

 pgpwde --recovery-configure --user "Alice Cameron"

Overview

Troubleshooting

This section describes how PGP Whole Disk Encryption for Linux can be used to troubleshoot problems you might encounter when whole disk encrypting drive s.

In This Chapter

Overview..................................................................................................81

Encryption Does Not Begin......................................................................81

Encryption Does Not Finish .....................................................................83

Problems at PGP BootGuard...................................................................84

The troubleshooting tips in this appendix assume:

 PGP Whole Disk Encryption for Linux is correctly installed on the system.  The software is licensed to support PGP Whole Disk Encryption for Linux.

Before troubleshoot problems with PGP Whole Disk Encryption for Linux, PGP Corporation recommends checking existing resources for information about the issue you are experiencing:

 The PGP Whole Disk Encryption for Linux Release Notes include the latest

information available about PGP Whole Disk Encryption for Linux, including

system requirements and known incompatibilities.

 The PGP Desktop User's Guide includes more information about how to

prepare a drive for encryption, how to encrypt it, and how to use it after

encryption.

Encryption Does Not Begin

While the vast majority of drives can be encrypted without a problem, on some occasions you may find a drive where the encryption process does not start.

Perform the following steps:

1 Review the PGP Whole Disk Encryption for Linux Release Notes for issues

that could be blocking encryption.

PGP WDE for Linux User's Guide Troubleshooting

Potential issues include unsupported operating systems and software

incompatibilities. If any issues are found, make the appropriate changes and

then attempt encryption again. If encryption still will not begin, you can use PGP Whole Disk Encryption for

Linux to learn more information.

1 First, determine the boot drive on the system using the --enum command.

pgpwde --enum

The response will be something like:

Total number of installed fixed/removable storage

device (excluding floppy and CDROM): 1

Disk 0 has 1 online volumes:

volume C is on partition 2 with offset 80325

Enumerate disks completed

This example shows that the system has one disk, Disk 0, which is drive

letter C and is the boot disk. You now know:

 The boot drive can be whole disk encrypted, as it is Disk 0. Only boot

disks that are Disk 0 can be whole disk encrypted.

 That Disk 0 is the boot disk (which you need to know for subsequent

commands).

2 Next, check the status of the boot drive using the --status command.

pgpwde --status --disk 0

Disk disk 0 is not instrumented by bootguard.

Disk status completed

This example shows the response for a disk that is not whole disk

encrypted; that is, the disk is not instrumented by PGP BootGuard.

If a disk is encrypted or even partially encrypted, the response would be

something like:

pgpwde --status --disk 0

Disk disk 0 is instrumented by bootguard.

Current key is valid.

Whole disk encrypted

Total sectors: 192426569 highwater mark: 192426569

Disk status completed

This response or something similar would mean that the encryption process

started but then stopped again. For information on dealing with a drive

where encryption does not finish, refer to Encryption Does Not Finish.

If the problem continues, you will need to get further assistance.

Support.

Encryption Does Not Finish

Once encryption has started, most drives finish encryption normally. On some occasions, however, the encryption process may stop on its own. The cause is generally a problem with the drive being encrypted.

If the system being encrypted loses power during the process, encryption will automatically stop. Depending on whether or not you were using the Safe Mode option (--safe-mode), you have two options:

 If you were using Safe Mode, simply get the system back up and restart

encryption. It should resume near the point where power was lost.

 If you were not using Safe Mode, get the system back up, decrypt the

portion of the drive that was encrypted, and then restart encryption. The best practice for a drive where encryption stopped automatically is to

decrypt the partially encrypted drive, check it for problems, then start encryption again. Be sure to fully decrypt any drive on which encryption was started before checking it for problems.

Note: Refer to the PGP Desktop User's Guide for extensive information about

preparing a drive for encryption.

If encryption stops before finishing (without losing power), perform the following steps:

1 Decrypt the portion of the drive that was encrypted. 2 When the drive is fully decrypted, check the status of the boot drive using

the --status command.

pgpwde --status --disk 0

Disk disk 0 is not instrumented by bootguard.

Disk status completed

This example shows the response for a disk that has been fully decrypted.

PGP WDE for Linux User's Guide Troubleshooting

If the response to the --status command shows the drive still partially

encrypted, make sure the drive is fully decrypted.

3 Next, check the health of the drive; make the changes necessary to ensure

the health of the drive.

4 Review the PGP Whole Disk Encryption for Linux Release Notes for issues

that could be affecting encryption. If any applicable issues are found, make

the appropriate changes.

5 When all changes have been made, reboot the system. 6 Begin the encryption process again.

Problems at PGP BootGuard

On rare occasions, a drive may successfully encrypt but PGP BootGuard may prevent access to the system.

Most cases involving problems at the PGP BootGuard screen involve entering the passphrase correctly.

It's easy to spot a problem involving entering your passphrase: you enter what you believe is the correct passphrase and press Enter; PGP BootGuard displays an error message instead of giving you access to your system.

If you cannot successfully enter your passphrase at the PGP BootGuard screen, perform the following steps:

1 Carefully re-enter your passphrase. You may have typed it incorrectly.

To see the characters you are typing, press Tab then enter your

passphrase.

2 Make sure Caps Lock is off, unless your passphrase is all capital letters. 3 Make sure you are using the correct keyboard layout. If the wrong keyboard

layout is selected, you may inadvertently be typing the wrong characters.

PGP WDE for Linux User's Guide Troubleshooting

Select Keyboard on the main PGP BootGuard screen and press Enter.

Available keyboard layouts are displayed; the selected keyboard layout is

shown under the list. Select Go Back and press Enter to return to the main

PGP BootGuard screen.

Refer to the PGP Desktop User's Guide for more information about

supported keyboard layouts.

4 If there are other configured users for the drive, try the passphrases of

these users.

5 If you determine that you have forgotten your passphrase and you

configured local self recovery, you can attempt to recover your passphrase.

6 If you are in an enterprise environment, contact your PGP Universal

administrator for instructions. If the problem continues, you will need to get further assistance.
