To configure common volume encryption parameters within a user group:
1. Click User Groups on the main menu.
2. Click the checkbox next to a user group to select it and then click Configure.
3. On the User Group Configurations window, click Group Volume Settings.
4. The Group TrueCrypt Settings (New) window appears (Figure 47), showing the
following fields:
o Group Name: Identifier of the user group, shown to remind the IT administrator
of the user group for which the encrypted volume is being configured.
o Encryption Algorithm: Algorithm used for encryption of the volume contents.
Available options are:
− AES (default)
− Serpent
− Twofish
− AES-Twofish
− AES-Twofish-Serpent
− Serpent-AES
− Serpent-Twofish-AES
− Twofish-Serpent
o Hash Algorithm: Algorithm used for random generation of the volume master
key. Available options are:
− RIPEMD-160 (default)
− SHA-1
− Whirlpool
o File Format: Type of file system for the encrypted volume. Available options
are:
− FAT (default)
− NTFS (this option does not work for end users that do not have
administrator privileges on their laptops).
Note: Windows XP supports NTFS. Earlier Windows versions and Linux support
FAT.
5. Click Save to save the TrueCrypt settings for the user group.
Note: The values of the user group parameters for TrueCrypt are not retroactively
applied. When one or more user group values change, only the encrypted volumes
that are created after the change reflect the new values.
Note: Since every user group parameter for TrueCrypt has an assigned default value,
the configuration of the user group parameters for TrueCrypt is only necessary when
one or more of those values requires modification.
