Volumes -> Change Volume Password
Allows changing the password of the currently selected TrueCrypt volume (no matter whether the
volume is hidden or standard). Only the header key and the secondary header key (XTS mode) are
changed – the master key remains unchanged. This function re-encrypts the volume header using
a header encryption key derived from a new password. Note that the volume header contains the
master encryption key with which the volume is encrypted. Therefore, the data stored on the
volume will
not
be lost after you use this function (password change will only take a few seconds).
To change a TrueCrypt volume password, click on
Select File
or
Select Device
, then select the
volume, and from the
Volumes
menu select
Change Volume Password
.
Note: For information on how to change a password used for pre-boot authentication, please see
the section
System -> Change Password
.

PKCS-5 PRF
In this field you can select the algorithm that will be used in deriving new volume header
keys (for more information, see the section
Header Key Derivation, Salt, and Iteration
Count
) and in generating the new salt (for more information, see the section
Random
Number Generator
).
Note: When TrueCrypt re-encrypts a volume header, the original volume header is first
overwritten 256 times with random data to prevent adversaries from using techniques such
as magnetic force microscopy or magnetic force scanning tunneling microscopy [17] to
recover the overwritten header (however, see also the chapter
Security Requirements and
Precautions
).
