Volumes -> Set Header Key Derivation Algorithm 
This function allows you to re-encrypt a volume header with a header key derived using a different 
PRF function (for example, instead of HMAC-RIPEMD-160 you could use HMAC-Whirlpool). 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. For more

information, see the section 
Header Key Derivation, Salt, and Iteration Count
. 
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
).

System -> Change Password 
Changes the password used for pre-boot authentication (see the chapter 
System Encryption
).
WARNING: Your TrueCrypt Rescue Disk allows you to restore key data if it is damaged. By doing 
so, you also restore the password that was valid when the TrueCrypt Rescue Disk was created. 
Therefore, whenever you change the password, you should destroy your TrueCrypt Rescue Disk 
and create a new one (select 
System
-> 
Create Rescue Disk
). Otherwise, an attacker could 
decrypt your system partition/drive using the old password (if he finds the old TrueCrypt Rescue 
Disk and uses it to restore the key data). See also the chapter 
Security Requirements and 
Precautions
. 
For more information on changing a password, please see the section
