Tools -> Keyfile Generator
You can use this function to generate a file with random content, which you can use as a keyfile
(recommended). This function uses the TrueCrypt Random Number Generator. Note that the
resulting file size is always 64 bytes (i.e., 512 bits), which is also the maximum possible TrueCrypt
password length.
Settings -> Default Keyfiles
Use this function to set default keyfiles and/or default keyfile search paths. This function is
particularly useful if you, for example, store keyfiles on a USB memory stick that you carry with
you. You can add its drive letter to the default keyfile configuration. To do so, click
Add Path
,
browse to the drive letter assigned to the USB memory stick, and click
OK
. Now each time you
mount a volume (and if
Use keyfiles
is checked in the password dialog), TrueCrypt will scan the
path and use all files that it finds there as keyfiles.

WARNING: When you add a folder (as opposed to a file) to your default keyfile list, only the
path is remembered, not the filenames! This means e.g. that if you create a new file in the
folder or if you copy an additional file to the folder, then all volumes that used keyfiles from
the folder will be impossible to mount (until you remove the newly added file from the
folder).
IMPORTANT: Note that when you set default keyfiles and/or default keyfile search paths, the
filenames and paths are saved unencrypted in the file
Default Keyfiles.xml
. For more information,
please see the chapter TrueCrypt System Files & Application Data.
