Security Tokens and Smart Cards
TrueCrypt can directly use keyfiles stored on a security token or smart
card that complies with the
PKCS #11 (2.0 or later) standard [23] and that allows the user to store a file (data object) on the
token/card. To use such files as TrueCrypt keyfiles, click
Add Token Files
(in the keyfile dialog
window).
Access to a keyfile stored on a security token or smart card is typically protected
by PIN codes,
which can be entered either using a hardware PIN pad or via the TrueCrypt GUI. It can also be
protected by other means, such as fingerprint readers.
In order to allow TrueCrypt to access a security token or smart card, you need to install a
PKCS #11 (2.0 or later) software library for the token or smart card first. Such
a library may be
supplied with the device or it may be available for download from the website of the vendor or other
third parties.
If your security token or smart card does not contain any file (data object) that you could use as a
TrueCrypt keyfile, you can use TrueCrypt to import any file to the token or smart card (if it is
supported by the device). To do so, follow these steps:
1.
In the keyfile dialog window, click
Add Token Files
.
2. If the token or smart card is protected by a PIN, password, or other means (such as a
fingerprint reader), authenticate yourself (for example, by entering the PIN using a
hardware PIN pad).
3. The ‘Security Token Keyfile’ dialog window should appear. In it, click
Import Keyfile to
Token
and then select the file you want to import to the token or smart card.
Note that you can import for example 512-bit keyfiles with random content generated by TrueCrypt
(see
Tools -> Keyfile Generator
below).
To close all opened security token sessions, either select
