If you are not sure whether to enable or disable Quick Format, we recommend that you leave this option unchecked. It contains (if the space was not filled with random data beforehand).

Quick format is much faster but may be less secure because until the whole volume has been filled with files, it may be possible to tell how much data This means that the new volume will be entirely filled with random data. If unchecked, each sector of the new volume will be formatted. For more information, please see the chapter Encryption Algorithms. Note that the encryption algorithm cannot be changed after the volume is created. This allows you to select the encryption algorithm with which your new volume will be encrypted. For more information, please refer to the chapter Technical Details.

Note that the output of a hash function is never used directly as an encryption key. It is also used in deriving the new volume header key and secondary header key (see the section Header Key Derivation, Salt, and Iteration Count).įor information about the implemented hash algorithms, see the chapter Hash Algorithms. The selected hash algorithm is used by the random number generator (as a pseudorandom mixing function), which generates the master key, secondary key (XTS mode), and salt (for more information, please see the section Random Number Generator). However, several items deserve further explanation: Hash AlgorithmĪllows you to select which hash algorithm TrueCrypt will use. The Wizard provides help and information necessary to successfully create a new TrueCrypt volume. The collected data, which should be as random as possible, include your mouse movements, key presses, and other values obtained from the system (for more information, please see the section Random Number Generator). As soon as the Wizard appears, it starts collecting data that will be used in generating the master key, secondary key (XTS mode), and salt, for the new volume. TrueCrypt Volume Creation Wizard should appear. To create a new TrueCrypt file-hosted volume or to encrypt a partition/device (requires administrator privileges), click on ‘Create Volume’ in the main program window.
