Important: When encrypting a partition/device within which you intend to create a hidden volume afterwards, leave this option unchecked. Note that Quick Format can only be enabled when encrypting partitions/devices. If you are not sure whether to enable or disable Quick Format, we recommend that you leave this option unchecked. 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 it contains (if the space was not filled with random data beforehand). This means that the new volume will beĮntirely filled with random data. If unchecked, each sector of the new volume will be formatted. For more information, please see the chapter 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 Note that the output of a hash function is never used directly as an encryption key. Header Key Derivation, Salt, and Iteration Count).įor information about the implemented hash algorithms, see the chapter Hash Algorithms. It is also used in deriving the new volume header key and secondary header key (see the section ![]() Please see the section Random Number Generator). 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, However, several items deserve further explanation: Hash AlgorithmĪllows you to select which hash algorithm VeraCrypt will use. The Wizard provides help and information necessary to successfully create a new VeraCrypt volume. The collected data, which should be as random as possible, include your mouse movements, key presses, and other values obtainedįrom the system (for more information, please see the section Random Number Generator). It starts collecting data that will be used in generating the master key, secondary key (XTS mode), and salt, for the new volume. VeraCrypt Volume Creation Wizard should appear. To create a new VeraCrypt file-hosted volume or to encrypt a partition/device (requires administrator privileges), click on ‘Create Volume’ in the main program window.
