.TH TRUECRACK "3.5" "September 2011" "version 3.5"
.SH NAME
TrueCrack \- Brute-force password cracker for TrueCrypt (Copyrigth) volumes.
.SH SYNOPSIS
.B truecrack
\fI-t truecrypt_file\fR \fI-w passwords_file\fR [\fIOPTION\fR...]
.br
.B truecrack
\fI-t truecrypt_file\fR \fI-c alphabet\fR [\fIOPTION\fR...]
.SH DESCRIPTION
TrueCrack is a brute-force password cracker for TrueCrypt (Copyrigth) volumes. It works on Linux and it is optimized for Nvidia Cuda technology.
.LP
It supports:
.br
- PBKDF2 (defined in PKCS5 v2.0) based on key derivation functions: Ripemd160, Sha512 and Whirlpool.
.br
- XTS block cipher mode for hard disk encryption based on encryption algorithms: AES, SERPENT, TWOFISH.
.br
- File-hosted (container) and Partition/device-hosted.
.br
- Hidden volumes and Backup headers.
.LP
TrueCrack is able to perform a brute-force attack based on:
.br
- Dictionary: read the passwords from a file of words.
.br
- Alphabet: generate all passwords of given length from given alphabet.
.br
.LP
TrueCrack works on gpu and cpu. TrueCrack requires a lots of resources: we suggest a dedicated gpu board.
