TrueCrypt brute-force password cracker - TrueCrack

TrueCrack is a brute-force password cracker for TrueCrypt volume files. It works on Linux and it is optimized for Nvidia Cuda technology

Algorithms:

ºPBKDF2 (defined in PKCS5 v2.0) is based on RIPEMD160 Key derivation function.
ºXTS block cipher mode for hard disk encryption based on AES.


TrueCrypt brute-force password cracker:

ºDictionary attack: reads the passwords from a file of only words (one password for line).
ºCharset attack: generates the passwords from a set of symbols defined from the user (for example: all possible strings of n characters from the charset “abc” ).


Performance

The execution time of TrueCrack for a dictionary attack is (average word length 10 characters):

        CPU  3.00GHz   GTX650    GTX680
1000     0m  12.031s 0m  3.771s 0m 2.693s
10000    2m   0.421s 0m 15.893s 0m 5.628s
100000  20m   3.811s 2m 20.379s 0m 37.610s


Dictionary attack:

truecrack -t truecrypt_file -w passwords_file [-k ripemd160 | -k sha512 | -k whirlpool] [-e aes | -e serpent | -e twofish] [-a blocks] [-b] [-H] [-r number]


Alphabet attack:

truecrack -t truecrypt_file -c alphabet [-s minlength] -m maxlength [-k ripemd160 | -k sha512 | -k whirlpool] [-e aes | -e serpent | -e twofish] [-a blocks] [-b] [-H] [-r number]


Usage

-h --help Display this information.
-t --truecrypt <truecrypt_file> Truecrypt volume file.
-k --key <ripemd160 | sha512 | whirlpool> Key derivation function (default ripemd160).
-e --encryption <aes | serpent | twofish> Encryption algorithm (default aes).
-a --aggressive <blocks> Number of parallel computations (board dependent).
-w --wordlist <wordlist_file> File of words, for Dictionary attack.
-c --charset <alphabet> Alphabet generator, for Alphabet attack.
-m --maxlength <maxlength> Maximum length of passwords, for Alphabet attack.
-s --startlength <minlength> Starting length of passwords, for Alphabet attack (default 1).
-r --restore <number> Restore the computation.
-b --backup Backup header instead of volume header.
-H --hidden Hidden Truecrypt volume.
-v --verbose Show verbose messages.


How To Install

cd truecrack
