TrueCrack: A Brute force Password Cracker Tool



TrueCrack is a brute-force password cracker for TrueCrypt (Copyrigth) volume files. It works on Linux and it is optimized with Nvidia Cuda technology. 
It works with cripted volumes with the following algorithms:

  • PBKDF2 (defined in PKCS5 v2.0) based on RIPEMD160 Key derivation function.

  • XTS block cipher mode of operation used for hard disk encryption based on AES.

password cracker

TrueCrack can work in two different modes of use:

  • Dictionary attack: read the passwords from a file of words (one password for line).

  • Charset attack: generate the passwords from a charset of symbols defined by the user (for example: all possible strings of n characters from the charset "abc" ).

HOW TO RUN?

Dictionary attack from a wordlist file:
./truecrack -t TRUECRYPT_VOLUME -w WORDLIST_FILE -b 1024
Charset attack from an alphabet (ex. abc) with the maximum length(32) for single word: 
./truecrack -t TRUECRYPT_VOLUME -c abc -m 32 -b 1024

EXECUTION OPTIONS

Note: the blocksize argument is directly proportional to the number of parallel cuda grid blocks and the number of password computed. A value 10 to blocksize parameter means that there are 10 cuda blocks running in parallel; each block checks and verifies one single password. So 10 blocks mean 10 password computed in parallel. This value is set by default to the number of cores of the current nvidia board (the maximum is 65536 for 1.x and 2.x cuda architectures); if the GPU is disable, blocksize is set to 1024 by default.

--help

Display the usage information.

-t

--truecrypt FILE

Truecrypt volume file.

-w

--wordlist FILE

Wordlist mode, read words from FILE.

-m

--maxlength INT

Charset mode, max length of words generated.

-c

--charset STRING

Charset mode, create words from charset STRING.

-b

--blocksize INT

Block size of words parallel computed.

-v

HOW TO COMPILE?

TrueCrack can work on CPU or GPU modes.
If you want the Cuda optimization, you set the GPU variable on true:
make GPU=true 
Else if you want use only the CPU resource, you set the GPU variable on false:
make GPU=false 
Make sure that you have correctly install and configure nvidia cuda framework in your system. You can find a brief guide in the Below link.
