1. WHAT TrueCrack IS? TrueCrack is a brute-force password cracker for TrueCrypt (Copyrigth) volumes. It works on Linux and it is optimized for Nvidia Cuda technology. It supports:

• PBKDF2 (defined in PKCS5 v2.0) based on key derivation functions: Ripemd160, Sha512 and Whirlpool.
• XTS block cipher mode for hard disk encryption based on encryption algorithms: AES, SERPENT, TWOFISH.
• File-hosted (container) and Partition/device-hosted.
• Hidden volumes and Backup headers. TrueCrack is able to perform a brute-force attack based on:
• Dictionary: read the passwords from a file of words.
• Alphabet: generate all passwords of given length from given alphabet. TrueCrack works on gpu and cpu. TrueCrack requires a lots of resources: we suggest a dedicated gpu board.

2. 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 20 m3.811s 2m 20.379s 0m 37.610s

3. HOW TO RUN? 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 [-p string] [-k ripemd160 | -k sha512 | -k whirlpool] [-e aes | -e serpent | -e twofish] [-a blocks] [-b] [-H] [-r number]

4. HOW TO 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). -p --prefix <string> Prefix the first part of the password, for Alphabet attack. -r --restore <number> Restore the computation. -b --backup Backup header instead of volume header. -H --hidden Hidden Truecrypt volume. -v --verbose Show verbose messages.

5. HOW TO CONFIGURE? ./configure --enable-debug : enable nVidia CUDA debug mode [default=no] --enable-cpu : disable cuda nvidia GPU and use CPU [default=no] --with-cuda=PATH : prefix where cuda is installed [default=auto]

6. HOW TO INSTALL? cd truecrack ./configure make sudo make install
