whitepixel - GPU-accelerated password hash auditing

[ Download whitepixel-2.tar.bz2 ] [ older versions ] [ changelog ] [ 2010-12-14: whitepixel v2 +15% faster than v1 ]

Whitepixel is an open source (GPLv3) GPU-accelerated password hash auditing software for AMD/ATI graphics cards. It serves the needs of law enforcement agencies specialized in high-tech crime and penetration testers. It is currently the world's fastest single-hash MD5 brute forcer: whitepixel achieves 33.1 billion password/sec on 4 x AMD Radeon HD 5970 (see detailed hardware description).

For AMD Radeon HD 5000 series and above
Multi-GPU support (tested with 8 GPUs)
Best MD5 implementation: bitalign IL instruction, BFI_INT native instruction, 18-step MD5 reversing
Linux support only
Open source: GPLv3
Basic configurable charsets

Usage

Usage: ./whitepixel [OPTION]... [<hash>]

Main arguments:
  -c <charset>    Generate candidate passwords using the specified charset
                  which can be:
                    lower  Lowercase
                    upper  Uppercase
                    digit  Digits
                    print  Printable ASCII characters and space [0x20-0x7e]
                    all    All bytes [0x00-0xff]
                  (default: lower)
  -l <length>     Attack passwords of this length (default 5)
  <hash>          MD5 hash to attack (default 00...00)

Other arguments:
  -d <tgt>        Show disassembled kernel for given target and exit
                  (<tgt> is the numerical CAL_TARGET_* value)
  -e              Enable experimental BFI_INT instructions for higher
                  performance (default disabled)
  -g <nr-gpus>    Only use first <nr-gpus> GPU devices (default all)
  -h              Print this help
  -i <iterations> Number of iterations of the main brute forcing loop
                  (default depends on charset)
  -t <nr-threads> Number of threads to run per SIMD (default 256)
  -u              Run internal unit tests and exit
  -v              Verbose mode (-vv for very verbose)
