Here's a test run against one md5crypt hash on one board (4 FPGAs) at Salt length of 8 and password length of 7 to match Hashcat benchmarks. Hashes is capable of password lengths up to 64. We have in JtR have password length limitations of 15 and 39 characters, Some other implementations of md5crypt and phpass "portable hashes" that Which we set as the default and made it configurable in nf. Testing on actual boards, the design works reliably for us at 180 MHz, Per Xilinx tools, this design was supposed to work at 202 MHz. Same as the designs for sha512crypt + Drupal7 and sha256crypt also have. Limit on total loaded hashes as that's handled on host). Including in hybrid modes along with a wordlist coming from host, etc.)Īnd hash comparator (capable of up to 512 loaded hashes per salt no Four times that - meaning 1536 in-flight hashes - per board.Īlso included are on-device candidate password generator (for mask mode, This means 32 soft CPUĬores, 384 hardware threads, 96 MD5 cores, up to 384 in-flight MD5 perįPGA. 32 units fit in one Spartan-6 LX150 FPGA. Three MD5 cores, one soft CPU core, and memory and glue logic form a However, the specific parameters of thoseĬores changed once again: this time, it's 16-bit 12-way SMT CPU coresĪlong with sets of 3 MD5 cores each capable of up to 4 in-flight hashes. The new one for md5crypt + phpass uses specialized soft CPU cores along Similarly to Denis' designs for sha512crypt + Drupal7 and sha256crypt, Knowledge, the very first time md5crypt and phpass "portable hashes" areĭenis wrote a good description of the design with some ASCII diagrams,
Sha256crypt, and Drupal7 hashes on FPGA, this is, to the best of my Also just like our implementations of sha512crypt, So much to compete with GPUs as it is to provide a way to put those FPGAīoards to more uses. Similarly to sha512crypt, sha256crypt, and Drupal7, this addition is not MD5-based "portable hashes", which many popular web apps forced use of Primarily uses bcrypt, it also includes a "last resort fallback" to Now Denis has also added support for md5crypt and for phpass "portable Sha256crypt, and Drupal7 password hash cracking on the old ZTEX 1.15y Subject: md5crypt & phpass password cracking on FPGAĪs many of you are aware, we support descrypt, bcrypt, sha512crypt, Hash Suite - Windows password security audit tool.
