When FPGAs attack hashes
This entry was posted in encryption, FPGA, techniques and tagged FPGA, hash cracking.
What could you do with an array of 15 FPGAs? Why not attack hashes!
NSA@home is a fast FPGA-based SHA-1 and MD5 bruteforce cracker. It is capable of searching the full 8-character keyspace (from a 64-character set) in about a day in the current configuration for 800 hashes concurrently, using about 240W of power. The minimum hardware used was an array of 15 Virtex-II Pro (XC2VP20) FPGAs in 3 identical sets of 5. Their website contains a complete description of this interesting and complex use of FPGAs.
