When FPGAs attack hashes

Posted on Wednesday, December 22nd, 2010 in encryption, FPGA, techniques by the machinegeek


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.
