Fast FPGA-based SHA-1 and MD5 bruteforce cracker
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.
The cracker is built out of surplus Grass Valley HD video transform boards, scrapped by GV because of defects. A useful tool was developed to assist the board reverse-engineering effort.
