In 1998 the Electronic Frontier Foundation built the EFF DES Cracker . It cost around $250,000 and involved making 1,856 custom chips and 29 circuit boards, all housed in 6 chassis, and took around 9 days to exhaust the keyspace. Today, with the advent of Field Programmable Gate Arrays (FPGAs) , we’ve built a system with 48 Virtex-6 LX240Ts which can exhaust the keyspace in around 26 hours, and have provided it for the research community to use. Our hope is that this will better demonstrate the insecurity o

Behind crack.sh is a system with 48 Xilinx Virtex-6 LX240T FPGAs . Each FPGA contains a design with 40 fully pipelined DES cores running at 400MHz for a total of 16,000,000,000 keys/sec per FPGA, or 768,000,000,000 keys/sec for the whole system. This means that it can exhaustively search the entire 56-bit DES keyspace in:
