![]() This means that it can exhaustively search the entire 56-bit DES keyspace in:Ģ 56 / 768,000,000,000 = ~26 hoursFor comparison, the EFF DES Cracker had 29 boards x 64 chips each = 1,856 chips total, each chip did around 48,000,000 keys/sec for a total system speed of 90,000,000,000 keys/sec:Ģ 56 / 90,000,000,000 = ~9.2 daysTo crack a key in the same amount of time as our system (26 hours) with other modern processors, you would need around: 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. Behind crack.sh is a system with 48 Xilinx Virtex-6 LX240T FPGAs.
