Why are you charging so much money for this?
In turn, there is a lot of inefficiency trying to run DES on general purpose processors because most of the operations consist of bit permutations, lookups, and bitwise operations which even when highly optimized (through bitslicing, etc) still don't come close to the efficiency achieved by directly being implemented as transistors or LUTs (in the case of FPGAs). This is great for FPGA and ASIC implementations because it means it doesn't take much space on the chip to build a DES core and therefore we can fit many of them on each chip and run them at high speed.

If our system doesn’t crack your key immediately, it forwards the job on to our brute-force rig which will find the key within a couple days.įrequently Asked Questions Why are FPGAs so much faster?ĭES was originally designed to run in hardware as an ASIC so it's highly optimized toward using the minimal number of transistors. We are able to achieve an average crack time of 25 seconds and a success rate of 99.5%.
We recently released support for running jobs with the plaintext of 1122334455667788 for FREE! We’re able to do this because we built one of the largest publicly available Rainbow Tables ( Time-Memory Tradeoff Attack) for the entire DES keyspace (2 56).

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.
