Crack.sh Website Review

it cost around $250,000 and involved making 1,856 custom chips and 29 circuit boards, all housed in 6 chas*is, and took around 9 days to exhaust the keyspace. today, with the advent of field programmable gate arrays (fpgas) it for the research community to use. our hope is that this will better demonstrate the insecurity of des and move people to adopt we built one of the largest publicly available rainbow tables (time-memory tradeoff attack time of 25 seconds and a success rate of 99.5%. 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.. 99.5% success rate frequently asked questions why are fpgas so much faster? des was originally designed to run in hardware as an asic so it's highly optimized toward using the minimal number of transistors. 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. 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 why are you charging so much money for this? it actually isn't that expensive when compared to the cost of cracking des in the cloud or with gpus. the system that you're renting time on is over $100k in specialized fpga hardware and costs money to operate, maintain, cool, and power and we're just charging enough to maintain the system and be able to offer it to the research community in a in that case, it's a great deal! how else can i help! please let us know what projects your working on! the main reason why this site exists is so we can see what else out there is still using des and demonstrate to the community that it isn't secure anymore! you
