If for some reason a key isn't found, crack.sh will immediately refund your payment, fix any problem in its system that made it not find the key, and deliver the key to you once it's fixed. Known Plaintext jobs take more time because we always have to go through 100% of the keyspace, whereas MSCHAPv2 only needs to go through ~70% of the keyspace on average before finding both K1 and K2 keys.Ĭrack.sh guarantees that it will 100% produce a working key for jobs submitted.

Why is it more expensive to crack a Known Plaintext job than MSCHAPv2?
In turn, many researchers use this service and aren't necessarily on tight deadlines and instead would like to save some money, for that reason we have a super low-cost option. We understand that some people are possibly using this service to perform security audits and require results a little quicker, for that reason we're offering an option to pay extra to get your job handled faster. What's the difference between the ASAP! and Take Your Time payment options? 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 can also help out by presenting your research at one of the conferences that we organize :-). In that case, it's a great deal! How else can I help! 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 sustainable manner. It actually isn't that expensive when compared to the cost of cracking DES in the cloud or with GPUs. 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.
