![]() RainbowCrack now works on windows and linux. Other hash algorithm can be easily added as required. RainbowCrack 1.2 is more than an instant windows password cracker, multiple hash algorithms(md5, sha1.) are supported which means it is also an instant md5 hash cracker, an instant sha1 hash cracker. RainbowCrack 1.2 support all rainbow tables generated/sorted by earlier versions of the tool. Some tips about charset customization is in the document "Custom charset in RainbowCrack". It is still an interesting reading if you don't have enough processor resource. "Large charset configurations for RainbowCrack" is useful for those want to create rainbow tables for large charset. The RainbowCrack tutorial is an essential reading if you want to make things working. If you have never used the tool before, you can take a glance at some sample outputs of RainbowCrack when cracking some alpha only and alpha numeric windows passwords. Rcrack: no special requirement, performance is maximized when free physical memory size is as large as the rainbow table in use, however, it still works well when memory is lowįirst of all, you can always take Philippe Oechslin's paper as your best reference of the algorithm. Rtsort: 32MB free physical memory at least It may take a long time to precompute the tables, but once the one time precomputation is finished, you will always be able to crack the ciphertext covered by the rainbow tables in seconds. It precompute all possible plaintext - ciphertext pairs in advance and store them in the file so called "rainbow table". While a traditional brute force cracker try all possible plaintexts one by one in cracking time, RainbowCrack works in another way. In short, the RainbowCrack tool is a hash cracker. RainbowCrack is a general propose implementation of Philippe Oechslin's faster time-memory trade-off technique. ![]()
