Rainbow Tables Hash Cracker - RainbowCrack
RainbowCrack uses time-memory tradeoff algorithm to crack hashes. It differs from the hash crackers that use brute force algorithm. A brute force hash cracker generate all possible plain-texts and compute the corresponding hashes on the fly, then compare the hashes with the hash to be cracked. Once a match is found, the plain-text is found.
RainbowCrack is a general propose implementation of Philippe Oechslin’s faster time-memory trade-off technique. It crack hashes with rainbow tables. RainbowCrack uses time-memory trade-off algorithm to crack hashes. It differs from brute force hash crackers.
A brute force hash cracker generate all possible plain-texts and compute the corresponding hashes on the fly, then compare the hashes with the hash to be cracked. Once a match is found, the plain-text is found. If all possible plain-texts are tested and no match is found, the plaintext is not found. With this type of hash cracking, all intermediate computation results are discarded.
A time-memory trade-off hash cracker need a pre-computation stage, at the time all plaintext/hash pairs within the selected hash algorithm, charset, plain-text length are computed and results are stored in files called rainbow table. It is time consuming to do this kind of computation. But once the one time pre-computation is finished, hashes stored in the table can be cracked with much better performance than a brute force cracker.
In this project, we focus on the development of optimized time-memory trade-off implementation. GPU acceleration is another key feature of RainbowCrack software. By offloading most runtime computation to NVIDIA GPU, overall hash cracking performance can be improved further.
