You are trading speed for memory and disk space, the Rainbow Tables can be VERY large, although Rainbow Table attacks are very effective.īe warned though, Rainbow tables can be defeated by salted hashes, if the hashes are not salted however and you have the correct table, a complex password can be cracked in a few minutes rather than a few weeks or months with traditional brute forcing techniques. The idea of time-memory trade-off is to do all cracking time computation in advance and store the result in files so called “rainbow table”.īasically, these types of password crackers are working with pre-calculated hashes of ALL passwords available within a certain character space, be that a-z or a-zA-z or a-zA-Z0-9 etc. It is time-consuming to break complex password in this way. A traditional brute force cracker tries all possible plaintexts one by one in cracking time. In short, the RainbowCrack tool is a hash cracker.

This improved technique has been studied extensively but no new optimisations have been published ever since. This technique was improved by Rivest before 1982 with the introduction of distinguished points which drastically reduces the number of memory lookups during cryptanalysis. In 1980 Martin Hellman described a cryptanalytic time-memory trade-off which reduces the time of cryptanalysis by using precalculated data stored in memory.
