For all administrators that find themselves in the situation where local administrator accounts or passwords from local accounts on a WIndows system are ‘lost’, there is light at the end of the rainbow…

RainbowCrack is a general propose implementation of Philippe Oechslin‘s faster time-memory trade-off technique. In short, the RainbowCrack tool is a hash cracker that can be run from a CD. A traditional brute force cracker try all possible plaintexts one by one in cracking time. It is time consuming to break complex password in this way.

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”. It does take a long time to precompute the tables. But once the one time precomputation is finished, a time-memory trade-off cracker can be hundreds of times faster than a brute force cracker, with the help of precomputed tables.

14 character passwords can be unveiled in just minutes…
