Import rainbowcrack from pkgsrc-wip, packaged by David Howland
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. 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.
