RainbowCrack v1.3 available
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.
Changes in version 1.3
- Multicore processor support
Earlier versions will only use one core on a multicore processor system. - Overlapped harddisk read and computation
RainbowCrack 1.3 can do computation and load rainbow tables from harddisk concurrently. - Improved hash algorithm performance of NTLM and MD5
- Fully backward compatible with existing rainbow tables generated by earlier versions of RainbowCrack
RainbowCrack 1.3 use same rainbow table format as earlier versions. - Other enhancements
