Type password cracking

RainbowCrack is a computer program which generates rainbow tables to be used in password cracking. RainbowCrack differs from "conventional" brute force crackers in that it uses large pre-computed tables called rainbow tables to reduce the length of time needed to crack a password drastically.[1] RainbowCrack was developed by Zhu Shuanglei, and implements an improved time-memory trade-off cryptanalysis attack which originated in Philippe Oechslin's Ophcrack.[1]

Some organizations have made RainbowCrack's rainbow tables available free over the internet.[2]
