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 tradeoff cryptanalysis attack which originated in Philippe Oechslin's Ophcrack.
[1] Some organizations have made RainbowCrack's rainbow tables available free over the internet.
