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. RainbowCrack was developed by Zhu Shuanglei, and implements an improved time-memory trade-off cryptanalysis attack which originated in Philippe Oechslin's Ophcrack.
Some organizations have made RainbowCrack's rainbow tables available free over the internet.

“You must be wise, in order to sniff out and weigh these mighty books, and swift in the hunt and brave in the battle; then, by careful reading and frequent reflection, crack open the bone and suck out the substantific marrow.”
