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.{{cite web|url=http://www.antsight.com/zsl/rainbowcrack/#Documentation |title=Project RainbowCrack = documentation |accessdate=2008-09-18 |url-status=dead |archiveurl=https://web.archive.org/web/20080705140750/http://www.antsight.com/zsl/rainbowcrack |archivedate=July 5, 2008 }} RainbowCrack was developed by Zhu Shuanglei, and implements an improved time–memory tradeoff cryptanalysis attack which originated in Philippe Oechslin's Ophcrack.

Some organizations have made RainbowCrack's rainbow tables available free over the internet.{{cite web |url=http://www.darknet.org.uk/2006/02/password-cracking-with-rainbowcrack-and-rainbow-tables/ |title= Password Cracking with Rainbowcrack and Rainbow Tables |date= 27 February 2006 |accessdate=2008-09-18}}
