RainbowCrack is one the very popular and classy password and hash cracking tool that works on the Rainbow tables to figure out the real password match. Rainbowcrack isn’t like the simple brute force thing while it works on a series of pre computered tables known as rainbow tables to get one exact match. One of the best advantage of this tool is that it reduces the cracking process time to very extent as compared to the brute force. In the brute force, hash produces all the combination in a form of plain text and then compares it with the password hash to find the match. If it finds a match, you get the password cracked else all the cracked hashes are discarded as a wastage.
