Rainbow Crack is one of the most efficient brute-force attack tools. It is used for cracking hashed passwords by minimizing the time to match the predetermined passwords and the password. This tool uses a rainbow chart, which contains reverse hash values for passwords. The tool will only have to compute the hash value of a password at each attack by referring to the chart. These rainbow charts have been previously generated by many companies. They are available on the internet. The major disadvantage of Rainbow Crack is that the table consumes a lot of storage space.
