What is a Rainbow Table?
A rainbow table is a lookup table offering a time-memory tradeoff used in recovering the plaintext password from a password hash generated by a hash function, often a cryptographic hash function. A common application is to make attacks against hashed passwords feasible. Salt is often employed with hashed passwords to avoid this attack.
