Rainbow Table

A precomputed lookup table that maps password hashes back to their plaintext values. Attackers use rainbow tables to crack hashed passwords without brute-forcing each one individually. The table trades storage space for computation time. Salted hashes defeat rainbow tables because each salt creates a unique hash.
