WebAug 30, 2014 · The Rainbow table is optimized for hashes and passwords, and thus achieves great space optimization while still maintaining good look-up speed. But in essence, it's just a dictionary. When an attacker steals a long list of password hashes from you, he can quickly check if any of them are in the Rainbow Table. WebFeb 13, 2024 · A rainbow table works by comparing the hashes in the rainbow table with the hashes of the passwords the attacker is trying to crack. If the hashes match, the attacker can then determine the plain-text version of the password. Rainbow tables are typically used in combination with a password-cracking tool such as John the Ripper.
