A rainbow table is a precomputed table for caching the outputs of a cryptographic hash function, usually for cracking password hashes. Passwords are typically stored not in plain text form, but as hash values. If such a database of hashed passwords falls into the hands of an attacker, they can use a precomputed rainbow table to recover the plaintext passwords. A common defense against this attack is to compute the hashes using a key derivation function that adds a "salt" to e… WebIts purpose is to make pre-computation based attacks unhelpful. If your password is stored with a unique salt then any pre-computed password-hash table targeting unsalted password hashes or targeting an account with a different salt will … WebSep 11, 2024 · What is a cryptographic lookup table? – Paul Uszak Sep 11, 2024 at 21:21 Add a comment 1 Answer Sorted by: 3 This is a very / too generic question: Q1: What size … iop beach rules
