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… WebCryptographic algorithm Definition (s): 1. A well-defined computational procedure that takes variable inputs, including a cryptographic key, and produces an output. Source (s): CNSSI 4009-2015 under cryptographic algorithm (crypto-algorithm) 2.

WebNov 16, 2010 · Rainbow tables are constructed of "chains" of a certain length: 100,000 for example. To construct the chain, pick a random seed value. Then apply the hashing and reduction functions to this seed, and its output, and continue iterating 100,000 times. Only the seed and final value are stored. WebMake sure to encrypt all sensitive data at rest. Ensure up-to-date and strong standard algorithms, protocols, and keys are in place; use proper key management.
