A precomputed table that contains word lists like dictionary files, brute force lists, and their hash values is known as what?

• A. Dictionary Attack
• B. rtgen
• C. Rainbow Table
• D. RainbowCrack

Answer: (C)

Rainbow table refers to a precomputed table that stores a huge collection of candidate passwords and their corresponding hash values. By hashing a target password and looking up the result in this table, an attacker can quickly recover the original password without having to hash each guess on the fly. The table often combines dictionary-style wordlists with brute-force candidates, mapping each to its hash, which speeds up password cracking dramatically. The other options describe related ideas but not the exact object: a dictionary attack is the method of guessing passwords from a wordlist, rtgen is a tool used to generate rainbow tables, and RainbowCrack is software that uses rainbow tables to crack hashes.
