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.
Understanding rainbow tables is essential for cybersecurity professionals who manage authentication systems. Penetration testers use rainbow tables and tools like Ophcrack during password audits. Security engineers must ensure all password storage uses salted hashing algorithms (bcrypt, Argon2). This concept appears on CompTIA Security+, CEH, and CISSP exams.
