Salt in Cryptography Definition: A cryptographic salt is a unique random value added before hashing a password to defeat rainbow tables and force per-hash cracking.
In cryptography, a salt is a unique random value added to a password before it is hashed, ensuring that identical passwords produce different hash outputs. Salting defeats precomputed attacks such as rainbow tables and forces an attacker to crack each hash individually. Salts are stored alongside the hash and are typically used with slow, adaptive password-hashing functions like bcrypt, scrypt, or Argon2.
Salt in Cryptography is one of the topics you'll master in the Security+ Boot Camp.
