What technique enhances the security of a password by adding random data to it before it's hashed?
Tokenization
Key Stretching
Hashing
Salting
Salting involves adding random data, known as a 'salt', to an input before hashing it. This process prevents against identical inputs producing the same hash (reducing the risks from rainbow table attacks) and improves password security by ensuring that even identical user passwords will result in different hashes.
