The difference between Encryption, Hashing and Salting

WebDec 10, 2015 · A cryptographic hash function is an algorithm that takes an arbitrary amount of data input—a credential—and produces a fixed-size output of enciphered text called a hash value, or just “hash.” That enciphered text can then be stored instead of the password itself, and later used to verify the user. WebIn cryptography, salt refers to some random addition of data to an input before hashing to make dictionary attacks more difficult. Modes Of Introduction.

Salt (cryptography) - Wikipedia

WebSalting is the concept of adding random data in the plaintext data (Example: Password) and then creating the hash of that combination this is called salting.... WebAug 25, 2010 · The purpose of salting is to defeat a dictionary attack. Instead of creating a dictionary of hashed passwords and then simply looking for matches all over the place, you force the attacker to recompute all the hashes for each unique salt.
