Cryptography salts
WebIn cryptography, a pepper is a secret added to an input such as a password during hashing with a cryptographic hash function. This value differs from a salt in that it is not stored alongside a password hash, but rather the pepper is kept separate in some other medium, such as a Hardware Security Module. [1] WebA cryptographic salt is data which is applied during the hashing process in order to eliminate the possibility of the output being looked up in a list of pre-calculated pairs of hashes and their input, known as a rainbow table. In more simple terms, a salt is a bit of additional data which makes your hashes significantly more difficult to crack
