In 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]
Typically, a unique salt is randomly generated for each password. The salt and the password (or its version after key stretching) are concatenated and fed to a cryptographic hash function, and the output hash value is then stored with the salt in a database. The salt does not need to be encrypted, because knowing the salt would not help the ...
To solve this problem, they use SCRAM, where Bob can store his password in a salted format, using PBKDF2. During login, Bob sends Alice his salt and the iteration count of the PBKDF2 algorithm, and then Alice uses these to calculate the hashed password that Bob has in his database. All further calculations in SCRAM base on this value which both ...
In cryptanalysis and computer security, password cracking is the process of guessing passwords [1] protecting a computer system.A common approach (brute-force attack) is to repeatedly try guesses for the password and to check them against an available cryptographic hash of the password. [2]
Pepper systems are controversial, however it is still necessary to explain their use. [31] A pepper is a value that is added to a hashed password that has been salted. [34] This pepper is often unique to one website or service, and it is important to note that the same pepper is usually added to all passwords saved in a database. [35]

A main encryption/decryption key is derived from user's password by PBKDF2 function. [2] Particular data binary large objects can be encrypted in a way that salt is added and/or an external user-prompted password (aka "Strong Key Protection") is required. The use of a salt is a per-implementation option – i.e. under the control of the ...
