WebPepper (cryptography) 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.

WebRfc2898DeriveBytes implements PBKDF2: a function which turns a password (with a salt) into an arbitrary-length sequence of bytes.PBKDF2 is often used for password hashing (i.e. to compute and store a value which is sufficient to verify a password) because it has the needed characteristics for password hashing functions: a salt and configurable slowness. WebMay 6, 2024 · Make sure the salt isn’t too short and do not simply use the usernames of the password as your salts. Salts should be 32 characters or longer in length.
