WebSHA-256: This hashing algorithm is a variant of the SHA2 hashing algorithm, recommended and approved by the National Institute of Standards and Technology (NIST). It generates a 256-bit hash value. Even if it’s 30% slower than the previous algorithms, it’s more complicated, thus, it’s more secure. WebFeb 14, 2016 · To Validate a Password. Retrieve the user's salt and hash from the database. Prepend the salt to the given password and hash it using the same hash function. Compare the hash of the given password with the hash from the database. If they match, the password is correct. Otherwise, the password is incorrect.
