A Password Hashing System (PHS) is a method of storing passwords securely, making them difficult for an unauthorized person to crack through brute force or dictionary attacks. A PHS is often referred to as a one-way hash function because the password is not reverse engineered after input, but rather the result is always the same (the hashed password). When entered into a target computer or network, all PHS’s return the same “hash value” which typically cannot be changed using traditional attack methods such as brute force and dictionary attacks.
