Create password hash to save in database

const hash = pwdUtilAuth.createPasswordHashWithRandomSalt( password, secret, algorithm );

Create another password hash based on saved hash to compare.

const hashForLogin = pwdUtilAuth.createPasswordHashBasedOnSavedAlgorithmSalt( passwordForLogin, savedPasswordHash, secret );
