        public static char[] getHash​(java.lang.String algorithm,
                             char[] msg)
        Generate hash in a hex character representation
        Parameters:
        algorithm - message digest algorithm
        msg - message text
        Returns:
        hex hash value in text format
        Throws:
        java.lang.IllegalArgumentException - if specified algorithm is not supported
        See Also:
        for supported algorithms

      • getSaltedHash

        public static char[] getSaltedHash​(java.lang.String algorithm,
                                   char[] salt,
                                   char[] msg)
        Generate salted hash for specified message. Supplied salt is returned as prefix to returned hash.
        Parameters:
        algorithm - message digest algorithm
        salt - digest salt (use empty string for no salt)
        msg - message text
        Returns:
        salted hash using specified salt which is returned as a prefix to the hash
        Throws:
        java.lang.IllegalArgumentException - if specified algorithm is not supported
        See Also:
        for supported hash algorithms

      • getSaltedHash

        public static char[] getSaltedHash​(java.lang.String algorithm,
                                   char[] msg)
        Generate salted hash for specified message using random salt. First 4-characters of returned hash correspond to the salt data.
        Parameters:
        algorithm - message digest algorithm
        msg - message text
        Returns:
        salted hash using randomly generated salt which is returned as a prefix to the hash
        Throws:
        java.lang.IllegalArgumentException - if specified algorithm is not supported
