    public static final HmacAlgorithms HMAC_MD5
    The HmacMD5 Message Authentication Code (MAC) algorithm specified in RFC 2104 and RFC 1321.

    Every implementation of the Java platform is required to support this standard MAC algorithm.

  - ### HMAC_SHA_1

    public static final HmacAlgorithms HMAC_SHA_1
    The HmacSHA1 Message Authentication Code (MAC) algorithm specified in RFC 2104 and FIPS PUB 180-2.

- ## Method Details

  - ### values

    public static HmacAlgorithms[] values()
    Returns an array containing the constants of this enum type, in the order they are declared.
    Returns:
      an array containing the constants of this enum type, in the order they are declared

  - ### valueOf

    public static HmacAlgorithms valueOf(String name)
    Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)
    Parameters:
      `name` - the name of the enum constant to be returned.
    Returns:
      the enum constant with the specified name
    Throws:
      `IllegalArgumentException` - if this enum type has no constant with the specified name
