    Public Struct Hmac

    HMAC (RFC 2104) of data with key, of any length: a MAC as long as its hash, which only who has the key can make. Check one with ConstantTimeEquals.

    Examples

    Local message = "The quick brown fox jumps over the lazy dog"
Local mac = Hmac.Sha256("key".Bytes, message)
Expect(Hex.Encode(mac) == "f7bc83f430538424b13298e6aa6fb143ef4d59a14946175997479dbc2d1a3cd8")
// A MAC that came with a message is checked without telling where they differ.
Expect(ConstantTimeEquals(mac, Hmac.Sha256("key".Bytes, message)))
