Examples of javax.crypto.Mac.update()

javax.crypto.Mac.update()
Updates this {@code Mac} instance with the specified byte. @param input the byte @throws IllegalStateException if this MAC is not initialized.

        //
        // standard DAC - zero IV
        //
        mac.init(key);


        mac.update(input, 0, input.length);


        byte[] ref = mac.doFinal();


        for (int i = 0; i != aliases.length; i++)
