    This data includes the message, some padding, and the length of the

    bits), that means that the last segment of the data must have 112 bytes

In order to fill up the message length it must be filled with
    padding that begins with 1 bit followed by all 0 bits. Padding
    must *always* be present, so if the message length is already
