Title: PADDING FOR CREATING A MESSAGE DIGEST
Abstract:
An instruction to be used to produce a message digest for a message is executed. In execution, a padding state control of the instruction is checked to determine whether padding has been performed for the message. If the checking indicates padding has been performed, a first action is performed; and if the checking indicates padding has not been performed, a second action, different from the first action, is performed.
