Abstract:
     The present invention provides an apparatus and method for performing cryptographic operations on a plurality of input data blocks within a processor. In one embodiment, an apparatus for performing cryptographic operations is provided. The apparatus includes a cryptographic instruction and execution logic. The cryptographic instruction is received by a computing device as part of an instruction flow executing on the computing device, wherein the cryptographic instruction prescribes one of the cryptographic operations. The execution logic is operatively coupled to the cryptographic instruction and executes the one of the cryptographic operations. The one of the cryptographic operations includes indicating whether the one of the cryptographic operations has been interrupted by an interrupting event.
