Abstract
A processing system includes a processor to construct an input message comprising a plurality of padding bits and a hardware accelerator, communicatively coupled to the processor, comprising a first plurality of circuits to perform a stage-1 secure hash algorithm (SHA) hash based on the input message, wherein the hardware accelerator comprises a first data path coupled between a first reference node and a first input node of the first plurality of circuits to feed a first padding bit of the plurality of padding bits to the first input node.
