ABSTRACT:
A technique for producing a hashed output of an input message according to any number of hash algorithms (e.g. SHA-256, SHA-348, SHA-512) having varying bit widths is described. At least a portion of the input message is stored in a first group of registers each having a bit width equal to a first bit width (e.g. 32 bits). If the selected hash algorithm has a larger bit width (e.g. 64 bits), a remainder of the input message is stored in a second plurality of registers each having a bit width equal to the first bit width. The hashed output is then computed according to the selected hash algorithm.
