In this paper we present a design for a crypto-engine. We shall discuss the design and show the instruction set of this coprocessor and then show how this could be used to implement most of the known encryption algorithms. We will discuss why a coprocessor approach may be a better solution than adoption of specific encryption algorithms which can be broken or decertified.
