/* This header declares the necessary definitions for using the exponentiation
* acceleration capabilities of Atalla cards. The only cryptographic operation
* is performed by "ASI_RSAPrivateKeyOpFn" and this takes a structure that
* defines an "RSA private key". However, it is really only performing a
* regular mod_exp using the supplied modulus and exponent - no CRT form is
* being used. Hence, it is a generic mod_exp function in disguise, and we use
* it as such.
*
* Thanks to the people at Atalla for letting me know these definitions are
* fine and that they can be reproduced here.
*
* Geoff.
