* 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.
