   1 /* This header declares the necessary definitions for using the exponentiation
   2  * acceleration capabilities of Atalla cards. The only cryptographic operation
   3  * is performed by "ASI_RSAPrivateKeyOpFn" and this takes a structure that
   4  * defines an "RSA private key". However, it is really only performing a
   5  * regular mod_exp using the supplied modulus and exponent - no CRT form is
   6  * being used. Hence, it is a generic mod_exp function in disguise, and we use
   7  * it as such.
   8  *
   9  * Thanks to the people at Atalla for letting me know these definitions are
  10  * fine and that they can be reproduced here.
  11  *
  12  * Geoff.
