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.
