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