1280304Sjkim/* 2280304Sjkim * This header declares the necessary definitions for using the 3280304Sjkim * exponentiation acceleration capabilities of Atalla cards. The only 4280304Sjkim * cryptographic operation is performed by "ASI_RSAPrivateKeyOpFn" and this 5280304Sjkim * takes a structure that defines an "RSA private key". However, it is really 6280304Sjkim * only performing a regular mod_exp using the supplied modulus and exponent 7280304Sjkim * - no CRT form is being used. Hence, it is a generic mod_exp function in 8280304Sjkim * disguise, and we use it as such. Thanks to the people at Atalla for 9280304Sjkim * letting me know these definitions are fine and that they can be reproduced 10280304Sjkim * here.
