+/*
+ * 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.
