+/* 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.
