- /* 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.
