/*

* 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.
