* Message digest routines
*/
/*
* The following are the possible returned values common to all the routines
* below. The applicability of some of these return values depends on the
* presence of the arguments.
*
* CRYPTO_SUCCESS: The operation completed successfully.
* CRYPTO_QUEUED: A request was submitted successfully. The callback
* routine will be called when the operation is done.
* CRYPTO_MECHANISM_INVALID or CRYPTO_INVALID_MECH_PARAM
* for problems with the 'mech'.
* CRYPTO_INVALID_DATA for bogus 'data'
* CRYPTO_HOST_MEMORY for failure to allocate memory to handle this work.
* CRYPTO_INVALID_CONTEXT: Not a valid context.
* CRYPTO_BUSY: Cannot process the request now. Schedule a
* crypto_bufcall(), or try later.
* CRYPTO_NOT_SUPPORTED and CRYPTO_MECH_NOT_SUPPORTED:
* No provider is capable of a function or a mechanism.

* crypto_digest_prov()
*
* Arguments:

* sid: provider session id.
* mech: crypto_mechanism_t pointer.

* crypto_mech2id();
