Ucrypto Digest						libucrypto(3LIB)

NAME
	crypto_digest, crypto_digest_init, crypto_digest_update,
	crypto_digest_final - cryptographic hashing operations

SYNOPSIS
	#include <libucrypto.h>
	int crypto_digest(crypto_mechanism_t *mech, crypto_data_t *data,
	    crypto_data_t *digest, crypto_call_req_t *cr);

int crypto_digest_init(crypto_mechanism_t *mech, crypto_context_t *ctxp,
	    crypto_call_req_t *cr);

int crypto_digest_update(crypto_context_t ctx, crypto_data_t *data,
	    crypto_call_req_t *cr);

int crypto_digest_final(crypto_context_t ctx, crypto_data_t *digest,
	    crypto_call_req_t *cr);

DESCRIPTION
	The function crypto_digest() performs a digest operation on single
	part data.

The function crypto_digest_init() begins a digest operation on multi-
	part data.

The function crypto_digest_update() continues a digest operation on
	multi-part data.

The function crypto_digest_final() finishes a digest operation on
	multi-part data.

The ucrypto digest API currently supports the following mechanisms:
	CRYPTO_MD5, CRYPTO_SHA1, CRYPTO_SHA224, CRYPTO_SHA256,
	CRYPTO_SHA384, CRYPTO_SHA512,  CRYPTO_SHA512_160,
	CRYPTO_SHA512_224, CRYPTO_SHA512_256, CRYPTO_SHA512_T
	To use a given mechanism for an API call, set the cm_type field of
	the crypto_mechanism_t argument to the appropriate value.

RETURN VALUES
       Upon successful completion, crypto_digest(), crypto_digest_init(),
       crypto_digest_update(), crypto_digest_final() will return
       CRYPTO_SUCCESS (0x00). Otherwise, they return an error code. See
       ucrypto_strerror(3LIB) for descriptions of error codes.
