Function Documentation

sha384()

void sha384	(	const void *	data,
		size_t	len,
		void *	digest )

A wrapper function to simplify the generation of a hash.

This is useful for generating sha384 for one single buffer in a single step.

Parameters

[in]	data	pointer to the buffer to generate hash from
[in]	len	length of the buffer
[out]	digest	optional pointer to an array for the result, length must be at least SHA384_DIGEST_LENGTH

sha384_final()

static void sha384_final ( sha384_context_t * ctx, void * digest )

inlinestatic

SHA-384 finalization.

Pads the input data, exports the hash value, and clears the context state.

Parameters

	ctx	sha384_context_t handle to use, must not be NULL
[out]	digest	pointer to resulting digest, this is the hash of all the bytes. Length must be at least SHA384_DIGEST_LENGTH

Definition at line 74 of file sha384.h.

sha384_init()

void sha384_init

(

sha384_context_t *

ctx

)

SHA-384 initialization.

Begins a SHA-384 operation.

Parameters

ctx	sha384_context_t handle to init, must not be NULL

sha384_update()

static void sha384_update ( sha384_context_t * ctx, const void * data, size_t len )

inlinestatic

Add bytes into the hash.

Parameters

	ctx	sha384_context_t handle to use, must not be NULL
[in]	data	Input data
[in]	len	Length of data
