Function Documentation

sha512_common_final()

void sha512_common_final	(	sha512_common_context_t *	ctx,
		void *	digest,
		size_t	dig_len
	)

SHA-512 finalization.

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

Parameters

	ctx	sha512_common_context_t handle to use, must not be NULL
[out]	digest	resulting digest, this is the hash of all the bytes
[in]	dig_len	Length of digest

sha512_common_pad()

void sha512_common_pad

(

sha512_common_context_t *

ctx

)

SHA-512 initialization.

Begins a SHA-512 operation.

Parameters

ctx	sha512_common_context_t handle to init, must not be NULL

sha512_common_update()

void sha512_common_update	(	sha512_common_context_t *	ctx,
		const void *	data,
		size_t	len
	)

Add bytes into the hash.

Parameters

	ctx	sha512_common_context_t handle to use, must not be NULL
[in]	data	Input data
[in]	len	Length of data
