Function Documentation

sha2xx_final()

void sha2xx_final	(	sha2xx_context_t *	ctx,
		void *	digest,
		size_t	dig_len
	)

SHA-2XX finalization.

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

Parameters

ctx	sha2xx_context_t handle to use
digest	resulting digest, this is the hash of all the bytes
dig_len	Length of digest

sha2xx_pad()

void sha2xx_pad

(

sha2xx_context_t *

ctx

)

SHA-2XX initialization.

Begins a SHA-2XX operation.

Parameters

ctx	sha2xx_context_t handle to init

sha2xx_update()

void sha2xx_update	(	sha2xx_context_t *	ctx,
		const void *	data,
		size_t	len
	)

Add bytes into the hash.

Parameters

	ctx	sha2xx_context_t handle to use
[in]	data	Input data
[in]	len	Length of data
