SharkSslPSAHash_compute()

int SharkSslPSAHash_compute	(	U8 *	digest,
		U16	digestSize,
		U16 *	digestLen,
		const U8 *	data,
		U32	dataLen,
		psa_algorithm_t	algorithm
	)

One-shot SHA3-224/256/384/512 or fixed SHAKE256-512 through PSA.

After output arguments pass validation, any later failure clears digestSize bytes.

Generic variable-length XOF is deliberately excluded. Returns zero on success; clears digest and returns -1 on failure.

SHAKE256_512 produces a fixed 64-byte result here.

Parameters

digest	U8 *; required output buffer.
digestSize	U16; output capacity in bytes, at least the selected digest size.
digestLen	U16 *; required result byte count; set to zero before validation.
data	const U8 *; input bytes, or NULL with dataLen=0.
dataLen	U32; input byte count.
algorithm	psa_algorithm_t; PSA_ALG_SHA3_224, PSA_ALG_SHA3_256, PSA_ALG_SHA3_384, PSA_ALG_SHA3_512, or PSA_ALG_SHAKE256_512.

Returns

int: 0 on success; -1 for invalid arguments, unsupported algorithms/policies, or provider failure.
