ocrypto_hmac_sha512_final()

void ocrypto_hmac_sha512_final	(	ocrypto_hmac_sha512_ctx *	ctx,
		uint8_t	r[(64)] )

#include <crypto/nrf_oberon/include/ocrypto_hmac_sha512.h>

HMAC-SHA512 output.

The generator state ctx is updated to finalize the HMAC for the previously processed message chunks. The authenticator is put into r.

Parameters

	ctx	Generator state.
[out]	r	Generated HMAC value.

Remarks

Initialization of the generator state ctx through ocrypto_hmac_sha512_init is required before this function can be called.

After return, the generator state ctx must no longer be used with ocrypto_hmac_sha512_update and ocrypto_hmac_sha512_final unless it is reinitialized using ocrypto_hmac_sha512_init.
