ocrypto_aes_gcm_update_aad()

void ocrypto_aes_gcm_update_aad	(	ocrypto_aes_gcm_ctx *	ctx,
		const uint8_t *	aa,
		size_t	aa_len
	)

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

AES-GCM incremental aad input.

The generator state ctx is updated to include a data chunk aa.

This function can be called repeatedly until the whole data is processed.

Parameters

ctx	Generator state.
aa	Additional authenticated data.
aa_len	Length of aa.

Remarks

Initialization of the context ctx through ocrypto_aes_gcm_init is required before this function can be called.

ocrypto_aes_gcm_update_aad must be called before any call to ocrypto_aes_gcm_update_enc or ocrypto_aes_gcm_update_dec.
