ocrypto_aes_gcm_init()

void ocrypto_aes_gcm_init	(	ocrypto_aes_gcm_ctx *	ctx,
		const uint8_t *	key,
		size_t	size,
		const uint8_t	iv[12]
	)

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

AES-GCM initialization.

The context ctx is initialized using the given key key and initial vector iv.

Parameters

[out]	ctx	Context.
	key	AES key. May be NULL.
	size	Key size (16, 24, or 32 bytes).
	iv	Initial vector. May be NULL.

Remarks

If key is NULL only iv is set. If iv is NULL only key is set. Both key and iv must be set before update is called.
