ocrypto_aes_gcm_update_enc()

void ocrypto_aes_gcm_update_enc	(	ocrypto_aes_gcm_ctx *	ctx,
		uint8_t *	ct,
		const uint8_t *	pt,
		size_t	pt_len
	)

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

AES-GCM incremental encryption.

The plaintext pt is encrypted to the ciphertext ct using the context ctx.

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

Parameters

	ctx	Context.
[out]	ct	Ciphertext.
	pt	Plaintext.
	pt_len	Length of pt and ct.

Remarks

ct may be same as pt.

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