ocrypto_aes_ctr_update()

void ocrypto_aes_ctr_update	(	ocrypto_aes_ctr_ctx *	ctx,
		uint8_t *	ct,
		const uint8_t *	pt,
		size_t	pt_len )

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

AES-CTR incremental encryption/decryption.

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_ctr_init is required before this function can be called.
