ocrypto_aes_cbc_update_dec()

void ocrypto_aes_cbc_update_dec	(	ocrypto_aes_cbc_ctx *	ctx,
		uint8_t *	pt,
		const uint8_t *	ct,
		size_t	ct_len
	)

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

AES-CBC incremental decryption.

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

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

Parameters

	ctx	Context.
[out]	pt	Plaintext.
	ct	Ciphertext.
	ct_len	Length of ct and pt. Must be a multiple of the block size.

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.
