ocrypto_aes_cbc_pkcs_init()

void ocrypto_aes_cbc_pkcs_init	(	ocrypto_aes_cbc_pkcs_ctx *	ctx,
		const uint8_t *	key,
		size_t	size,
		const uint8_t	iv[16],
		int	decrypt )

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

AES-CBC 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.
	decrypt	If 0, initialize for encryption; If 1, initialize for decryption.

Remarks

If key is NULL only iv is set. If iv is NULL only key is set. If not set by the same call, key must be set before iv.
