Function Documentation

zpc_aes_ecb_alloc()

int zpc_aes_ecb_alloc

(

struct zpc_aes_ecb **

ctx

)

Allocate a new context for an AES-ECB operation.

Parameters

[in,out]

ctx

AES-ECB context

Returns

0 on success. Otherwise, a non-zero error code is returned.

zpc_aes_ecb_set_key()

int zpc_aes_ecb_set_key	(	struct zpc_aes_ecb *	ctx,
		struct zpc_aes_key *	key )

Set the key to be used in the context of an AES-ECB operation.

Parameters

[in,out]	ctx	AES-ECB context
[in]	key	AES key

Returns

0 on success. Otherwise, a non-zero error code is returned.

zpc_aes_ecb_encrypt()

int zpc_aes_ecb_encrypt	(	struct zpc_aes_ecb *	ctx,
		unsigned char *	ct,
		const unsigned char *	pt,
		size_t	ptlen )

Do an AES-ECB encryption operation.

Parameters

[in,out]	ctx	AES-ECB context
[out]	ct	ciphertext
[in]	pt	plaintext
[in]	ptlen	plaintext length [bytes]

Returns

0 on success. Otherwise, a non-zero error code is returned.

zpc_aes_ecb_decrypt()

int zpc_aes_ecb_decrypt	(	struct zpc_aes_ecb *	ctx,
		unsigned char *	pt,
		const unsigned char *	ct,
		size_t	ctlen )

Do an AES-ECB decryption operation.

Parameters

[in,out]	ctx	AES-ECB context
[out]	pt	plaintext
[in]	ct	ciphertext
[in]	ctlen	ciphertext length [bytes]

Returns

0 on success. Otherwise, a non-zero error code is returned.

zpc_aes_ecb_free()

void zpc_aes_ecb_free

(

struct zpc_aes_ecb **

ctx

)

Free an AES-ECB context.

Parameters

[in,out]

ctx

AES-ECB context
