aes_cbc_decrypt()

int aes_cbc_decrypt	(	aes_ctx	ctx,
		const unsigned char *	ciphertext,
		size_t	ciphertext_len,
		unsigned char *	plaintext,
		const unsigned char	iv[AES_BLOCK_SIZE]
	)

Decrypt data using AES-128 in CBC mode.

Parameters

ctx	AES context from aes_create_ctx()
ciphertext	Input data
ciphertext_len	Length in bytes (must be multiple of AES_BLOCK_SIZE)
plaintext	Output buffer (same length as ciphertext)
iv	16-byte initialization vector

Returns

AES_OK on success, AES_ERR_* on error
