int CRYPT_AES_IvSet(
CRYPT_AES_CTX* aes,
const unsigned char* iv
);
This function sets the IV that AES will use for later processing.
The key must be set previously with CRYPT_AES_KeySet.
| Parameters | Description |
|---|---|
| aes | Pointer to context which saves state between calls. |
| iv | Pointer to buffer holding the initialization vector. |
BAD_FUNC_ARG - An invalid pointer was passed to the function.
0 - An invalid pointer was not passed to the function.
Direction, as set previously in CRYPT_AES_KeySet, is preserved.
CRYPT_AES_CTX mcAes;
int ret;
strncpy((char*)iv, "1234567890abcdef", 16);
ret = CRYPT_AES_IvSet(&mcAes, iv);
