int CRYPT_AES_DIRECT_Encrypt(
CRYPT_AES_CTX* aes,
unsigned char* out,
const unsigned char* in
);
This function encrypts one block of data, equal to the AES block size.
Key and Initialization Vector (IV) must be set earlier with a call to CRYPT_AES_KeySet and CRYPT_AES_IvSet.
| Parameters | Description |
|---|---|
| aes | Pointer to context which saves state between calls. |
| out | Pointer to buffer to store the results of the encryption. |
| in | Pointer to buffer where the data to encrypt is located. |
BAD_FUNC_ARG - An invalid pointer was passed to the function.
0 - An invalid pointer was not passed to the function.
Input and output buffers must be equal in size (CRYPT_AES_BLOCK_SIZE).

ret = CRYPT_AES_KeySet(&mcAes, key, 16, iv, CRYPT_AES_ENCRYPTION);
ret = CRYPT_AES_DIRECT_Encrypt(&mcAes, out1, ourData);
