int CRYPT_AES_KeySet(
CRYPT_AES_CTX* aes,
const unsigned char* key,
unsigned int keyLen,
const unsigned char* iv,
int dir
);
This function sets the key, IV, and direction (encryption or decryption) that AES will later perform.
None.
Parameters | Description |
---|---|
aes | Pointer to context which saves state between calls. |
key | Pointer to buffer holding the key itself. |
keyLen | Length of key in bytes. |
iv | Pointer to buffer holding the initialization vector. |
dir | Which operation (CRYPT_AES_ENCRYPTION or CRYPT_AES_DECRYPTION). |
-
BAD_FUNC_ARG - An invalid pointer was passed to the function.
-
0 - An invalid pointer was not passed to the function.
None.
