Actually I have 18 bytes of data so 16 bytes I am decryting with CBC

For this 2 bytes I am using IV as 16 bytes of decrypted data(means
plaintext),but this 2 bytes data is not maching.

I don't think it's documented. I pass in 0 and it works.
My notes also say that ivec is altered, so make a copy if you have to
preserve the original value.

Hi All,
If I use the below function
void AES_ofb128_encrypt(const unsigned char *in,
0 for encryption or decryption?

Am I missing something, or is this a trick question?
For OFB, aren't they the same

XOR ?
