I'm using the mmCAU library, and I'm able to run cau_aes_set_key, cau_aes_encrypt, cau_aes_decrypt with a 16bytes key. It worked and I could retrieve the original plaintext on my Kinetis K60. However, the documentation says it's CBC and I don't get how the Initilization vector is picked (This I cannot decrypt on my desktop when I receive it from the network)
Where can I set this initilization vector ?
I'm using "CAU and mmCAU version 2.3".
