Hi,
Went quickly through the cipher proposal, to get a somehow working implementation.
Seems to work with aes, but not with arc4.
ARC4 is a bit weird. The same function is used for encryption and
decryption, so the stream is not reset. You will likely need to set the
key prior to each encrypt/decrypt operation.
And now I wonder if we should not provide an initialization vector
for some ciphers? (like arc4).
I'm still not fully sure we need the IV. EAPoL Key-IV is only used in
certain situations. Lets try to find an AP / trace that actually sets
the IV field.
