Nice find. Most people really shouldn’t be using AFP. I know that Classic
MacOS machines store the passwords on disk using a simple XOR cipher.

Any local storage of passwords is only as secure as the security of the key store. The lack of sophistication in the password store in many AFP clients is well documented; in fact, the AFP server can advise the client to not allow storing the password.

I would assume that they also transmit the password using the same cipher.

<http://developer.apple.com/documentation/Networking/Conceptual/AFP/>

An AFP client /may/ transmit authentication information in the clear, but for at least ten years, the standard method used was a DES-encrypted challenge-response protocol. I believe a challenge-response protocol was the preferred authentication protocol from the very start of AFP.

SecureMac.com has a article on this if anyone is interested.

Is that so?  Google didn't seem to find much...
