Hi,
I've looked in RFC 3748, and chapter 5.4 shows up with the following:
5.4. MD5-Challenge
Description
The MD5-Challenge Type is analogous to the PPP CHAP protocol
[RFC1994] (with MD5 as the specified algorithm). The Request
contains a "challenge" message to the peer. A Response MUST be
sent in reply to the Request. The Response MAY be either of Type
4 (MD5-Challenge), Nak (Type 3), or Expanded Nak (Type 254).
This would mean that EAP uses the same MD5 challenge algoritm as with the
CHAP protocol, please correct me if I'm wrong!

regards,
Henk
