Am I correct on this, Hugo?

Again, > this depends on what my co-authors say and on general consensus. I am not sure if draft draft-ietf-ipsec-ah-md5 is needed anymore. The mandatory function for implementation can be specified in Atkinson's draft-ietf-ipsec-auth by referencing a protocol-independent description of the function as done in draft-krawczyk-keyed-md5 or similar document. > > It would also be nice if Hugo were to post a message explaining the I hope the message I sent an hour ago will help in this regard. > rationale for this in approximate laymans terms.

Contributing to draft-ietf-ipsec-ah-md5 would mean for me changing it to the language used in my draft. Hugo > > Perry
