AH + ESP Interoperability
hello,
I am new to this mailing list and have a couple of questions.
First, is there a searchable archive for this list?
The second question is wrt Interoperability and authentication.
What is the accepted method of authentication calculation pertaining to
crypto libraries? I have seen different implementations with different
methods.
One implementation does it as.
Update(ipheader)
Update(AH hdr + data)
Final
Another implementation does it as
Update(ipheader)
Update(AH hdr)
Update(padding)
Update(data)
Final
The RFC specifies
Update(pdu)
Final
I apologize if this has been discussed before and would appreciate
pointers to relevant information
Thanks
Murtaza
