Reagle Jr. (W3C)" <reagle@w3.org> cc: w3c-xml-sig-ws@w3.org (bcc: Donald Eastlake/Hawthorne/IBM) Subject: Re: Single Key in Originator Information Joseph, [...] This restriction on syntax is one of the reasons I'm pushing on differentiating the characteristics of a keyed hash versus public key mechanisms. Keyed hash mechanisms require a Recipient Info field. Public key techniques do not need to provide recipient unique information. ### Maybe I misunderstand but if the public key technique being used is Diffie-Hellman and a recipient has many DH keys, is not "recipient unique information", in particular an indication of which key to use, needed?
