It seems to me that the goals and mechanisms of the in-lining spec are very similar to those of the "Magic Envelope" which is defined in the Salmon<http://www.salmon-protocol.org/>Magic Signatures specification. http://salmon-protocol.googlecode.com/svn/trunk/draft-panzer-magicsig-00.html
I suggest that we try to see if Magic Envelopes can be used in this context. Using them would increase consistency across implementations while also providing a way to independently sign in-lined content. bob wyman On Sun, Aug 22, 2010 at 9:10 PM, James Snell <[email protected]> wrote: > Ok... finally was able to get back to this...
