Discussion
After approving the minutes of the January 2 meeting, TAG reviewed a few of its outstanding action items:
[2–January – Eric will look into possible SSH.com support for cert–based authentication.]
Still to do. Support for cert–based authentication exists only in the commercial version of the server; the group agreed to draft a letter to SSH.com, to be signed by as many representatives of higher education as possible, asking that support be added to the free version of both server and client. Jim noted that VanDyke now supports this in SecureCRT on the client side and SSH on the server side. Bob Morgan noted that there's not even a draft IETF standard for SSH authentication with X.509. [AI] Jim will find out what cert store the VanDyke and SSH.com clients use. [2–January – Eric will help Annie and Carrie at Wisconsin go through the HEPKI demo and get certs installed in their browsers.] Still to do. [19–December – Eric will ask Scott Fullerton to test opaque signatures on the TAG list.] Done. Testing has shown that Outlook and Outlook Express can't read opaque–signed messages, but Netscape and Eudora/Tumbleweed can. Eric summarized the testing so far by saying "the opaque signing thing isn't going to work very well."
Much of the call was devoted to review of Jim's draft description of the PKI Lite S/MIME project (http://middleware.internet2.edu/hepki–tag/pki–lite/pkilite–smime.html). Jim has incorporated the group's comments into an updated version of the document at http://middleware.internet2.edu/hepki–tag/pki–lite/pkilite–smime_2.html. Some action items also came out of this discussion: [AI] Jim and Judith will add links to free cert–issuing web sites from the HEPKI and CREN sites respectively. [AI] Jim will find out how much the Tumbleweed plugin costs. [AI] Bob Morgan and Eric will try to find out if anyone is planning to add S/MIME to pine. There was a short discussion of the "why not PGP?" issue; Bob Morgan pointed out that "there is precisely no technical distinction between PGP and S/MIME" –– the CA model associated with S/MIME is separable from it. Bob also observed that while PGP works fine for its current community, it's not going to grow much further; S/MIME has growth potential.
The group revisited its decision to recommend in the PKI Lite cert profile that no fields be marked critical; the RFCs say that basic constraints and key usage should be marked critical. Jim noted that TAG's intent was to avoid problems with software that doesn't deal well with critical fields; now that TAG has limited the software it will be dealing with, maybe it should follow the RFC recommendation. [AI] On the next call that David Wasley attends, TAG will reopen the question of which PKI Lite cert fields should be marked critical.
Finally, Bill Doster discussed
a part of the KX.509 project
that uses a PKCS11 plugin
to enable Netscape to access
the user's cert store in
the same way Internet Explorer
does. See http://www.citi.umich.edu/projects/kerb_pki/.
