[OpenID] OpenID + Government

Wed Aug 12 20:42:22 UTC 2009

Complexity could be minimally increased by defining an artifact profile.

Encryption using artifact profile requires no specification, comes for
free by having OP SSL endpoints.

Artifact profile would reduce the length of URLs, currently a problem
(not all implementations seem to handle POST very well, and POST can
be annoying on mobile devices or when changing from SSL to non-SSL
context). I think it would be more beneficial on that basis than even
from a security standpoint.

Otherwise, I agree with John's assessment.
