I''m writing an application that will require users to preset a client certificate as their authentication token. The logistics of issuing, installing, and securing the certificates are taken care of, so I''m not looking for a discussion on that. :) I''ve read: http://article.gmane.org/gmane.comp.lang.ruby.rails/1993 which gets me half way there by setting up an SSL-enabled server that requires a valid client certificate. What I need to know now is how to access the certificate presented so that I may extract data from it. I haven''t had much luck w/ the API docs, and I admit that I''m a bit of a noob when it comes to Rails, so any help the list can offer me is greatly appreciated. Thanks!
