      @bascule @seancribbs @halorgium @_emboss_ So, you do want to use X509? I'm so confused!

      @evanphx @seancribbs @halorgium @_emboss_ yes! Client presents X.509 cert, server verifies certificate chain, app can then trust the subject

      @bascule @seancribbs @halorgium @_emboss_ OH. I think I read your tweet wrong. You want a standalone X509 lib, yes?

      @bascule @evanphx @seancribbs @halorgium Just reading the certificate and its field is certainly possible.

      @_emboss_ @evanphx @seancribbs @halorgium how should the subject (or possibly the entire certificate) be represented to end-users?

      @bascule I'd pass the whole certificate as binary. String representation of subject e.g. is shaky, subject to library interpretation.

      @bascule The email field for example is parsed/interpreted differently by different libraries... The whole blob is the safest thing to do.

      @_emboss_ by whole blob you mean DER then?

          @_emboss_ well, you could also expose PEM, right? ;) Too many ways to do things with X.509

          @bascule Oh right, I'd even prefer PEM if you send it over the wire!

          @_emboss_ well, we're talking about the certificate presented by the client in a TLS handshake here...

          @bascule OK, I guess then either would be fine - you could simply forward what was extracted from the handshake?

          @bascule I'd naively say both should be fine, would need to know more about how it's being used to be more precise. IRC, #ruby-core?

          @_emboss_ an abstract API that Ruby web servers can use to pass through the client cert used in an HTTPS request
