Is there a web application that checks the TLS capabilities of the browser? At least

  • supported protocols and versions
  • certificates

It should create a detailed report of the results. There're good tools for checking server configurations but same tools can not be used to check browser implementation.

There would be two ways:

  • an app to deploy on an own server
  • a server that provides this as a service

Where the first option is preferred over the second.

  • What are you going to use the reports for? We prefer questions that contain objective requirements (check, but they're rather seen) as well as a goal to accomplish. – Gilles 'SO- stop being evil' Feb 20 '14 at 1:03

    I use mike's toolbox mikestoolbox.net and mikestoolbox.org (I think there is some difference between those variants, but forgot the details) – CodesInChaos Feb 20 '14 at 10:19
  • What do you mean by "certificates" in the context of client capabilities? Are you talking about the rarely used feature of client certificates, or something else? – CodesInChaos Feb 20 '14 at 10:23
  • Maybe the requirement about certificates can be left out. I think it's more important, that the solution can be self-hosted.. – Jens Piegsa Feb 20 '14 at 14:30
  • @JensPiegsa If being able to host the solution on your own server is a primary requirement, then the question should have stated that at the outset - instead of leaving open the option of "a server that provides this as a service". To eliminate that option would fundamentally change the question. – Iszi Feb 20 '14 at 15:02

Go back to the Projects page on the site for the SSL Server Test you linked, and you'll find that Qualys SSL Labs also has an SSL Client Test which provides a rather detailed report.

    Could you expand on this answer to demonstrate how this tool is a good fit? For example, a sample report would help. See our answer quality guidelines. – Gilles 'SO- stop being evil' Feb 20 '14 at 1:02
  • Thanks for the helpful response. I think the (maybe temporary) downvote comes from a software rec "quality guard" intended to encourage an update. – Jens Piegsa Feb 20 '14 at 23:14
