I'm responsible for the SSLSocket code and more recently for the
HttpURLConnection code. That code does look right to me on a quick
review. One thing you could try to see if you can get a better
diagnostic using the non-OpenSSL provider by saying
SSLContext.getInstance("TLS", "HarmonyJSSE");I'd also try to get a tcpdump of the handshake to see what might be going wrong in case the issue is just problem negotiating an cipher suite in common between both sides. I think the emulator might have tcpdump installed, I could provide some notes on how to run it. I might also log with Log.e(TAG, "message", e); so that it will print the full stack of the exception in case their is more detail, but i'm not expecting much here. I'm really hoping that the other SSLSocket impl which give more user friendly messages than OpenSSL -bri On Thu, Aug 23, 2012 at 4:21 AM, Marco Serioli <[email protected]> wrote: > I'm developing an android application on v13 target sdk and I'm trying to > secure connection from android device to my tomcat server v6 with SSL > enabling also clientAuth.
