I have a smartcard that can be read by websites using a Java applet (see http://www.springcard.com/online/applet_pcsc/). I would like to monitor and is to replay packets going from this java applet to the network. The problem is that it uses SSL. I tried to make IcedTea plugin (the open source version of oracle's java plugin, since oracle's one do not work properly with the card on my system) use a proxy (to catch the traffic on Burp Suite) and tried a passive sniffing with Wireshark, but it cannot decrypt SSL.

How can I capture and decrypt the SSL traffic? And if I can't is there a way to get the data before it gets encrypted by java (since everything runs on my machine, I can perform pretty much any manipulations)?

    You can use Burp proxy, which can intercept SSL. It will generate a CA certificate, which you need to install in your Java root certificate store. – paj28 Sep 9 '14 at 9:38
  • I already did that, and the Java applet seemed to fail starting. Same thing again but after 5-6 attempts it now works properly. Thank you! – Thüzhen Sep 9 '14 at 10:03

paj28's solution works. I had to go to IcedTea's configuration and add the Burp certificate to the list of certificates and then configure IcedTEa to use Burp as a proxy. I don't now why but IcedTea seemed to mess up (refusing to launch the applet) at first, but after a few attempts it works!
