  • Hi, on Symbian the only possibility is C++ for such application. BR STeN – STeN Oct 25 '10 at 05:54

It has already been done: http://en.wikipedia.org/wiki/Skype_security

To implement it, you would need a fast language (a delay of no more than maybe 10 milliseconds, because you still have network latency to deal with) so something like C or C++, maybe Java when used with JIT. Check out Java SE Security Package for simple SSL connections.

Of course, the easy way to do this would just be an ssh or VPN tunnel.

  • Thank You sir but i wanted to implement this application for mobiles and is in search of some API to access voice calls so that they can be encrypted and could be sent through VOIP. can you please suggest some API for j2me or symbian c++ which would help me in my job. – Pratik Agrawal Oct 24 '10 at 12:58
  • Does skype run on Symbian OS? I don't think so. – President James K. Polk Oct 24 '10 at 20:41
