How can I implement encryption between server side in (php/python) and C++ (Win32/Native Windows)?

I have to transfer data between server side (using php or python) and client side (C++ using Win32 APIs). I am not s开发者_开发知识库ure that what functions/APIs or Libs I can use on the both sides so that both sides should be able to communicate. I am not looking for some complicated public/private key or using https but a simple encryption method. Any help in this regards would be of great help.

Thanks in advance!

Use OpenSSL on client side and OpenSSL on server side. In other way you writing "I am not looking for some complicated" but if you don't want use some complicated then you don't have encryption. Easiest way is use cleartext transmission without encryption, if you searching something like this use for example ROT13 (str_rot13) but this is not give you any encryption.
