C# and C++ socket data encryption

Question

Im writing a C# client and C++ server which should communicate via TCP sockets with no encryption. Everything is great. However I need to encrypt some of the data (but not all of it) like login information. I am looking for a asymmetric algorhythm to implement on the C# and C++ side to implement secured exchange of login data. Could you help me?
