My stuff is aimed at teaching, not efficiency. The others are probably much better implementations. The last one has both C++ and Java versions where my stuff is all C. So lots of choices!

OpenVPN is a robust and highly flexible tunneling application that uses all of the encryption, authentication, and certification features of the OpenSSL library to securely tunnel IP networks over a single TCP/UDP port.
