Stunnel: Universal SSL Wrapper

Stunnel is a "Secure Tunnel" that allows normal, unencrypted programs to have a secure link over the network using SSL (Netscape's Secure Sockets Layer, currently the most widely used method for performing secure transactions on the web) . It is simpler than IPsec (Internet protocol security) and less complex than SSH Secure Shell, a network protocol that allows data to be exchanged over a secure channel between two computers), since it does not use public key-based authentication.

The Stunnel source code is available under the GNU General Public License, meaning it is free to use in both commercial and non-commercial applications as you see fit, as long as you provide source code (and any modifications) with the software. Your compiled Stunnel binary is 'restricted' by whatever license your chosen SSL library is under. However both OpenSSL and SSLeay are open source and similarly liberal in their licensing.
