    Stunnel Universal SSL Wrapper
    Stunnel is a program that allows you to encrypt arbitrary TCP connections inside SSL (Secure Sockets Layer) available on both Unix and Windows. Stunnel can be used to securely wrap unencrpyted FIX traffic. The Stunnel source code is not a complete product — you still require a functioning SSL library such as OpenSSL or SSLeay in order to compile stunnel. This means that stunnel can support whatever (and only) that which your SSL library can, without making any changes in the Stunnel code. The Stunnel source code is available under the GNU General Public License.
