Stuel 5.42

Stuel is a program that allows you to encrypt arbitrary TCP coections inside SSL (Secure Sockets Layer) available on both Unix and Windows. Stuel can allow you to secure non-SSL aware daemons and protocols (like POP, IMAP, LDAP, etc) by having Stuel provide the encryption, requiring no changes to the daemon's code.

The Stuel source code is not a complete product -- you still require a functioning SSL library such as OpenSSL or SSLeay in order to compile stuel. This means that stuel can support whatever (and only) that which your SSL library can, without making any changes in the Stuel code.

The Stuel 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 Stuel 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.
