SSL overview

The Secure Sockets Layer (SSL) protocol creates a standard SSL connection between the client and the server. The client contacts the server and checks to make sure that the server has a valid certificate. This type of connection ensures that all data exchanged between client and server is encrypted, and is therefore not readable by a third party on the Internet.
Extension for Terminal-based Applications supports SSL connections to host sessions using Host On-Demand SSL functions. The SSL connection to a 3270 session is set up by using an open source SSL package called Stunnel.

Stunnel is a program that enables encrypting arbitrary TCP connections inside SSL and is available on both UNIX and Windows operating systems. With Stunnel you can secure non-SSL aware daemons and protocols by providing the encryption that requires no changes to the daemon code.
