.NET/Java Open Clients and SOAP Web service clients can access the AppServer over secure Internet connections using HTTPS. The Secure Sockets Layer (SSL) provides the security by tunneling HTTP requests, with data privacy provided by symmetric key encryption and authentication between the client and server (in this case the Web server) provided using public key (digital) certificates. The requirement for using HTTPS connections is to have access to a root digital certificate that corresponds to a certificate that is stored on the server. For more information on managing root digital certificates for Open Clients, see Configuration.

Secure Internet connections do not by themselves secure the entire route to the AppServer. OpenEdge can secure the connection beyond the Web server by supporting SSL connections from the AIA and WSA to an SSL-enabled AppServer over the intranet. For more information on AIA and WSA connections to an SSL-enabled AppServer, see OpenEdge Application Server: Developing AppServer Applications.
