.NET and Java Open Clients can access the AppServer over secure intranet connections using OpenEdge SSL. SSL provides the security by tunneling AppServer protocol requests, where data privacy is provided by symmetric key encryption and authentication between the client and server (in this case the SSL-enabled AppServer) is provided by public key (digital) certificates. The requirement for using SSL-enabled AppServer connections is that the client must have access to a root digital certificate that corresponds to a digital certificate stored on the server. For more information on managing root digital certificates for Open Clients, see see Configuration.

A secure intranet connection to an SSL-enabled AppServer from an Open Client secures the entire connection between the client and the AppServer.
