ABSTRACT:
A system and method is provided whereby a system or application programmer may control encryption on or off during a connection oriented session between a client and a server over the Internet/intranet. This is done by providing a keyword or command, such as a Data Description Specification (DDS) keyword or a User Defined Data Stream (UDDS), to insert into a data stream intended for the client an architecture command, the 5250 Write Single Structured Field (WSSF) architecture command carrying an unique structured field to indicate when encrypted mode should be made active or inactive.
