Handles Pane
The Handles pane is displayed at the bottom-left of the Sentinel LDK ToolBox window for the Sentinel Licensing API and Sentinel License Generation API.
After you have logged into a Sentinel protection key or initialized a license generation session, a session handle is generated. The handle is an identifier used by these APIs to recognize a specific session. Active handles are always displayed in the Handles pane.
The session handle is a required parameter for most API calls. If you have multiple active login calls to a Sentinel protection key or multiple active sessions for license generation, select the relevant entry from the Handles pane.
