The clipboard can be used to securely exchange text in Unicode format between TightGate-Pro and the workstation. To do this, a text is marked with the mouse, copied to the clipboard via the context menu or a key combination and then pasted from the clipboard to the workstation. This text transfer via the clipboard also works in the opposite direction.
Only text in Unicode format is transferred via the clipboard. It is not possible to exchange programmes or images via the clipboard. Formatting is also lost during transfer. The file lock must be used for file transfer. The clipboard supports the versatile UTF-8 encoding. This means that any special characters requested by the TightGate viewer can be transferred.
The general settings of the clipboard are system-wide and are made via the administrator config .

Text transfer via the clipboard is configured in the TightGate-Pro standard in such a way that each transfer does not have to be confirmed by the user. In deviation from this, the TightGate viewer can be started with the parameter -tgprocc, which forces a case-by-case confirmation of any use of the clipboard. For the CC certified version of TightGate-Pro, case-by-case confirmation is mandatory. The following sections describe how to use the single case confirmation procedure. The use of the single case confirmation requires that the clipboard is activated on the server side at TightGate-Pro.
