You can choose whether or not the instruction XML is digitally signed, and if so, whether or not you should be prompted to sign it when saving an instruction definition.

The Digital Signing menu allows you to select a signing certificate that has previously been imported into your certificate store.
In order to use any of the signing options you must have an appropriate certificate. If you do not, the following warning dialog appears
