Is it possible to use an electronic signature in Navigator?

In the NAVIGATOR system there is a possibility to sign pdf or other Microsoft Office documents with a digital signature. For proper work you need to download a local app for signatures and configure the system. The local app was made by the Archman team. More about technicalities can be found under the link. NAVIGATOR can be integrated with any external system, which accepts documents signed digitally, with the only condition that it has an interface for data exchange.
