Virtual Dongle image created by programs, such as EdgePro and Sentinel Dongle Dumper, then used by dongle emulators; contains a virtual copy of a dongle, which includes license information and acts as a key that allows software to be run.
A dongle is a physical device used to activate expensive software. The device helps protect the software from being stolen by hackers. DNG files are designed for users to backup or recover keys stored in the physical dongles that are lost or broken.
