The Cisco ASA Keymaker by SSG tool works by taking the device's serial number and other identifying information as input. The tool then uses a complex algorithm to generate a valid license key that can be used to activate the device. The generated key is unique to the device and ensures that the device can be configured and activated with the required features and functionality. Cisco ASA Licensing
