SoftwareAuthKeyLoader

Software P25 Link Layer Authentication Key Loader (Windows .NET Console Application)

Supports all Manual Rekeying Features for Authentication per TIA-102.AACD-A

Download: latest release

Disclaimer

This utility is not intended for use in a production setting – security was not a consideration of the design. If you are operating a production system, use a commercial keyloader that supports P25 link layer authentication.

The subscriber identity and the link layer authentication key loaded into to the radio need to be entered into the trunking system in order for the authentication process to be successful. This tool by itself will not allow access to a link layer authentication protected trunking system.
