What This Means for Transparency
Algorithm Not Confirmed
No source we have checked names the encryption algorithm for these 2,803 agencies. That is a gap in what is published, not a verified encryption method. Check RadioReference or an active Broadcastify/OpenMHz feed directly for an agency's current status before drawing conclusions from this page.
Take Action
If your local agency uses encryption (algorithm not published), you can advocate for transparency. Contact elected officials and attend public meetings.
Learn How to Fight BackFrequently Asked Questions
What does an unpublished encryption algorithm mean here?
The agency is recorded as encrypting some or all of its radio traffic, but no source we have checked names the encryption algorithm.
Can an unpublished encryption algorithm be decrypted with a consumer scanner?
We don't know. No source we have checked names the cipher for these 2,803 agencies, so this page makes no claim about how strong it is. Check RadioReference or an active Broadcastify/OpenMHz feed for an agency's current status.
Why is the algorithm not published for so many agencies?
RadioReference, the source behind most of this database, marks a talkgroup as encrypted without naming the cipher. Our records once listed an algorithm for most agencies, imported from community listings; no source we fetched confirmed those, so we stopped displaying them. 2,684 non-refuted agencies are in this group.
