Negotiated security
TLS version and cipher suite describe a completed secure connection when the hosting path exposes them.

The comparison signature is generated from application-visible request details. It is not a JA3 or JA4 TLS handshake fingerprint.
What this signature describes
TLS protects an HTTPS connection. The negotiated TLS version and cipher suite describe that connection when the hosting path makes them available to the application.
This tool combines available TLS details, the HTTP protocol and selected request headers into a comparison signature. Open the detected details to copy it, then compare after a browser or proxy change. For properties exposed by page scripts instead, use the browser fingerprint test.
The hosting path matters
A CDN or reverse proxy can terminate TLS before the request reaches Localtonet. Missing application values do not mean your browser connection is insecure.
Comparing signatures
Use the app- signature to compare request shapes after a browser or configuration change. It cannot identify a person.
JA3 and JA4
Those fingerprint families require details from the TLS ClientHello. This application signature uses a different source of evidence.

Common questions
Is this a JA3 or JA4 fingerprint?
No. It is an application-layer HTTP/TLS request signature and does not inspect a raw ClientHello.
Why is the TLS version unavailable?
The TLS connection may terminate at a reverse proxy or CDN that does not forward the negotiated details to the application.
Why does the signature change?
HTTP negotiation, headers, browser updates and intermediary behavior can all change the application-visible request.
