Is Xbrl signing safe?

Clean risk

Xbrl signing forwards certificate and signing requests from scoped pages to a local native signing app.

On localhost, XBRL-related domains, and file pages, the extension exposes page functions for certificate, signing, and version requests. Those requests are passed through the extension to the installed native messaging host named xbrl.signing, so the local signing app receives the signing-related data from those pages.

Shared hosts - 1 hostname

Hostnames hardcoded in this extension that few other listings call. That can mean one operator behind both, and it can equally mean a small shared vendor, so it is context rather than a conclusion. Hosts that many listings call are left out: they are services, not connections.

Where it sends data
