🔏 Netfox 0.19.0 — what a certificate says about itself

🔏 Netfox 0.19.0 is out: the certificate card

Every home network has a few TLS services nobody looks at until a browser refuses one: the NAS, the printer, the router's own page. Netfox now reads what they present and says what's wrong with it.

📜 Issued to, issued by, expires — read from the certificate the server presents, on any port that speaks TLS from the first byte.

⛔ Expired: named, with the date.

🪪 Signed by itself: nothing vouches for it. Normal on a home device that made its own, worth a second look anywhere else — and the card says exactly that.

⏳ Two warnings before they bite: runs out within three weeks, or not valid yet (which is usually the device's clock, not the certificate).

🔒 On demand only, behind the same privacy switch as the service lookup. Netfox never starts a conversation unasked, and the card stays hidden in Demo Mode.

The service lookup on an open port; the certificate card sits beside it
