QRV — verify your callsign

Prove you hold your callsign using the Logbook of the World certificate the ARRL already issued you.

Your key never leaves this computer. This page runs entirely in your browser — it makes no network requests, and your certificate file is never uploaded anywhere. It reads the file locally, signs the one challenge string from your phone, and forgets everything when you close the tab. You can disconnect from the internet before using it; it will still work.

1 · Challenge from QRV

Open QRV → Profile → Verify callsign, and copy the challenge shown there.

2 · Your LoTW certificate

In TQSL: File → Export Callsign Certificate, and save a .p12 file. The password you set when exporting it

QRV checks the signature and the ARRL's signature on your certificate, so it learns your callsign is really yours without ever seeing your key. About the Q-code apps
