How can I generate a QR code from a OpenPGP/GnuPG private key on Windows 7?

Context: I created a private key pair on a Windows computer and want to import the key to my phone. The phone app has options: "Import from File", "Scan QR Code".

I think a secure way would be to create a QR code on the computer and use the phone app to scan it.

What I tried already: There is Windows program called "qrencode-win32" (https://code.google.com/archive/p/qrencode-win32). But it didn't work:


  • If the result is too large, you need to select a larger QR code.
