I get whonix gateway via HTTP mode (‘Download Easy’).
Next, I downloaded Patrick’s certificate (whonix signing key), and imported it to OpenPGP via Kleopatra. Next, i signed it via my certificate.
Next, i downloaded OpenPGP signature for gateway.
I select Decrypt/Verify file, select signature for gateway (.asc) as input file and gateway image as signed data.
The result is that signature is valid but with UNKNOWN certificate.
Whether there should be signed as Patrick? (i have certificate imported correctly i think).
