I created an RSA signing key using GnuPG.
I have few files and I want to sign these files and store online.
I signed these using GnuPG. If the original file is a.txt, GnuPG created a 1 KB file with the extension .pgp, which holds the signature.
I want to know how to verify the original a.txt using GnuPG.
I tried this:
- Right-clicked GnuPG option and selected: "Verify"
- On click of Verify, GnuPG throws error: "Not an OpenPGP or S/MIME signature".
I assumed GnuPG will ask about 1 kb .pgp file and will verify.
How to verify the original file correctly?
