I have a certificate file (with extension .cer) that has content which looks something like this.
-----BEGIN CERTIFICATE-----
lots of data here
-----END CERTIFICATE-----
It is our signing certificate. I am sharing it with a third party so that they can import it in the gpg public keyring. They are using below command to import it
gpg --import signing_cert.cer
But it gives this error.
gpg: please see http://www.gnupg.org/faq.html for more information
gpg: no valid OpenPGP data found.
gpg: Total number processed: 0
Looks like it might certificate format used in both Windows and gpg is different. Is there a way for my signing certificate to be imported into gpg public keyring. Any help is highly appreciated.
