Is signing a file with multiple keys possible

[Dirk Gottschalk]

Hello.

Is it possible to sign a file with multiple keys?

For Example: John, Harry and Sally wrote a file, lets assume it is a
text file. Now all of them want to sign this file, so that when
verifying it, all three signatures are visible.

Is this possible?

I tried with --clearsign, but that doesn't work, because the former
signatures are disabled by the latest signing process.

Is there any way to add a signature instead of overriding the former
Signature?

Regards,
Dirk
