[pkg-gnupg-maint] Bug#1001331: gpg: Provide interface to inspect (detached) signatures

[Guillem Jover]

Package: gpg
Version: 2.3.1-1
Severity: wishlist

Hi!

With the latest debsig-verify I switched one of its gpg uses away from
«--list-packets» to «--with-colons --show-keys». But the remaining one
I cannot stop using as I do not know of a publicly supported interface
to inspect a (detached) signature to get its issuer fingerprint or
keyid.

Given that using «--list-packets» is very strongly discouraged from
other tools, it would be nice if there was a replacement for that use,
so that I can move away from it.

Thanks,
Guillem
