Is it possible to sign a DEB or RPM?

Great tool, especially when used as a Github Action.

I wonder if it's possible to sign the packages with PGP? There seems to be support to do so in NFPM, but I couldn't find any references in the code, although I don't speak golang.

Doesn't look like it currently. Definitely would be nice to see though IMHO!
