Unclear how to use NFPM signing with password protected GPG private key

[jsirianni]

We are trying to use Goreleaser nfpm to sign Deb and RPM packages. This works if we use a GPG key without a password. It does not work with a password, even when NFPM_PASSPHRASE is set in the environment. I get the error "npgp: invalid argument: signing key is encrypted"

Can you provide an example or clarify how the GPG key is expected to be formatted and what role the passphrase plays?
