12 Chapter 3. Building Custom Packages

gpg --export -a ’Your Name’ > public_key.txt

Your public key is written to the ﬁle public_key.txt.

This public key is quite important. It’s the key that must be deployed to all client systems

that receive custom software through up2date. Techniques for deploying this key across

an organization are covered in the Red Hat Network Client Conﬁguration Guide.

3.2.2. Signing packages

Before you can sign packages, you need to conﬁgure your ~/.rpmmacros ﬁle to include

the following:

%_signature gpg

%_gpg_name B7085C8A

Replace the _gpg_name key ID value of B7085C8A with the key ID from your GPG

keyring that you use to sign packages. This value tells RPM which signature to use.

To sign the package package-name-1.0-1.noarch.rpm, use the following com-

mand:

rpm --resign package-name-1.0-1.noarch.rpm

Enter your passphrase. To make sure the package is signed, use the following command:

rpm --checksig -v package-name-1.0-1.noarch.rpm

You should see the phrase Good signature from "Your Name" in the output, with

Your Name replaced with the name associated with the signing key.
