15.3.1. Importing Keys
To verify Red Hat packages, you must import the Red Hat GPG key. To do so, execute the following command at a shell prompt:
rpm --import /usr/share/rhn/RPM-GPG-KEY
To display a list of all keys installed for RPM verification, execute the command:
rpm -qa gpg-pubkey*
For the Red Hat key, the output includes:
gpg-pubkey-db42a60e-37ea5438
To display details about a specific key, use rpm -qi followed by the output from the previous command:
rpm -qi gpg-pubkey-db42a60e-37ea5438
