B.3.2. Verifying Signature of Packages
To check the GnuPG signature of an RPM file after importing the builder's GnuPG key, use the following command (replace <rpm-file> with the file name of the RPM package):
rpm -K <rpm-file>
If all goes well, the following message is displayed:
md5 gpg OK. This means that the signature of the package has been verified, that it is not corrupt, and therefore is safe to install and use.
