$> rpm --checksig package_name.rpm

Example:

$> rpm --checksig mysql-community-server-8.0.33-1.el8.x86_64.rpm
mysql-community-server-8.0.33-1.el8.x86_64.rpm: digests signatures OK

$> gpg --export -a 3a79bd29 > 3a79bd29.asc
$> rpm --import 3a79bd29.asc

Alternatively, rpm also supports loading the key directly from a URL:

$> rpm --import https://repo.mysql.com/RPM-GPG-KEY-mysql-2022
