DIGITAL SIGNATURE AND DIGEST VERIFICATION
The general forms of rpm digital signature commands are
rpm --import PUBKEY ...
rpm {--checksig} [--nosignature] [--nodigest]
PACKAGE_FILE ...
The --checksig option checks all the digests and signatures contained
in PACKAGE_FILE to ensure the integrity and origin of the package. Note
that signatures are now verified whenever a package is read, and
--checksig is useful to verify all of the digests and signatures asso-
ciated with a package.
Digital signatures cannot be verified without a public key. An ASCII
armored public key can be added to the rpm database using --import. An
imported public key is carried in a header, and key ring management is
performed exactly like package management. For example, all currently
imported public keys can be displayed by:
rpm -qa gpg-pubkey*
Details about a specific public key, when imported, can be displayed by
querying. Here’s information about the Red Hat GPG/DSA key:
rpm -qi gpg-pubkey-db42a60e
Finally, public keys can be erased after importing just like packages.
Here’s how to remove the Red Hat GPG/DSA key
rpm -e gpg-pubkey-db42a60e
So, a rpm -qa ... to find the keys that RPM knows about, a rpm -qi ...
to find info about it (making doubly-sure you've got the right one),
then a rpm -e ... to erase a key you don't want to keep.
"apropos" is another command you might want to learn about. It searches
your system for manual files, and other files, related to your query.
Beginner's hints:
man apropos
man locate
man man
