Open up a browser and go to:

The GPG keys used to sign the RPM packages are in that directory.  That 
may also be the key used to sign the checksum files.  Here;s what I did 
on my system to check:

The bit that says "Good signature" seems to indicate that it was OK.

Hope that answers your question!
