But it is always a good idea to verify checksum independent of the download agent. sha1sum is what Fedora (and I believe the Fedora respins) use. There will be a file you can download from Fedora or the respin community that has the sha1dum in it. Put it is the same directory as the downloaded iso. Then use sha1sum with the checksum file as the arguement, and it will verify that what you have is genuine. man sha1sum (man page should also be available in yelp graphical viewer)
