Hello there. I've just downloaded the CentOS v7.0 via torrent and am  
trying to verify the gpg signature for the file with hashes. When I do  
"gpg --verify sha256sum.txt.asc" I get the key ID of F4A80EB5. Then I'm  
trying to get the public key with "gpg --keyserver pgp.mit.edu --recv-keys  
F4A80EB5" command. The gpg returns error of "no valid OpenPGP data found".  
Does anyone have an idea of why the public key isn't there? Is there  
another keyserver I should try?

The torrent link came from here -- http://goo.gl/YctkmI (The first DVD one)
