The public key is used if you need to authenticate to any of our services over SSH. This includes commit access for CVS and other code repositories or any shell access to our machines. We currently require RSA keys. You'll want to have your private key available on any machine that you use to SSH or commit code from. The public key is only needed on the machines that will be accepting your private key (which is why we ask for it). > In regards to the certificate, it requests I add this to a particular > location in the system.

This certificiate is currently only used to authenticate to koji and plague, the buildsystems for Fedora and EPEL, although we're considering using key authentication in more places in the future. Right now, you'll only need a copy of it if you plan on becoming a package maintainer. > Being new to Linux, I am thrilled to to have membership in > fedoraproject, as I have found linux nearly superior to windows in many > areas.
