Greetings all! I'm a big n00b when it comes to this stuff, so hopefully you guys and gals can edumacate me! I was recently fiddling around in my Google Chrome preferences folder and I stumbled upon the Keychain Access in Mac OS. I have a rather elementary understanding of the login and system certificates and their purpose, but could someone please tell me how "System Roots" certificates work? I browsed through the System Roots certificates on my Mac; and although they are all labeled valid, I am not sure if they are. For example, one of the certificates is named "EBG Elektronik Sertifika Hizmet Sağlayıcısı". Is this harmful in any way? I also screen-capped a portion of the list. If someone could please run their eyes over it and let me know if anything seems out of place, that would be greatly appreciated! http://img233.imageshack.us/img233/3962/screenshot20111103at628.png Thanks!
