Sorry, I'm kinda new to all this certificate talk. I just knew I needed an SSL cert for encrypting our websites and one that customers' browsers would know and trust.

When you go to export a certificate in IIS, the wizard has a checkbox for exporting "extended properties". I can't find anywhere what this is referring to and whether I should check it or not.

IIS is Internet Information Services, the web server included with Windows Server operating systems. All current versions are built on a modular architecture; modules can be added or removed individually so that those required for specific functionality are installed. The full installation of IIS includes HTTP, security, content, compression, caching, logging and diagnostics.

HTTPS is a protocol for secure communication over a computer network which is widely used on the Internet. HTTPS consists of communication over Hypertext Transfer Protocol (HTTP) within a connection encrypted by Transport Layer Security (TLS) or its predecessor, Secure Sockets Layer (SSL).

HTTPS is widely used for protecting page authenticity on all types of websites, securing accounts and keeping user communications, identity and web browsing private.
