Install the Certificates

The Windows Internet Information Server (IIS)supports Secure Sockets Layer (SSL) communications. A whole Web site, a folder on the Web site, or a particular file that is located in a folder on the site can require a secure SSL connection. However, before the Web server can support SSL sessions, a Web site certificate must be installed.

You can use one of the following methods to install a certificate in IIS:

• Make an online request by using the IIS Web Server Certificate Wizard and install the certificate at the time of the request.
• Make an offline request by using the IIS Web Server Certificate Wizard and obtain and install the certificate later.
• Request a certificate without using the IIS Web Server Certificate Wizard.

To install the Web site certificate, you must complete the following tasks:

• Import the certificate into the computer's certificate store.
• Assign the installed certificate to the Web site.
