One topic this chapter doesn t treat in detail is SSL (Secure Sockets Layer) connections. These technologies are supported by IIS and are really independent from ASP.NET programming. However, they are an important ingredient in creating a secure website. Essentially, certificates allow you to demonstrate that your site and your organization information are registered and verified with a certificate authority. This generally encourages customer confidence, although it doesn t guarantee the company or organization acts responsibly or fairly. A certificate is a little like a driver s license it doesn t prove you can drive, but it demonstrates that a third party (in this case, a department of the government) is willing to attest to your identity and your qualifications. Your web server requires a certificate in order to use SSL, which automatically encrypts all the information sent between the client and server. To add a certificate to your site, you first need to purchase one from a certificate authority. These are some well-known certificate authorities: VeriSign (http://www.verisign.com) GeoTrust (http://www.geotrust.com) GlobalSign (http://www.globalsign.com) Thawte (http://www.thawte.com)

The first step in the process of getting a certificate is to e-mail a certificate request for your web server. IIS Manager allows you to create a certificate request automatically.

For the algebraic equation math problem, look at the Math Problem 3 section toward the bottom of the worksheet, as shown in Figure 1-8.

The exact process depends on the version of IIS that you have installed. In IIS 5 (the version included with Windows XP) or IIS 6 (the version included with Windows Server 2003), follow these steps: 1. Launch IIS Manager by opening the Start menu and choosing Settings Control Panel Administrative Tools Internet Information Services. 2. Expand your computer, then the Web Sites group, and then expand the Default Web Site item to see all the virtual directories on your web server. 3. Right-click the virtual directory for your website and choose Properties. 4. Under the Directory Security tab, you ll find a Server Certificate button. Click this button to start the Web Server Certificate wizard. In IIS 7 (the version included with Windows Vista and Windows Server 2008), follow these steps: 1. Launch IIS Manager by opening the Start menu and choosing Settings Control Panel Administrative Tools Internet Information Services (IIS) Manager. 2. Select the first item in the tree in IIS Manager, which is your computer. In the Features area on the right, double-click the Server Certificates icon. 3. In the Actions pane, click Create Certificate Request to start the Request Certificate wizard (shown in Figure 20-13).

[PostsTag] => Array ( [id] => [post_id] => 1 [tag_id] => 1 ) ) ) )

The Web Server Certificate wizard and the Request Certificate wizard serve the same purpose. They collect some basic information, such as your address, the strength of encryption key you would like (the higher the bit length, the stronger the key), and so on. At the end of the process, you ll create a key request. You can save the generated file as a text file, but you must ultimately e-mail it to a certificate authority. The following is a sample (slightly abbreviated) request file: Webmaster: administrator@certificatecompany.com Phone: (555) 555-5555 Server: Microsoft Key Manager for IIS Version 4.0 Common-name: www.yourcompany.com Organization: YourOrganization -----BEGIN NEW CERTIFICATE REQUEST----MIIB1DCCAT0CAQAwgZMxCzAJBgNVBAYTAlVTMREwDwYDVQQIEwhOZXcgWW9yazEQ MA4GA1UEBxMHQnVmZmFsbzEeMBwGA1UEChMVVW5pdmVyc2l0eSBhdCBCdWZmYWxv MRwwGgYDVQQLExNSZXNlYXJjaCBGb3VuZGF0aW9uMSEwHwYDVQQDExh3d3cucmVz ZWFyY2guYnVmZmFsby5lZHUwgZ8wDQYJKoZIhvcNAQEBBQADgY0AMIGJAoGBALJO hbsCagHN4KMbl7uz0GwvcjJeWH8JqIUFVFi352tnoA15PZfCxW18KNtFeBtrb0pf -----END NEW CERTIFICATE REQUEST----The certificate authority will return a certificate that you can install according to its instructions.

If you don t want to go to the trouble of buying a certificate, you can create a test certificate to use with your application. However, test certificates aren t suitable for real, live websites, because they lead to lots of browser security warnings (which is sure to scare away your users). IIS 7 (the version included with Windows Vista) makes it easy to create and use a test certificate. You can find instructions at http://tinyurl.com/2hndyq. You can create a test certificate for previous versions of IIS with a little more work using the makecert.exe command line tool. For more information, look up makecert.exe in the index of Visual Studio Help.
