To use I-Billing, your web browser must use 128-bit encryption. Even the newest web browsers may not have this feature installed. If you are unable to use the I-billing web site, it may be because you do not have the 128-bit encryption feature installed. Use the following instructions to check your web browser for this feature.

Microsoft Internet Explorer 4.0 or higher:

1. Open up your browser window.
2. Click on the word "Help" at the top of the browser window.
3. Click on "About Internet Explorer."
4. Look for the words "Cipher Strength" in the window that opens up when you click on "About Internet Explorer". If you have 128 bit encryption, it will say "128-bit" to the right of "Cipher Strength."

Microsoft Internet Explorer is less than version 4.0:

1. Download the current version of Microsoft Internet Explorer. Click here to download the latest version: Microsoft Internet Explorer.
2. Follow the directions above for "Microsoft Internet Explorer 4.0 or higher."

Netscape Navigator:

I-billing should work with Netscape Navigator or Netscape Communicator if it has the 128-bit encryption feature. However, you may experience problems with versions 6 or higher, even if 128-bit encryption is installed. To download versions prior to 6, go to the Netscape Archived Products page. To find out if the version you have installed now has the 128-bit encryption feature, follow these instructions:

1. Open up your browser window.
2. Click on the word "Help" at the top of the browser window.
3. Click on "About Navigator" or "About Communicator."
4. When you click on "About Navigator" or "About Communicator" a page will open that tells you about your browser version. In this page, look for this text:

   This version supports U.S.
   security with RSA Public Key
   Cryptography, MD2, MD5,
   RC2-CBC, RC4, DES-CBC,
   DES-EDE3-CBC.

If you don't have this text, you will need to upgrade your Netscape browser.
To download a version prior to version 6 that has 128-bit encryption, go to the Netscape Archived Products page.

America Online:

1. If you are using America Online, use the Microsoft Internet Explorer browser that comes with it. Check the Microsoft Internet Explorer browser to see if it has 128-bit encryption by following the instructions for "Microsoft Internet Explorer 4.0 or higher" above.
2. After checking the Microsoft Internet Explorer browser to see if it has 128-bit encryption, log on to America Online. Leave AOL open and open the Microsoft Internet Explorer browser. Use the Microsoft Internet Explorer browser to log in to the I-billing system.
