Microsoft Internet Explorer supports two levels of encryption, 40-bit and 128-bit. The standard 40-bit versions include Server Gated Cryptography (SGC) technology. With SGC technology, international customers can conduct 128-bit transactions with banks and financial institutions (that support SGC) around the world.
Internet Explorer with 40-bit (SGC) encryption is available worldwide, but Internet Explorer with full 128-bit encryption is available in the United States (or its territories, possessions and dependencies) and Canada only. If you have installed Internet Explorer with 40-bit (SGC) encryption and are in the United States (or its territories, possessions and dependencies) or Canada, you can upgrade to Internet Explorer with full 128-bit encryption.
To upgrade Internet Explorer to 128-bit encryption, visit the following Microsoft Web site, and then follow the instructions that appear on the screen:
: To upgrade Internet Explorer 3.02 on Windows NT 4.0, download and install the 128-bit version of the Windows NT 4.0 Service Pack 3 (SP3) or later.
You may not be able to download the 128-bit version upgrade for all operating systems. If an upgrade is not available for your operating system, you must download a 128-bit browser only (or browser and components) package from this link and reinstall it over your current version.
The 128-bit versions of Internet Explorer are no longer available from Microsoft on CD-ROM.
In January 2000, the United States government issued new export regulations. Based on these regulations, Microsoft can deliver strong encryption products to all its customers worldwide except to U.S.-embargoed destinations. With strong encryption, customers improve their security and help protect data communications that they conduct over the Internet and over private networks. By default, most current Microsoft products that support encryption contain strong encryption.
