Description of Digital Code Signing in Internet Explorer

• Microsoft Internet Explorer version 3.0, 4.0 for Windows 95

SUMMARY

Digital Code Signing is a standard used to help ensure that content and files you download from the Internet have come from trusted sources and have not been altered since their creation. This also provides additional protection against computer viruses.

MORE INFORMATION

Digital Code Signing can be used for downloadable files and ActiveX Web page content.

When a file or an ActiveX page is downloaded, a check is performed to determine if the file or content was signed by the publisher and whether or not the certificate used to sign the code is valid. You are prompted to continue downloading the file based on the information that is displayed.
