Thawte Code Signing Certificates create a unique digital signature with identification information about the publisher of the code and proof of the code’s integrity. Microsoft applications such as Internet Explorer®, Exchange, Outlook® and Outlook® Express have security features to check for a digital signature and recommend whether or not code should be trusted.

When a user encounters unsigned or self-signed executables, a security warning pops up or content fails to load, depending on the user’s security settings.

When a signed executable is encountered, a pop-up notification shows the verified identity of the publisher and the user decides whether or not to trust the code.

In Microsoft Windows, signed code has an additional Properties tab that displays information about the signature. The user can see who the application came from and be reminded that the application hasn't been changed since it was signed
