A Microsoft security technology that certifies the identity of the publisher of software to ensure the software has not been tampered with.
An Internet software publisher first obtains a digital certificate from a certificate authority (CA) and uses Authenticode signing tools to digitally sign his or her application.
When a user tries to download the application from the Internet, client-side Authenticode software in Microsoft Internet Explorer and Microsoft Windows 98 displays the publisher’s certificate information to help the user make a more informed decision about whether to install the software on his or her machine.
Authenticode can be used to sign Microsoft ActiveX controls, .cab files, Java applets, or any other executable files.
Note: The Windows 98 implementation of Authenticode enables you to check online certificate revocation.
