Step 3 Signing the CAB File

When IE 4.0 and later versions are running at the default security level, any object identified by the OBJECT object on an HTML page must be digitally signed.

A digital signature associates a software vendor’s name and a unique public key with a file that contains an ActiveX object.

The test certificate generated before can be used to sign the CAB file.

Use the signcode.exe utility (and accompanying wizard), to sign the .cab file

C:\CAB&SIGN\Signcode

If the signcode is successful, it will have embedded a PKCS7 certificate in the cab file.

If you package your control in one or more .cab files, each file must be digitally signed.
