Checking for a Security Certificate

Starting with Word 2000, you could "digitally sign" your documents and templates with a security certificate. Technically, it is the VBA projects attached to documents and templates that can be signed. In your macros you may want to verify that the certificate is in place. Checking for the signature programmatically can make it easier to manage the overall security efforts of a company.

The property you can use for this purpose is VBASigned. You can use it as follows:

Documents.Open FileName:="D:\dotfiles\temp.dot"
If Not ActiveDocument.VBASigned Then
    MsgBox "Warning! This document has not been digitally signed.", _
      vbCritical, "Digital Signature Warning"
End If

The VBASigned property will be either True or False, depending on whether the document (in this case a template) has been signed.

Note:
