VerifyFile Method

 

Verifies the digital signature encapsulated in a script.

Syntax

Object.VerifyFile (FileName, ShowUI)

Arguments

• object
  Scripting.Signer

• FileName
  A string containing the name of the script file.

• ShowUI
  A Boolean value. If the ShowUI argument is false, then the Scripting.Signer object determines whether a trusted source provided the signature without prompting the user. If it is true then the Scripting.Signer object may create dialog boxes to prompt the user if there is not sufficient information to determine trust.

  Note

  On some operating systems, the operating system also creates a dialog box if the flag is on, the file is trusted, and you have not already checked the "Always trust " option.

Legacy Code Example

Description

The following example demonstrates signature checking using the command-line argument processing features.

<job>
<runtime>
<named name="file" helpstring="the file to sign" required="true" type="string"/>
<named name="UI" helpstring="produce user interface for untrusted scripts" required="false"/>
</runtime>
<script language="vbscript">
Dim Signer, File, UI, OK
If Not WScript.Arguments.Named.Exists("file") Then
     WScript.Arguments.ShowUsage
     WScript.Quit
End If
Set Signer = CreateObject("Scripting.Signer")
File = WScript.Arguments.Named("file")
UI   = WScript.Arguments.Named.Exists("ui")
OK = Signer.VerifyFile(File, UI)
If OK Then
     WScript.Echo File & " is trusted."
Else
     WScript.Echo File & " is NOT trusted."
End If
</script>
</job>
