例子

VBA：

Sub Example_TimeServer()
    ' This example attaches a digital signature and accompanying data to a file,
    ' and saves the file.

    Dim sp As AcadSecurityParams
    Set sp = GetInterfaceObject("AutoCAD.SecurityParams." + Left(AcadApplication.Version, 2))
    
    ' Attach a digital signature and timestamp it
    sp.Action = AcadSecurityParamsType.ACADSECURITYPARAMS_SIGN_DATA _
                + AcadSecurityParamsType.ACADSECURITYPARAMS_ADD_TIMESTAMP
    
    ' Certificate details follow
    sp.Subject = "Thawte Freemail Member"
    sp.Issuer = "Personal Freemail RSA 2000.8.30"
    sp.SerialNumber = "073848"
    sp.Comment = "This is now signed"
    sp.TimeServer = "NIST(time.nist.gov)"
    ' To set the TimeServer property, use a description followed by the Internet address in parentheses
    
    ThisDrawing.SaveAs "C:\MyDrawing.dwg", , sp
End Sub

可视化 LISP：

(vl-load-com)
(defun c:Example_TimeServer()
    ;; This example attaches a digital signature and accompanying data to a file,
    ;; and saves the file.
    (setq acadObj (vlax-get-acad-object))
    (setq sp (vlax-create-object (strcat "AutoCAD.SecurityParams." (substr (getvar "ACADVER") 1 2))))
  
    (vla-put-Visible acadObj :vlax-true)
    
    ;; Attach a digital signature and timestamp it
    (vla-put-Action sp (+ ACADSECURITYPARAMS_SIGN_DATA ACADSECURITYPARAMS_ADD_TIMESTAMP))
    
    ;; Certificate details follow
    (vla-put-Subject sp "Thawte Freemail Member")
    (vla-put-Issuer sp "Personal Freemail RSA 2000.8.30")
    (vla-put-SerialNumber sp "073848")
    (vla-put-Comment sp "This is now signed")
    (vla-put-TimeServer sp "NIST(time.nist.gov)")
    ;; To set the TimeServer property, use a description followed by the Internet address in parentheses

    (setq doc (vla-get-ActiveDocument acadObj))
    (vla-SaveAs doc "C:\\MyDrawing.dwg" acNative sp)
  
    (vlax-release-object sp)
