Important: In order to create a digital signature, you must first have a valid PKCS#12 certificate (*.pfx) file. To use the code below, change the path and file name to point to your PFX, and change "password" to the password for your PFX file. You can use a third-party digital ID, or create a self-signed certificate. For information on creating a self-signed certificate, see the Adobe Acrobat Help topic "Create a self-signed digital ID." You can also create a PFX file from the Visual Studio command line. For more information and links to SDK downloads, see http://www.source-code.biz/snippets/vbasic/3.htm. |
The following code samples assume that you have a report variable rpt, and that you have dragged the PDFExport object onto your form.
To add an invisible signature
The following example shows what the code for adding an invisible signature looks like. Replace the path and filename and password of the Certificate with your certificate information.
To write the code in Visual Basic.NET
| Visual Basic.NET code. Paste INSIDE the Form Load event. |  Copy Code |
|---|---|
Me.PdfExport1.Signature.VisibilityType = DataDynamics.ActiveReports.Export.Pdf.Signing.VisibilityType.Invisible ' Set certificate & password. Me.PdfExport1.Signature.Certificate = New Security.Cryptography.X509Certificates.X509Certificate2(Application.StartupPath & "\..\..\certificate.pfx", "password") ' Signature items. Me.PdfExport1.Signature.Reason = New DataDynamics.ActiveReports.Export.Pdf.Signing.SignatureField(Of String)("I agree.") Me.PdfExport1.Signature.Location = New DataDynamics.ActiveReports.Export.Pdf.Signing.SignatureField(Of String)("Japan") Me.PdfExport1.Export(rpt.Document, Application.StartupPath & "\..\..\VisibilityType_Invisible.pdf") | |
| C# code. Paste INSIDE the Form Load event. | Copy Code |
|---|---|
String path = Path.Combine(Application.StartupPath, "\..\..\certificate.pfx"); String output = “output.pdf”; // Set certificate & password. this.pdfExport1.Signature.Certificate = new System.Security.Cryptography.X509Certificates.X509Certificate2(path, "password"); // Signature items. this.pdfExport1.Signature.Reason = new DataDynamics.ActiveReports.Export.Pdf.Signing.SignatureField <String>("I agree."); this.pdfExport1.Signature.Location = new DataDynamics.ActiveReports.Export.Pdf.Signing.SignatureField <String>("Japan"); this.pdfExport1.Export(rpt.Document, output); | |
To add a visible signature with the time stamp
The following example shows what the code for adding a visible signature with the time stamp looks like. Replace the path and filename and password of the Certificate with your certificate information, and replace the time stamping authority (TSA) URL with that of your TSA.
 |
Note: You must purchase a volume-based registration at an actual TSA for your applications. |
