Use Digital Signature Tool

This tutorial only applies to Xamarin.Android.

The Tools package comes with a basic DigitalSignature tool that allows signing with a specific keystore and password.

The DigitalSignature tool can be used with the UI components such as DocumentActivity and PdfViewCtrlTabHostFragment. You can also use the tool with PDFViewCtrl through ToolManager.

By default, signature tool without signing is used. You can switch to include signing as follows:

var tmBuilder = ToolManagerBuilder.From()
  .SetUseDigitalSignature(true)
  .SetDigitalSignatureKeystorePath("my_keystore_path")
  .SetDigitalSignatureKeystorePassword("my_keystore_password")
var builder = ViewerConfig.Builder()
var config = builder
  //...
  .ToolManagerBuilder(tmBuilder)
  .Build()

The signed signature is then saved to a separate file.

The built-in digital signature tool will continue to improve in the near future.
