Using digital signature tool in Android

For Android, available in the full version of the library only. See Apryse full or standard?

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 PdfViewCtrlTabHostFragment2 . You can also use the tool with PDFViewCtrl through ToolManager .

Digital Signature

By default, the signature tool does not sign with a certificate. Certificate-based signatures can be enabled using ToolManagerBuilder which will add a certificate picker and password input field to the signature UI flow.

Alternatively you can define a certificate file and password in ToolManagerBuilder. This will disable the additional signing flow for digital signatures and use the specified certificate instead.

ToolManagerBuilder tmBuilder = ToolManagerBuilder.from()
    // Optionally specify a default certificate file and password
ViewerConfig.Builder builder = new ViewerConfig.Builder();
ViewerConfig config = builder

The signed document is then saved to a separate file.
