java.lang.Object

com.aspose.cells.DigitalSignatureCollection

All Implemented Interfaces:

java.lang.Iterable

public class DigitalSignatureCollection
extends java.lang.Object
implements java.lang.Iterable

Provides a collection of digital signatures attached to a document.

Example

The following example shows how to validate digital signature.

 
         //workbook from a signed source file
         Workbook signedWorkbook = new Workbook("signedFile.xlsx");
         //wb.IsDigitallySigned is true when the workbook is signed already.
         System.out.println(signedWorkbook.isDigitallySigned());
         //get digitalSignature collection from workbook
         DigitalSignatureCollection existingDsc = signedWorkbook.getDigitalSignature();
         for (DigitalSignature existingDs : (Iterable<DigitalSignature>) existingDsc)
         {
             System.out.println(existingDs.getComments());
             System.out.println(existingDs.getSignTime());
             System.out.println(existingDs.isValid());
         }
