Class PdfDigitalSignatureHashAlgorithm

  • java.lang.Object
    • com.aspose.words.PdfDigitalSignatureHashAlgorithm
public class PdfDigitalSignatureHashAlgorithm 
extends java.lang.Object

Utility class containing constants. Specifies a digital hash algorithm used by a digital signature.

Example:

Shows how to sign a generated PDF using Aspose.Words.
Document doc = new Document();
DocumentBuilder builder = new DocumentBuilder(doc);
builder.writeln("Signed PDF contents.");

// Load the certificate from disk
// The other constructor overloads can be used to load certificates from different locations
CertificateHolder certificateHolder = CertificateHolder.create(getMyDir() + "morzal.pfx", "aw");

// Pass the certificate and details to the save options class to sign with
PdfSaveOptions options = new PdfSaveOptions();
Date signingTime = new Date();
options.setDigitalSignatureDetails(new PdfDigitalSignatureDetails(certificateHolder, "Test Signing", "Aspose Office", signingTime));

// We can use this attribute to set a different hash algorithm
options.getDigitalSignatureDetails().setHashAlgorithm(PdfDigitalSignatureHashAlgorithm.SHA_256);

Assert.assertEquals(options.getDigitalSignatureDetails().getReason(), "Test Signing");
Assert.assertEquals(options.getDigitalSignatureDetails().getLocation(), "Aspose Office");
Assert.assertEquals(options.getDigitalSignatureDetails().getSignatureDate(), signingTime);

doc.save(getArtifactsDir() + "PdfSaveOptions.PdfDigitalSignature.pdf");
