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");
