Class PdfDigitalSignatureHashAlgorithm

java.lang.Object

com.aspose.words.PdfDigitalSignatureHashAlgorithm

public class PdfDigitalSignatureHashAlgorithm
extends java.lang.Object

Specifies a digital hash algorithm used by a digital signature.

Examples:

Shows how to sign a generated PDF document.

 
 Document doc = new Document();
 DocumentBuilder builder = new DocumentBuilder(doc);
 builder.writeln("Contents of signed PDF.");

 CertificateHolder certificateHolder = CertificateHolder.create(getMyDir() + "morzal.pfx", "aw");

 // Create a "PdfSaveOptions" object that we can pass to the document's "Save" method
 // to modify how that method converts the document to .PDF.
 PdfSaveOptions options = new PdfSaveOptions();

 // Configure the "DigitalSignatureDetails" object of the "SaveOptions" object to
 // digitally sign the document as we render it with the "Save" method.
 Calendar calendar = Calendar.getInstance();
 calendar.set(2015, Calendar.JULY, 20);
 Date signingTime = calendar.getTime();
 options.setDigitalSignatureDetails(new PdfDigitalSignatureDetails(certificateHolder, "Test Signing", "My Office", signingTime));
 options.getDigitalSignatureDetails().setHashAlgorithm(PdfDigitalSignatureHashAlgorithm.RIPE_MD_160);

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

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