Class PdfDigitalSignatureDetails

java.lang.Object

com.aspose.words.PdfDigitalSignatureDetails

public class PdfDigitalSignatureDetails
extends java.lang.Object

Contains details for signing a PDF document with a digital signature.

Remarks:

At the moment digitally signing PDF documents is only available on .NET 3.5 or higher.

To digitally sign a PDF document when it is created by Aspose.Words, set the PdfSaveOptions.getDigitalSignatureDetails() / PdfSaveOptions.setDigitalSignatureDetails(com.aspose.words.PdfDigitalSignatureDetails) property to a valid PdfDigitalSignatureDetails object and then save the document in the PDF format passing the PdfSaveOptions as a parameter into the Document.save(java.lang.String, com.aspose.words.SaveOptions) method.

Aspose.Words creates a PKCS#7 signature over the whole PDF document and uses the "Adobe.PPKMS" filter and "adbe.pkcs7.sha1" subfilter when creating 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");
