getComments()

public String getComments()

Specifies comments on the digital signature. Default value is empty string.

Examples:

Shows how to digitally sign documents.


 // Create an X.509 certificate from a PKCS#12 store, which should contain a private key.
 CertificateHolder certificateHolder = CertificateHolder.create(getMyDir() + "morzal.pfx", "aw");

 // Create a comment and date which will be applied with our new digital signature.
 SignOptions signOptions = new SignOptions();
 {
     signOptions.setComments("My comment");
     signOptions.setSignTime(new Date());
 }

 // Take an unsigned document from the local file system via a file stream,
 // then create a signed copy of it determined by the filename of the output file stream.
 InputStream streamIn = new FileInputStream(getMyDir() + "Document.docx");
 try {
     OutputStream streamOut = new FileOutputStream(getArtifactsDir() + "DigitalSignatureUtil.SignDocument.docx");
     try {
         DigitalSignatureUtil.sign(streamIn, streamOut, certificateHolder, signOptions);
     } finally {
         if (streamOut != null) streamOut.close();
     }
 } finally {
     if (streamIn != null) streamIn.close();
 }
 

Returns: java.lang.String - The corresponding java.lang.String value.

getDecryptionPassword()

public String getDecryptionPassword()

The password to decrypt source document. Default value is empty string.

Remarks:

If OOXML document is encrypted, you should provide decryption password to decrypt source document before it will be signed. This is not required for documents in binary DOC format.

Examples:

Shows how to sign encrypted document file.


 // Create an X.509 certificate from a PKCS#12 store, which should contain a private key.
 CertificateHolder certificateHolder = CertificateHolder.create(getMyDir() + "morzal.pfx", "aw");

 // Create a comment, date, and decryption password which will be applied with our new digital signature.
 SignOptions signOptions = new SignOptions();
 {
     signOptions.setComments("Comment");
     signOptions.setSignTime(new Date());
     signOptions.setDecryptionPassword("docPassword");
 }

 // Set a local system filename for the unsigned input document, and an output filename for its new digitally signed copy.
 String inputFileName = getMyDir() + "Encrypted.docx";
 String outputFileName = getArtifactsDir() + "DigitalSignatureUtil.DecryptionPassword.docx";

 DigitalSignatureUtil.sign(inputFileName, outputFileName, certificateHolder, signOptions);
 

Returns: java.lang.String - The corresponding java.lang.String value.

getProviderId()

public UUID getProviderId()

Specifies the class ID of the signature provider. Default value is Empty (all zeroes) Guid.

Remarks:

The cryptographic service provider (CSP) is an independent software module that actually performs cryptography algorithms for authentication, encoding, and encryption. MS Office reserves the value of {00000000-0000-0000-0000-000000000000} for its default signature provider.

The GUID of the additionally installed provider should be obtained from the documentation shipped with the provider.

In addition, all the installed cryptographic providers are enumerated in windows registry. It can be found in the following path: HKLM\SOFTWARE\Microsoft\Cryptography\Defaults\Provider. There is a key name “CP Service UUID” which corresponds to a GUID of signature provider.

Examples:

Shows how to sign a document with a personal certificate and a signature line.

 signatureLine.setProviderId(UUID.fromString("CF5A7BB4-8F3C-4756-9DF6-BEF7F13259A2"));

 Assert.assertFalse(signatureLine.isSigned());
 Assert.assertFalse(signatureLine.isValid());

 doc.save(getArtifactsDir() + "DocumentBuilder.SignatureLineProviderId.docx");

 Date currentDate = new Date();

 SignOptions signOptions = new SignOptions();
 signOptions.setSignatureLineId(signatureLine.getId());
 signOptions.setProviderId(signatureLine.getProviderId());
 signOptions.setComments("Document was signed by vderyushev");
 signOptions.setSignTime(currentDate);

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

 DigitalSignatureUtil.sign(getArtifactsDir() + "DocumentBuilder.SignatureLineProviderId.docx",
         getArtifactsDir() + "DocumentBuilder.SignatureLineProviderId.Signed.docx", certHolder, signOptions);

 // Re-open our saved document, and verify that the "IsSigned" and "IsValid" properties both equal "true",
 // indicating that the signature line contains a signature.
 doc = new Document(getArtifactsDir() + "DocumentBuilder.SignatureLineProviderId.Signed.docx");
 Shape shape = (Shape) doc.getChild(NodeType.SHAPE, 0, true);
 signatureLine = shape.getSignatureLine();

 Assert.assertTrue(signatureLine.isSigned());
 Assert.assertTrue(signatureLine.isValid());
 

Returns: java.util.UUID - The corresponding java.util.UUID value.
