digitalSignatures property

Document.digitalSignatures property

Gets the collection of digital signatures for this document and their validation results.

get digitalSignatures(): Aspose.Words.DigitalSignatures.DigitalSignatureCollection

Remarks

This collection contains digital signatures that were loaded from the original document. These digital signatures will not be saved when you save this Document object into a file or stream because saving or converting will produce a document that is different from the original and the original digital signatures will no longer be valid.

This collection is never null. If the document is not signed, it will contain zero elements.

Examples

Shows how to validate and display information about each signature in a document.

const doc = new aw.Document(base.myDir + "Digitally signed.docx");

for (var i = 0; i < doc.digitalSignatures.count; i++) {
  const signature = doc.digitalSignatures.at(i);
  //console.log(`${signature.isValid ? "Valid" : "Invalid"} signature: `);
  //console.log(`\tReason:\t${signature.comments}`);
  //console.log(`\tType:\t${signature.signatureType}`);
  //console.log(`\tSign time:\t${signature.signTime}`);
  /*
  TODO: digitalSig.certificateHolder.certificate of X509Certificate2 type is not supported by Node.js.
  console.log(`\tSubject name:\t${signature.certificateHolder.certificate.subjectName}`);
  console.log(`\tIssuer name:\t${signature.certificateHolder.certificate.issuerName.name}`);
  */
  //console.log(`\r\n`);
}
