PdfDigitalSignatureDetails class
PdfDigitalSignatureDetails class
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.digitalSignatureDetails 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() 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.
