We need to add a signature field to the Generated PDF file and another application will sign the file

We are having requirement to generate PDF from a word document, after that we need to provide Digital Signature fields with in the Generated PDF. Currently we are using Interop for PDF generation and ITextSharp for providing digital signature fields and locking the document.

We are evaluating Aspose.Words and Aspose.PDF to achieve both functionalities using Aspose components

Currently we were able to succeed to generating PDF Files on demand using Aspose.Words. However We did not find sample code/ Option to Add digital Signature Fields with in the generated PDF using Aspose.PDF component

We would like to know whether Aspose.Pdf provide Adding digital Signature fields to PDF or Not?

Please see the attached PDF for the digital signature blocks. The attached PDF is created using Aspose.Words and digital signature blocks/fields are created using iTEXTSharp. We are looking/checking this similar functionality available within Aspose.Pdf.

Hi Ramesh,


Thanks for using our products and sorry for the delayed response.

I am pleased to share that Aspose.Pdf for .NET supports the feature to add Digital signatures to PDF documents. Please visit the following link for further details on Add Digital Signature in a PDF File (Facades)

Hi Nayyer Shahbaz,

Thanks for update. The link you shared is referring to applying signature to a PDF. But in our case we want to provide empty signature blocks within the PDF. The signing will be done later part.




Hi Ramesh,


In case you only need to add Signature field to PDF file, please try using the introductions specified over Add Form Field in an Existing PDF file (Facades) (you simply need to use Signature value from FieldType enumeration).
