Limitations

The approach in this project has the following limitations:

• The PdfDocumentProcessor class allows you to apply only one digital signature to a PDF document.
• The PdfDocumentProcessor removes existing signatures from a document when the file is saved. However, if you use PdfDocumentProcessor to apply a signature, it is retained.

Use the solution from this example for more flexible approach: How to Apply Multiple Signatures
