That will also be available right after the visible signatures.

Subject: [iText-questions] PDF digital signature

Hi,

 

I started using iText to try PDF digital signature.

I successfully signed a PDF document using the "PdfStamper.createInvisibleSignature" api.

If I try to add a new signature to the already signed document, the Acrobat viewer shows me the two signatures, but it says that the first signature is invalid "(byte range of signature is invalid)".

 

I have analyzed the code, it seems that the ByteRange property of the first signature is not updated when the second signature is added in the PDF document.

 

Does the iText library supports multiple signatures ?

 

Thanks in advance

 

Greetings

Giuseppe
