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
