Hi,
Can u please tell me what may be the possibilities to get invalid signature
after signature insertion resulting into invalid pdf.?What may be the changes
pdfbox do that are disallowed by acrobat due to which it results in invalid
pdf. If pdf with invisible signature is signed can it generate valid pdf with
signature? Is there any role of Bouncycastle to produce valid pdf? I tried to
remove unwanted trailer entry but didn't work. Thanks in advance.
