Encrypting the PDF will break the signature, so no, it's not possible. -----Original Message----- From: Jan Mynarik [mailto:[email protected]] Sent: Thursday, March 03, 2011 5:49 AM To: [email protected] Subject: [iText-questions] Sign and then encrypt ... and back
Hello! I would like to ask if it is possible to sign a document by one person, encrypt it by other ... and then decrypt and validate the signature. I tried it and haven't succeeded. The signature of signed document is validated but signature of decrypted document isn't. I understand that encrypting/decrypting changes the whole document but still was hoping that decrypt would return the document to its original state. Keep up the great work you are doing guys!
