bal commented on PDFBOX-4609: ----------------------------- i had implemented the signatureinterface that why signature is attached in pdf. i tried to implement the sign() method in the signatureinterface derived class but couldn't create the keystore as in java which contains the alias and the pin . The bouncy castle example shows it is used to create the pkcs signature, i already have signature in pkcs format. It is not usable for me for the valid signature. Is another options to pass the correct input to sign method for valid signature? > At least one signature is invalid > ---------------------------------- > > Key: PDFBOX-4609 > URL: https://issues.apache.org/jira/browse/PDFBOX-4609 > Project: PDFBox > Issue Type: Wish > Components: .NET > Affects Versions: 1.8.15 > Reporter: bal > Priority: Major > Attachments: Debug.txt, keystore.p12 > > > I am getting signature is invalid error in the signature panel of pdf after > pkcs 7 signature insertion.
