It's not possible to do a two step signing. To be able to do that requires some source modifications.

In the tutorial, the step of generating the hash, signing it and them given the result to PDF is done in the same program. I need to use two distinct programs to sign one PDF file: one to generate the hash and the other to inject the signed hash into the PDF file (following the tutorial instructions). I have tried to split the tutorial code in two but the signature placed on resulting PDF is not recognized by Acrobat Reader. It seams the content of PdfSignatureAppearance.getRangeStream() is not the same in consecutive executions, generating different hash values for the same content. How can this be done?
