Hello to the team, This is the description of what I am trying to do : * I prepared a PDF for signature and I sent the digest to a provider. * The provider signs the digest and sends me back the result. => I do not know how to add it into the document. I tried something but it does not work, there is an error when opening the document in acrobat.
Maybe with the code it will be easier : * Prepared PDF is "DeferSigningExternal" Class using only one unittest. At the end I get the "Digest B64" that I send to the provider. I copy the date used in this PDF for future... * I use "DeferSigningExternalSign" to attach the signature into the PDF. As I am using the same PDF I consider that I can restart the process on the original PDF from scratch using the previous date, the offset is the same because I am not changing anything. So I fix the date at the beginning in dateInput and I set the signed hash with the answer of my provider in digestSigned. I probably forgot something that I did not understand yet about signatures and all that stuffs :D. Maybe I need to add the Certificate of the user to the PDF,... I do not know. I do not have the private key, I can get the certificate. This is like a prototype. Next I will try to do the same with Pades... My provider told me that the signed hash is in PKCS#1 format using PKCS#1 v1.5 padding. Thanks a lot for your help. I was thinking of using DSS if it is simpler... I had a look at the testaread-sd-dss5 of MKL. Best regards, Fred
