Great! The problema was doc.save(...) Now the PDF is certified. I would like to be LTV also. What are the things that make a signature LTV ? Thank you Damien and Diego! On Wed, Oct 19, 2016 at 6:09 PM, Damien Butaye wrote: > Hello Jonathan, > > Try also to use

In some Java code of different PDF Signatue framework, I saw the use of the "Perms" dictionnary to certify PDF. Do you have any idea if the "Perms" can help to see the blue ribbon? 2016-10-19 10:48 GMT+02:00 Damien Butaye : > Yes but in my case my certificate has the

Re: How to certify a PDF

Yes but in my case my certificate has the authorization to certify document (the cross is green beside the "Certify Document" in your previous printscreen). I wonder me if another information must be present in the PDF to show the blue ribbon?! 2016-10-18 17:40 GMT+02:00 Diego Azevedo

Hello Damien, I made a typo: dictionary.setItem("Reference", reference_*s*_); // Add Array to Signature dictionary There is no point in creating the array, add the "SigRef" dictionary to it... and not use the array on the "Sig" dictionary. So... just add the 'S' to the variable and

Re: How to certify a PDF

From what I'm reading on ISO 32000, the certification Signature is a normal signature, but with a DocMDP transform method. So the ou should do something like this: PDSignature signature = new PDSignature; [..] //do your thing COSDictinary dictionary = signature.getCOSObject();
