Hello, Perhaps I didn't explain properly what is my concern in this case.
The file I've provided as an example isn't really important. I've just wanted to point out that, for that file, which is signed by some (presumably commercial) service, Adobe Reader in Signature Advanced Properties shows a label saying: PAdES Signature Level: B-T For any of my documents, signed by PDFBox, Adobe Reader doesn't show that label. I wanted to ask for your opinion, does PDFBox provide sufficient funtionality needed to enable Adobe Reader to show PAdES Signature Level label in Advanced Properties for signed documents? I hope I now explained a little better. :-) Best regards, Predrag Sent from my ZX Spectrum 48K. -------- Original message -------- From: Tilman Hausherr <thaush...@t-online.de> Date: 26/11/2019 21:42 (GMT+01:00) To: users@pdfbox.apache.org Subject: Re: After adding validation information, Adobe Reader says Signature is not LTV enabled Hi, I can't create an LTV file, because this host doesn't exist: http://cloudid.netset.rs/aia/pksROOT.crt Tilman Am 26.11.2019 um 12:07 schrieb Predrag Stojković: > Hello, > > Thanks for all the changes related to FreeTSA, you've been extremely helpful. > > It's not directly related to the earlier LTV issues, but could you please > take a look at this document: > https://drive.google.com/open?id=14Wywy7PT7AzGWKPlZNnXmVNpMM-zt18Y > > The supplied document is not signed with Apache PDFBox, it's most likely > signed by some commercial library or service . > BUT, if you open the file in Adobe Reader, click on Signature Panel, right > click on signature, click on Show Signature Properties..., and then click on > Advanced Properties..., you can see that in Signature Details section there > is a label saying: > PAdES Signature Level: B-T > > When I sign the document with Apache PDFBox, even though adding validation > information now works after applying all the changes to PDFBox code you made, > and Adobe Reader in Signature Panel shows label Signature is LTV enabled, > this label about PadES Signature Level is still not shown. > > I appologize for putting up another tedious task, but could you investigate > somewhat on this matter? > > Thank you again and best regards, > Predrag > > -----Original Message----- > From: Tilman Hausherr [mailto:thaush...@t-online.de] > Sent: Sunday, November 24, 2019 11:41 AM > To: users@pdfbox.apache.org > Subject: Re: After adding validation information, Adobe Reader says Signature > is not LTV enabled > > Hi, > > I have been in a nice contact with the person operating freetsa, and (s)he > has now made several changes. > > However it turns out that our code needed some changes too, please look at > https://issues.apache.org/jira/browse/PDFBOX-4696# > and change the three files mentioned, or you will get endless loop or > recursions. > > Tilman > > Am 19.11.2019 um 10:55 schrieb Predrag Stojković: >> That is valuable information regarding TSA. >> Thank you again for your great efforts in resolving this issue. :) >> >> Best regards, >> Predrag >> >> -----Original Message----- >> From: Tilman Hausherr [mailto:thaush...@t-online.de] >> Sent: Sunday, November 17, 2019 3:11 PM >> To: users@pdfbox.apache.org >> Subject: Re: After adding validation information, Adobe Reader says >> Signature is not LTV enabled >> >> Am 14.11.2019 um 20:48 schrieb Tilman Hausherr: >>> My next step will be to sign and timestamp and validate a file with >>> freetsa to see if this works.
