I am getting an error as below,
Error message screenshot
I am opening pdf file by below link

The PDF is corrupt, ending in the middle of a stream. The last object starts with
10 0 obj^M
<<^M
/Filter [/FlateDecode ]^M
/Length 465325^M
>>^M
stream^M
This stream should have 465325 bytes of binary data followed by and endstream marker. But the file end abruptly mid-stream after about 43475 bytes of data, with no endstream or file trailer.
When I opened it I got this warning in chrome: "/deep/ combinator is deprecated. See https://www.chromestatus.com/features/6750456638341120 for more details."
If you remove the deprecated combinator it should open normally.

I'm creating a library for digitally signing a PDF document. During my quest I stumbled upon an other problem.
In Acrobat I'm getting the error:
Error during signature verification.
Adobe Acrobat error.
Expected a dict object.
I know it expects a dictionary object somewhere. But I have no idea where.
This problem shows up when I add the image to the AP of the signature.
For this I'm basing my implementation on the spec, and " Insert multiple digital approval signatures without invalidating the previous one "
Most of this seems to work correctly, but when the image is present it results in the error. The image is correctly visible.
Current working:
(This is a very short overview of the part where the error is, it might be slightly different, but hope this helps)
I update the signature annotation. Add link to object that contains normal appearance.

I think the problem happens somewhere in obj (21 0), but I'm not sure.
Here is a minimal file that can be used for testing.

Any help, or hints would be welcome.
(This post is a continuation of PDF Digital Signature has "Bad parameter" in Acrobat, but is about a different problem, same subject area.)
You're running into a bug of Adobe Acrobat here: If you display a XObject from inside your signature appearance stream, it expects that XObject to have a Resources entry. This may make sense in case of form XObjects but it doesn't for image XObjects like in your case.
A work around is to add an empty Resources dictionary to your image XObject.
I checked this by replacing the /BBox[1 0 0 1 0 0] in your image XObject (which is not needed there anyways) by /Resources<< >>.
When Adobe Acrobat creates its own signature appearances, it creates a hierarchy of form XObjects here with Resource dictionaries all over including those for the "layers". I assume Adobe Reader, seeing the Do operator attempts to collect information on such "layers", not expecting to immediately be confronted with an image XObject.
I am using the qpdf command to view the raw code (source code) of PDF files. Specifically I am using the command:
qpdf --qdf original.pdf unpacked.pdf
However a lot of PDF metadata is encrypted in this unpacked file and has a lot of unprintable ASCII charactars. I am interested in some data of pdf files which is actually encrypted. Assuming that I have the password for the pdf file (say pwd="passwd"), how can I get an output similar to the output of the qpdf command, but where data has been decrypted?
Edit:
An example file is attached in the link. Please check lines 1841 - 3258. Specifically, in the whole file I am not able to find the TransformParams dictionary, although I have added permissions. I believe it may be inside this encrypted text.

As already assumed in a comment to the question, the PDF file is not encrypted at all.
Please check lines 1841 - 3258
The lines 1841 - 3258 are part of a stream from line 1739 (OTTO...) to 3258 and contain an embedded OpenType font, compare the preceding stream dictionary

Specifically, in the whole file I am not able to find the TransformParams dictionary, although I have added permissions.
Well, the shared version of the file neither is encrypted (so no permissions have to be applied) nor is it digitally signed (so in particular there are no signature transform methods applied, so no TransformParams are there).
Maybe the information you search have been removed by uncompressing the PDF with qpdf, maybe they weren't there to start with. Thus, you probably should analyze the original file instead. Or you may want to explain your expectations more thoroughly, maybe there is an error in them.
I'm having problem with Incomplete or truncated stream while trying to pull data out of PDF interactive form. Could anyone help me with this please
PDFfile = open(fname, "rb")
pdfread = p2.PdfFileReader(PDFfile)
I'm having below error when i execute pdfread
Error -5 while decompressing data: incomplete or truncated stream
It mostly happens when you already opened pdf in different program or pdf is is corrupted. Try opening pdf with open()
The issue is the same as reported here.
I have taken this image and converted to this PDF using GraphicsMagick v1.3.26 (build on 2017-07-04):
gm convert itext_banner_InvalidPdfException.jpg itext_banner_InvalidPdfException.pdf
When I try to read it with iText v5.5.12 I get the following exception:
java -cp itextpdf-5.5.12.jar com.itextpdf.text.pdf.parser.PdfContentReaderTool itext_banner_InvalidPdfException.pdf
com.itextpdf.text.exceptions.InvalidPdfException: Rebuild failed: Dictionary key endstream is not a name. at file pointer 1197; Original message: Dictionary key endstream is not a name. at file pointer 1197

Questions:
What exactly is wrong with given PDF? It seems like there is an issue in GhostScript which is used indirectly by GraphicsMagick.
When I open it with iText RUPS v5.8.8, it does not print any warnings to Console tab. Does it mean it is valid from iText RUPS point of view?
Your PDF contains this broken object:
11 0 obj
<<
endstream
endobj
The opening << is closed by a endstream. This does not match.
If that object was meant to be a mere dictionary, it should have looked like this:
11 0 obj
<<
[a reasonable number of dictionary entries]
>>
endobj
If that object was meant to be a stream, it should have looked like this:
11 0 obj
<<
[a reasonable number of dictionary entries]
>>
stream
[stream data]
endstream
endobj
BTW, the object in question is not referenced from any other object in the PDF. If you open the PDF in a PdfReader in partial mode, therefore, the issue will be ignored.
I was wondering if there is any way to notify a user in adobe reader
that a pdf form has been submitted to the server? I am submitting a
normal http/html form to a php script no big deal, straight forward,
but there seems to be a big "black hole" in documentation, forums etc.
as to what happens when the form is submitted.
Isn't there a way to trigger a javascript alert after I have submitted
a form?? I dont't want to return another pdf that says "thank you",
that is a bit tacky. I am very new to pdf forms so I am guessing there
must be a way to return FDF to the original document that has some
javascript in it that is executed eg alert('thank you for your
feedback!')..
This should really be straight forward, I assumed Adobes much hyped
PDF technology was much more developer freindly and accessible..
Any ideas?? (Oh and please don't ask why I am using pdf forms and not the web, this is coming from "The Top", so as a developer I just have to do it..)
The server script which you are posting to must reply with this content type in the HTTP header:
'Content-Type: application/vnd.fdf'
eg. If you are using PHP:
header('Content-Type: application/vnd.fdf')
followed by the relevant bastardized-pdf-javascript-mutant-half-bread that will trigger the alert() dialog.

I hope you receive this message, as I wasted nearly 2 weeks of my life finding a solution...
Thanks for this! I too have been searching for a solution to this for hours! It was extremely frustrating. It seems like overkill to install the FDF Toolkit just to get a simple confirmation dialog box after the PDF has been submitted.
I eventually came up with the following through trial and error (it seems there is absolutely no documentation about this on the net):
%FDF-1.2
%âãÏÓ
1 0 obj
<<
/FDF
<<
/Status(Thank you. Your details have been submitted and someone will get in touch with regarding your application.)
>>
>>
endobj
trailer
<</Root 1 0 R>>
%%EOF
The above will present (or should present) a dialog box in Adobe Reader without showing the "Warning: JavaScript Window" warning.
Hope this ends up being useful to someone.
I wrangled with this for days, trying to figure out why when I sent the FDF using response.write, it just wouldn't display in Reader. I tried sending both hand-crafted FDF and installing the FDF toolkit to create the FDF response. I was able to create valid FDF, as I was able to open locally in Reader and have the pop-up display correctly but I couldn't get it to work for the life of me sending FDF from my ASP.NET page.
Then inspiration struck. In one of my attempts to send the FDF, I stored the FDF in a file and tried to use a streamreader to pump it into the response. After many unsuccessful attempts to use response.write, on a whim I tried response.redirect to the saved fdf file and it worked. I had previously added fdf as a registered MIME extension for my web site, with application/vnd.fdf as the MIME type. Now the user receives the pop-up after successful submission. The simple solution, in C#, looks like this:
Page.Response.Redirect("success.fdf");
I managed to happen upon the answer after 3 days of searching, adding a header for fdf file in the php script, adding '#FDF' to the end of the url in acrobat seems to have been the solution;
%FDF-1.2
