the script is erasing the input PDF's
please look into it.

With pdf.py, on each PDF I've tried so far, I get errors like below. Tips how to solve this?

For example

$ python pdf.py bezuidenhout.pdf vakantieoverzicht.pdf 
error: expected 'obj' keyword (22 222 ?)
warning: trying to repair broken xref
warning: repairing PDF document

and (with the provided exampled PDF's):

sander@sammie:~/git/pocs/collisions/scripts$ python pdf.py ../examples/poeMD5_A.pdf ../examples/poeMD5_B.pdf 
warning: PDF stream Length incorrect
warning: PDF stream Length incorrect

Installed mutool version is 1.14, so uptodate:

$ apt list --installed | grep mupdf
mupdf-tools/cosmic,now 1.14.0-0build1+ubuntu18.10 amd64 [installed]
mupdf/cosmic,now 1.14.0-0build1+ubuntu18.10 amd64 [installed]

I am using Pycharm. I downloaded the entire package, and I have a project ready to go. I also downloaded a png and dcm from Tiny. I opened the console and typed "mitra.py pdf.pgn dicom.dcm" and it seemed to run, but I don't see the new polyglot anywhere so I'm not sure. Your repository may be incredibly useful in polyglot detection experiments. Please help, thank you.

Hey, when I try to implement the 'angencryption' project with pdf, everything goes smooth except that the payload apk couldn't be installed, the error being there was a problem parsing the package.

I have implemented the same version of the wrapping apk as for the png and jpg formats. It works well with PNG and JPG. Should I assume that the error is indeed in this part i.e. in interpreting and decrypting the pdf?

Secondly, Can this PDF/APK format polyglot work on latest Android versions, may be at least Lollipop.
Kindly help.
I shall be obliged.
Regards

Please consider adding a licence file /details. (Even if just public domain).
I'd like to include some of your png images in a corpus for compression testing.
Cheers.

Is it useful to have a minimal .dll?

FYI.

I have software to generate a simple PE executable that works fine in Windows XP/Vista/7. However, it doesn't work in Windows 8 or 10. The original version left out the data directories.

I updated the software to include 16 data directory entries. This made the executable run in Windows 8 and 10.
