Process PDF protected by password fails.

Post by ShadowStar » 2017-03-08T03:59:07-07:00

I have a problem managing pdf with password.
The command convert with -authenticate <password> seems doesn't work.

I am using a computer with the following configuration:
SO:Windows 10 home edition 64 bit
Imagemagick Version:

ImageMagick 7.0.5-1 Q16 x64 2017-03-04 http://www.imagemagick.org
Copyright: Copyright (C) 1999-2015 ImageMagick Studio LLC

Features: Cipher DPC Modules OpenMP
Delegates (built-in): bzlib cairo flif freetype jng jp2 jpeg lcms lqr openexr pangocairo png ps rsvg tiff webp xml zlib

I tried to create jpeg and gif from a protected pdf.
I tried to use the following comand:

convert -authenticate 5f9bd2f2f465b3535b48c664e6c68d7b 1_8d0b4fd2f4.pdf test.jpg

and I received the following error message

convert: PDFDelegateFailed `[ghostscript library 9.20] -q -dQUIET -dSAFER -dBATCH -dNOPAUSE -dNOPROMPT -dMaxBitmap=500000000 -dAlignToPixels=0 -dGridFitTT=2 "-sDEVICE=pamcmyk32" -dTextAlphaBits=4 -dGraphicsAlphaBits=4 "-r72x72" -dUseCIEColor "-sOutputFile=C:/Users/SQUATT~1/AppData/Local/Temp/magick-4928zJv9DtYHVMAg%d" "-fC:/Users/SQUATT~1/AppData/Local/Temp/magick-4928DDtDU4qsbyzU" "-fC:/Users/SQUATT~1/AppData/Local/Temp/magick-4928gE2ciUCx7dDo"': **** This file requires a password for access.

convert: no images defined `test.jpg' @ error/convert.c/ConvertImageCommand/3254.



To verify it it is a Ghostscript problem I tried to create a jpeg file using the following command:

gs -q -dQUIET -dSAFER -dBATCH -dNOPAUSE -dNOPROMPT -sOutputFile=test.jpg -sPDFPassword=5f9bd2f2f465b3535b48c664e6c68d7b 1_8d0b4fd2f4.pdf

Ghostscript created the image without any error.


Investigating more, it seems that imagemagick doesn't set the password parameter when invoking the delegate during the conversion.
I verified it, I tried to change temporarily the file delegate.xml inside my imagemagick folder installation D:\Program Files\ImageMagick-7.0.5-Q16 adding the password parameter with the password of pdf I need to create the jpeg:

<delegate decode="ps:cmyk" stealth="True" command="&quot;@PSDelegate@&quot; -q -dQUIET -sPDFPassword=5f9bd2f2f465b3535b48c664e6c68d7b -dSAFER -dBATCH -dNOPAUSE -dNOPROMPT -dMaxBitmap=500000000 -dAlignToPixels=0 -dGridFitTT=2 &quot;-sDEVICE=pamcmyk32&quot; -dTextAlphaBits=%u -dGraphicsAlphaBits=%u &quot;-r%s&quot; %s &quot;-sOutputFile=%s&quot; &quot;-f%s&quot; &quot;-f%s&quot;"/>

and than to execute the command
convert -authenticate 5f9bd2f2f465b3535b48c664e6c68d7b 1_8d0b4fd2f4.pdf test.jpg

again and it works.

I already used the -authenticate option with many versions of linux (Debian, Centos) and windows (Windows 7, 8, 8.1) but this is the first time I have this kind of problem.
Thanks in advance.

Easy fix. Can you post a URL to a password protected PDF and its associated password. We will dowload the PDF and use it to verify our patch. Thanks.

Thanks for the problem report. We can reproduce it and will have a patch to fix it in GIT master branch @ https://github.com/ImageMagick/ImageMagick later today. The patch will be available in the beta releases of ImageMagick @ http://www.imagemagick.org/download/beta/ by sometime tomorrow.

I have dowloaded the last version of imagemagick for Windows 10 (7.0.5-2) where is reported fixed the problem. I tried to use convert with the test file you sent me, but the conversion still fails.

This is the new version of Imagemagick I used:

I tried the following command: convert -authenticate 5f9bd2f2f465b3535b48c664e6c68d7b 1_8d0b4fd2f4.pdf test.jpg

and I got the following message:

Apparently the patch did not make it from our development area to the git repository. We'll have a fix in the next point release within the next few days.

Did you add `-authenticate` with the password and are you using the latest version?

Would you point me to that patch?
Which version of ImageMagick has solved this bug?

(I have just filed https://bugzilla.redhat.com/show_bug.cgi?id=1520117 to track this issue in Fedora's ImageMagick-6.9.9.22-1.fc27.x86_64 )
