Hi,

Hi,
I believe it's just a bug. Could you share your change in a form of a
patch, please? (If you are not having a svn checkout, then have a file
before your change, then after and generate the patch using diff
command:
   $ diff -up file.before file.after >change.patch
There are available windows executables for the diff too. The "-up"
parameter tells the diff to create a unified diff and reference the
method it is diffing in (usually in C/C++ code it's that method, even
not always).
Thanks and bye,
Milan

Re: [Podofo-users] Problem with loading password protected PDF

[F. E.]

Hello again,

Thanks for the last answer.

I tried running the encrypt.cpp, but encountered compile, link and runtime
errors (bad alloc). With the help of a collegue we started from scratch and
rebuilt podofo and all dependent libraries. Now it's working, my example
code as well as encrypt.cpp.
When using CMake to generate the vs project files, however, we encountered
an minor issue with the generation. Although we specified everything needed
for OpenSSL (-DCMAKE_INCLUDE_PATH / -DCMAKE_LIBRARY_PATH /
-DLIBCRYPTO_LIBRARY_NAMES_DEBUG / -DLIBCRYPTO_LIBRARY_NAMES_RELEASE) and
OpenSSL got enabled in podofo_config.h, the include directories were not
added to the projects. That resulted in a compile error (missing header in
PDFEncrypt.cpp). We checked CMakeLists.txt and found that there was no
INCLUDE_DIRECTORIES call for the OpenSSl include dir (line 322ff.), unlike
with other libraries like libjpeg. We added that call and it generated the
project files correctly. But we're not sure if that solution is correct.

Is there a reason the INCLUDE_DIRECTORIES are not set for OpenSSL or is it
just a bug?

Best regards,
F.E.

Hi,
could you try to compile and run the encrypt.cpp attached at
https://sourceforge.net/p/podofo/mailman/message/34065834/
please? That works for me fine. It uses the same method (way of loading
the files it created) as you outlined here. There might also be related
whether you compiled with the openssl and the encryption/decryption
method the PDF file is encrypted supported.

With respect of PDF file sharing, if you can make a very simple and
small example PDF which fails for you, with no confidential data, then
there's no problem to send it to this mailing list, I believe.
Bye,
zyx

[Podofo-users] Problem with loading password protected PDF

[Max Müller]

Hello,


when playing around with Podofo I stumbled upon an issue that I'm not able
to load password protected PDFs. I already saw some earlier issues from
other people (e.g.
https://www.mail-archive.com/podofo-users@lists.sourceforge.net/msg01145.html),
but that doesn't help me.

My procedure:
I create the PDfMemDocument Object, call Load on it, catch the
InvalidPassword error and provide the correct one by calling SetPassword.
But that results in the InvalidPassword error as well. I'm absolutely sure
my password is correct, since I can view the file with it in a PDF Viewer.
Has someone a hint what I'm doing wrong?

Code:
void TestPDFLoad( const std::string& pdfFile, const std::string& pdfPwd )
{
std::shared_ptr< PdfMemDocument > pDocument ( new PdfMemDocument() );

try
{
pDocument->Load( pdfFile.c_str() ); return;
}
catch ( PdfError error )
{
EPdfError errorCode = error.GetError();
if ( ePdfError_InvalidPassword != error.GetError() )
{
error.PrintErrorMsg(); return;
}
}

// Error was "InvalidPassword", so provide one
try
{
pDocument->SetPassword( pdfPwd ); return;
}
catch ( PdfError error )
{
error.PrintErrorMsg();
}
}

Output:
PoDoFo encounter an error. Error: 31 ePdfError_InvalidPassword
Error Description: The password used to open the PDF file was
invalid.
Callstack:
#0 Error Source:
E:\SVN\research\PDFCrypt\Libraries\_podofo-0.9.3\src\ba
se\PdfParser.cpp:1148
Information: Authentication with user specified password
failed.

I can provide the file and password, but I guess I shouldn't append it to
the mail, should I?

Best regards,
F.E.
