Greetings
I've downloaded the latest PoDoFo (version 0.9.3) and I'm trying to load an
encrypted PDF, but I can't seem to get it to work.
Here's what I'm doing:
try {
PdfMemDocument *doc;
doc = new PdfMemDocument();
try {
doc->Load("/Users/ismael/Downloads/password_Password01.pdf");
} catch (PdfError &error) {
if (error.GetError() == ePdfError_InvalidPassword) {
doc->SetPassword("Password01");
} else {
return false;
}
}
doc->Write("/Users/ismael/Downloads/output_Password01.pdf");
} catch (PdfError &error) {
return false;
}
doc->Load(...); throws an InvalidPassword error, as expected, but when I do
doc->SetPassword(...); it throws an InternalLogic error. Debugging I found
that the error comes from PdfEncrypt.cpp.Decrypt(...) here:
status = EVP_DecryptFinal_ex( aes, pBuffer + lOutLen, &lStepOutLen );
if( status != 1 )
PODOFO_RAISE_ERROR_INFO( ePdfError_InternalLogic, "Error
AES-decryption data padding" );
EVP_DecryptFinal_ex returns 0 and then the error is raised. This is
happening to me with three different PDF files that were generated in
different ways. They work normally on any viewer application, and I'm at a
loss as to why this is not working.
Sincerely,
Ismael
