Hello all,
I'm trying to read attached password-protected (password is 'password')
document with following piece of code:
-----
PdfMemDocument document;
try {
document.Load(pdfFile);
} catch (PdfError& e) {
if ((e.GetError() == ePdfError_InvalidPassword) && pcarPassword)
document.SetPassword(pcarPassword);
else {
raiseError(e);
return;
}
}
-----
But it raise an error when calling SetPassword() with following stack:
PdfError::AddToCallstack(const char * pszFile, int line, const char *
pszInformation) Line 522 C++
PdfError::SetError(const PoDoFo::EPdfError & eCode, const char *
pszFile, int line, const char * pszInformation) Line 515 C++
PdfError::PdfError(const PoDoFo::EPdfError & eCode, const char *
pszFile, int line, const char * pszInformation) Line 114 C++
PdfAESStream::Decrypt(unsigned char * pBuffer, int lLen, int *
pTotalLeft) Line 411 + 0x2b bytes C++
PdfAESInputStream::Read(char * pBuffer, int lLen, int * pTotalLeft)

PdfStream::SetRawData(PoDoFo::PdfInputStream * pStream, int lLen) Line

C++
PdfParser::ReadObjectsInternal() Line 1233 C++
PdfParser::SetPassword(const
std::basic_string<char,std::char_traits<char>,std::allocator<char> > &
sPassword) Line 1277 C++
PdfMemDocument::SetPassword(const
std::basic_string<char,std::char_traits<char>,std::allocator<char> > &
sPassword) Line 425 C++
The call returning an error in PdfEncrypt.cpp is at line 400:
status = EVP_DecryptUpdate( aes, pBuffer, &lOutLen, pBuffer +
AES_IV_LENGTH, lLen - AES_IV_LENGTH );
Thank you in advance for your help.
