Hi, I did some testing and the problem is that PdfEncryptAESV3::Decrypt uses m_encryptionKey which contains all zeros, but calling if (ok) GenerateEncryptionKey(""); in PdfEncryptAESV3::Authenticate() is not enough (even it generates the same key on a document load), because the decrypt as such fails. I guess it's due to initialization vectors ('iv' in PdfEncryptAESBase::AES()), though I'm not able to properly decrypt the data directly in PdfEncryptAESV3::Encrypt(). I admit I have no idea how AES should work in PDF (and in general too). pzent, could you follow-up on your commit [1], please? Or maybe Dominik?
