Ok, the problem is, i can encrypt the PDF correctly, but i cannot open the PDF
with the password „owner“:
encrypt = PdfEncrypt::CreatePdfEncrypt("", "owner", 0,
PdfEncrypt::ePdfEncryptAlgorithm_AESV2, PdfEncrypt::ePdfKeyLength_128);
I compile podofo with these options:
/* Libraries */
#define PODOFO_HAVE_JPEG_LIB
#define PODOFO_HAVE_PNG_LIB
#define PODOFO_HAVE_TIFF_LIB
#define PODOFO_HAVE_OPENSSL
#define PODOFO_HAVE_OPENSSL_1_1
#define PODOFO_HAVE_OPENSSL_NO_RC4
