Hi,
you can find one simple test code here:
http://sourceforge.net/p/podofo/mailman/message/32079121/
Basically:
PdfEncrypt *encrypt;
encrypt = PdfEncrypt::CreatePdfEncrypt("user", "owner", 0, algo,
keyLength);
PODOFO_RAISE_LOGIC_IF (!encrypt, "!encrypt");
PdfMemDocument *memDocument = new PdfMemDocument();
PODOFO_RAISE_LOGIC_IF (!memDocument, "!memDocument");
memDocument->SetEncrypted(*encrypt);
delete encrypt;
where "user" is a user password (use an empty string for no user
password, thus everyone can open the document) and "owner" is an owner
password.
Bye,
zyx
