Anything else (such as the ones Leonard listed)... iText takes one look and says "not Standard, can't help ya". Sounds like the exception it throws could be a little more informative. It's possible to implement other security handlers within iText, but you'd have to know how they actually work to pull that off. Adobe isn't telling. PS: You can create an "opaque" security handler by simply renaming the standard one... maybe throw in an XOR somewhere. Then only people with your special code (not hard to write a security handler plugin for Acrobat, IIRC there was a sample in the SDK), can open your files. --Mark Storer Senior Software Engineer Cardiff.com #include <disclaimer> typedef std::disclaimer<Cardiff> Discard; ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/ _______________________________________________ iText-questions mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/itext-questions Do you like iText?
