That's the point of encryption, since a bruteforce attack is always possible with every cryptosystems :-) However, you're right; for most people this option is more like a trap if it is not part of a greater document management system that does take care of the details like password, keys, and allow for some kind of recovery. Maybe there should be a warning box that explicitely state that the document will be lost if the password is lost. -- To unsubscribe e-mail to: [email protected] Problems? http://www.libreoffice.org/get-help/mailing-lists/how-to-unsubscribe/ Posting guidelines + more: http://wiki.documentfoundation.org/Netiquette List archive: http://listarchives.libreoffice.org/global/users/ All messages sent to this list will be publicly archived and cannot be deleted
