It will only ever work this way, not the other. For reference, old .doc where simply flagged as "password protected", which of course got us OpenOffice/LibreOffice simply opening them without warning ;) On the other hand, open password for .odt (and other open document formats) always implied some form of encryption. Granted, previous versions might have used what is now weak encryption, but still it is not something that can be opened easily without password, especially if the file is manipulated on a regular basis, as recent versions of LibreOffice might simply have overwritten the old encryption with something more up to date. I'm afraid that beside brute-force (using a dedicated program) or an unencrypted backup there is no much hope. -- 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
