If you're motivated, here's a piece of code that attempt a very poor bruteforce, but have all the pieces needed to make a real brute-force app. (disclaimer: this is like the monster from frankenstein, I cut & pasted code from all around the web, as I have zero knowledge about Java bindings for UNO). http://pastebin.com/cQJnA8F6 It will try to open a file located at e:\test.odt, and use passwords from "tota", "totb", "totc"... to "tott" (more or less). Still, it is probably very easy to change it so that it use proper, parametrized passwords guess, and have some form of UI. If no one else look into this, I might give it a go. (for this stub to work, you need a running instance of libreoffice started with the command line "$ soffice.exe -accept=socket,host=0,port=2002;urp;") It is 100% possible to integrate this better, in a way that would automatically launch an invisible instance of LibreOffice. In fact the first SDK sample does this, but as I run a 64-bit version of Java, I had to go this way. YMMV. -- Cley Faye http://cleyfaye.net -- To unsubscribe e-mail to: users+unsubscr...@global.libreoffice.org 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
