OpenOffice.org Password Cracker is what you make of it
What do you do if you forget the password to your OpenOffice.org files? The simplest solution is to download OOo Password Cracker, a macro for opening protected documents in any OpenOffice.org application. Using a brute force dictionary attack, OOo Password Cracker provides a slow but reliable method of document recovery. However, the macro requires some preparation if you want to use it effectively.
To start with, before you can use the spreadsheet that contains the OOo Password Cracker macro to open a password-protected file, you need to set up a directory that contains at least one dictionary. The dictionary is a plain text file, with one possible password per line. The macro does not recognize commented lines, but you can use them to annotate the dictionary anyway. Although OOo Password Cracker will read them as possible passwords, they will not significantly slow down the macro and may be convenient for you.
Once you have a dictionary set up, you can open the spreadsheet that contains the macro.
