Re: [dev] password
Hi Gregory, I'm sorry, but the algorithm, that OOo uses for password encryption is secure. You can't recover it. What you could try - if you have a simple password - is a so called Brute Force attack, where you try all possible iterations of your password. But as I said, only if you used a simple password.

I looked around and found something called a stamp number from roaming if that means anything. 5C8C378AD1397C685A285738E8C56329 Not sure what you mean with roaming and stamp number. I tried seeing if it was ASCII, it's not. From what I remember it has the word Clarity in it but from there I'm stumped. When I look at the code on some program, can't remember that one either, there's a lot of PK on the beginning and end like they are the start of words. OpenDokument are Zip files that contain xml files. When saving with a password, not the zip container is protected, but the individual xml files. The algorithm used is blowfish, which is considered secure. No attacks apart from brute force known. Even when you use the same password to save two otherwise identical documents, the result will be different, as the actual key is initialized with a randomly generated initialization sequence (that is stored in the META-INF/manifest.xml file) - so trying to guess the password by looking at a different document with a similar (but known) password won't work either (won't work when the password was the same either). Only way to recover the document is trying every possible password (thus performing a brute-force attack). Success rate then depends on how much you still know from the password, how many different passwords have to be tried. ciao Christian - To unsubscribe, e-mail: dev-unsubscr...@openoffice.org For additional commands, e-mail: dev-h...@openoffice.org

Re: [dev] Password protect extension
Hi all, I really do not see the scenario: - if the extension is installed in shared mode, you have to be admin to remove the extension - if the extension is installed in the user layer and you'd need a password do disable or remove it, you could always just remove the complete user installation to get rid of the extension.

Re: [dev] Password Recovery
Hi Manish Try this site. http://www.gtopala.com/ and down load the SIW utility. I have this neat little utility and it will display all hidden passwords used with windows OS. It may work for OO docs too. Good luck Gail Anthony Chilco wrote: Hi Manish, This is probably not the best list to post such a question. [EMAIL PROTECTED] might be a better place.
