Hi :)
The trick is to try to remember what you might have been thinking about at the 
time.  If that's even possible for anyone!

There is no password cracking functionality or Extension for LO it's just the 
inept way MS fails to implement security.  Just double-click on an xls or open 
LO and drop the xls into it or open LO and choose
File - Open
to navigate to and open the xls.  File opens.

My company's finance department asked me to add something to one of their 
spreadsheets but 'forgot' to tell me the password.  One of them rushed down to 
give me the password but was somewhat mortified to find i had already made the 
change without having the slightest idea that there even was a password.  There 
was a very cofusing conversation where neither of us had a clue what the other 
was talking about until i figured it out.

The company still uses Excel and still attempts to 'protect' those spreadsheets 
with passwords that don't work.  Occasionally people give me other files they 
want cracked which gives me a morale dilemma each time.  Usually i just give a 
really half-hearted non-effort and then fob them off.

Tom :)

LO files can be protected with PWs when doing "save as".
Fighting currently with an xls file and its lost PW, I wonder how LO files can 
be cracked? Can the
MS related PW remover be used for LO as well?
Thanks in advance for comments.


xls does not encript your document. The only thing that gets encrypted
is the password. Any old version of OpenOffice.org opens a password
"protected" xls ignoring the password.
Thanks for the information. It seems that my version of LO 3.5.6.2 is too young 
to ignore the PW of
an xls file.

However, my question was how to open an LO file if the PW get forgotten (not 
and MS file)?
Hints are welcome for the future.



Thanks to all of you providing me with lots of hints on not to forget passwords or prepare in advance for it. The SW I am using to crack an xls-file runs already for more than 60 h in the background. It's a nothing to loose only to win job. 6 or 8 digits alphanumeric no special characters is the PW used.

Thereafter I will make a test cracking an LO file.

The only thing which makes me wonder is that there are PW removing SW commercially availabe which run demos and claim within 10 - 30 sec they could remove the PW but open the xls file only when I purchase a full license.

Does someone has experience with such a SW?
