Re: [libreoffice-users] Re: how to crack a PW in LO?

Hi :)
This is pitiful.  OpenSource sometimes has a reputation of being where reformed hackers go when 
they grow up or when they want more kudos.  Maybe the devs list might have ideas?  It's just 1 
password!  It can't be this tough!  Maybe that reputation is just more FUD after all!  

Maybe try with Caps Lock off and then again with Caps Lock
on.  For some reason it recently seemed to make a difference if Num
Lock was on, even when it was on i would have to switch it off and then
on again.  I thought it was just me but it's happened to me on a few
different machines now and on all 3 OSes i commonly use.  Hmm, it could still be me.

Regards from
Tom :)

I used the following:
http://www.crackpdf.com/
but not the Pro version which allows to make brute force attack, but then, they warn you that it 
will take _a_long_time_ !!!
To remove simple protections, it was really fast, but they unlock the file without retrieving the 
password (or at least they don't display it)
