Hi,

I Forger My password of the Libreoffice file . 
Who can tell me how to deal with it ?


Other than a brute force attack, with a massive dictionary of potential
strings and something like "john the ripper" or some other such
software, there is no known way. It is possible, if you have a few
thousand years in front of you, but by then, it is generally of little help.

See here for an explanation of the technology used and why that makes it
so difficult for mere mortals :
