I m maybe a little bit late but I m currently trying to develop a program which can brute force a password protected zip archive  First I tried all commands I found in the internet to extract it through cmd    But it never worked    Every time I tried it  the cmd output said  that the key was wrong but it was right  I think they just disenabled this function in a current version   What I ve done to Solve the problem was to download an older 7zip version 4    and to use this for extracting  through cmd   This is the command    C  Program Files  86  old7-zip 7z exe  x -pKey  C  YOURE ZIP PATH    The first value  C  Program Files  86  old7-zip 7z exe   has to be the path where you have installed the old 7zip to  The x is for extract and the -p For you re password  Make sure you put your password without any spaces behind  the -p  The last value is your zip archive to extract  The destination where the zip is extracted to will be the current path of cmd  You can change it with   cd YOURE PATH   Now I let execute this command through java with my password trys  Then I check the error output stream of cmd and if it is null-  then the password is right

General Syntax   7z a archive name target parameters   Check your 7-Zip dir  Depending on the release you have  7z may be replaced with 7za in the syntax   Parameters     -p encrypt and prompt for PW   -pPUT PASSWORD HERE  this replaces -p  if you want to preset the PW with no prompt   -mhe on to hide file structure  otherwise file structure and names will be visible by default    Eg  This will prompt for a PW and hide file structures   7z a archive name target -p -mhe on   Eg  No prompt  visible file structure   7z a archive name target -pPUT PASSWORD HERE   And so on  If you leave target blank  7z will assume   in current directory and it will recurs directories by default
