NAME

       bruteforce-luks - try to find the password of a LUKS volume

SYNOPSIS

       bruteforce-luks [options] <path to LUKS volume>

DESCRIPTION

       The  program  tries  to  decrypt  at least one of the key slots by trying all the possible
       passwords. It is especially useful if you know something  about  the  password  (i.e.  you
       forgot  a  part of your password but still remember most of it). Finding the password of a
       volume without knowing anything about it would take way too much time (unless the password
       is really short and/or weak).

       There are command line options to specify:

              • the minimum password length to try

              • the maximum password length to try

              • the beginning of the password

              • the end of the password

              • the character set to use (among the characters of the current locale)

OPTIONS

       -b <string>
              Beginning of the password.
              Default: ""

       -e <string>
              End of the password.
              Default: ""

       -f <file>
              Read the passwords from a file instead of generating them.

       -h
              Show help and quit.

       -l <length>
              Minimum password length (beginning and end included).
              Default: 1

       -m <length>
              Maximum password length (beginning and end included).
              Default: 8

       -s <string>
              Password character set.
              Default: "0123456789ABCDEFGHIJKLMNOPQRSTU
                        VWXYZabcdefghijklmnopqrstuvwxyz"

       -t <n>
              Number of threads to use.
              Default: 1

       Sending a USR1 signal to a running bruteforce-luks process
       makes it print progress info to standard error and continue.

EXAMPLES

       Try to find the password of a LUKS encrypted volume using 4 threads, trying only passwords
       with 5 characters:

           bruteforce-luks -t 4 -l 5 -m 5 /dev/sdb1

       Try to find the password of a LUKS encrypted volume using 8 threads, trying only passwords
       with 5 to 10 characters beginning with "W4l" and ending with "z":

           bruteforce-luks -t 8 -l 5 -m 10 -b "W4l" -e "z" /dev/sda2

       Try to find the password of a LUKS encrypted volume using 8 threads, trying only passwords
       with 10 characters using the character set "P情8ŭ":

           bruteforce-luks -t 8 -l 10 -m 10 -s "P情8ŭ" /dev/sdc3

       Try to find the password of a LUKS encrypted volume using 6 threads, trying the  passwords
       contained in a dictionary file:

           bruteforce-luks -t 6 -f dictionary.txt /dev/sdd1

       Print progress info:

           pkill -USR1 -f bruteforce-luks
