SYNOPSISbruteforce-luks [options] <path to LUKS volume>
DESCRIPTIONThe purpose of this program is to try to find the password of a LUKS encrypted volume.
It can be used in two ways:
• brute force attack: try all the possible passwords given a character set. 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).
• dictionary attack: try all the passwords in a file.
The program can use several threads (the number of threads can be specified with the -t command line option).
Sending a USR1 signal to a running bruteforce-luks process makes it print progress info to standard error and continue.
- -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.
- 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
EXAMPLESTry 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/sdb1Try 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/sda2Try 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/sdc3Try 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/sdd1Instead of passing a block device to the program, you can copy the beginning of the LUKS volume to a file and pass this file to the program:
sudo dd if=/dev/sda1 of=/tmp/luks-header bs=1M count=10 bruteforce-luks -t 4 -l 5 -m 5 /tmp/luks-headerPrint progress info:
pkill -USR1 -f bruteforce-luks
