CrackTC

~About~

CrackTC is a very simple little Java-app which can be used to find the correct password for a TrueCrypt volume. It only works with Linux. 

~Using It~

*If you don't have Linux, download Damn Small Linux or Ubuntu, and install it within VirtualBox then install TrueCrypt inside of the Linux Distro*


TrueCrypt tries to invoke "truecrypt -p *password* *truecrypt-file*" and TrueCrypt in Windows it does not work like that.
 
I recommend making a temporary TrueCrypt file and a temporary password file just to try CrackTC out and get a hang of how it works, so you're sure you're doing it right when trying to find the correct password for your "real" volume. See the examples folder for this.

Example: java CrackTC myVolume.tc passwords.txt

passwords.txt should be like:

password1
password2
password3
password4
password5
etc...

Please note that the TrueCrypt volume must be dismounted!

Usually that is:

truecrypt -d /dev/mapper/truecrypt0 

~Generate Passwords~

To generate passwords I used Password Generator Professional 2007. 
 
http://www.kristanixsoftware.com/passwordgenerator/

It was great for me since this program has a "masking mode" (i.e. you can say that, for example, the first letter must be a selection of some specific letters, and that the second only can be a number, and so on. So if you know stuff like that, you can minimize the combinations considerably).

~Notes~

Note that the app is incredibly slow. On an Intel Core 2 Duo @ 2880MHz, it tries about 4.1 passwords per second. On an AMD XP 2800+, 2.5 passwords / second. 
So if you've got billions of different possible combinations it will take a LONG time. 

When I made this program, the password I had lost wasn't entirely lost. I didn't know exactly how it was, just approximately. So from that knowledge, I could generate about 40,000 possible combinations, and CrackTC found my password within an hour (though it could have taken longer).

This torrent is only for CrackTC and does not include a password generator, TrueCrypt, VirtualBox, or any Linux Distros.
