Password cracker

This project was made in a week and had learning goals more than final usability, prettiness or quality in general.

Although this can be used for educational purposes, you should not rely on it to provide you with extremely accurate information, or estimation of your password's strength.

More info

To compile the go part of the program, a Makefile is provided in crack_passwd: just run 'make' in that directory. (See dependencies first)

To launch the program, just (double) click on the run.sh file.

Features:

• Efficient use of the ressources. This program run on your CPU and use all but one thread.
• Scales up to 26/52/62 threads in bruteforce mode (depending on the length of the alphabet), and up to 100 threads in dictionnary mode.
• GUI fully functional
• Crack password from aA-zZ,0-9, bruteforce limited to 16 characters.

Dependencies: Openssl (to create new users) Go to re-compile binaries A gnu-style make to use the (short) makefile. Two go libraries to compute hashes. Those can be pulled from the go repos anytime and i have no control over it. Such a problem would appear at compile time.

Troubleshooting:

• Program does not launch, nothing is happening/ just opening the run.sh as text: Check the permissions of run.sh, if it not executable, you should open a terminal, navigate to the directory containing run.sh and type "chmod +x run.sh"

• Program launch but some windows are blank: Are you sure to have selected all the fields? (eg: alphabet for bruteforce). You should read what's onscreen before clicking Ok

• Program is slow after the previous one crashed. You should "kill background process" by clicking on the button. The previous program must still be running. Then start over.

• Other: make sure to run the program as a normal user, with a ~ home directory and access to it.

Who can be intersted by this project? Not many people, hmm. This is not a state-of-the-art solution to hash cracking (better tools exist to do that).

Some avantages of this project are:

• reasonably fast operation
• educative vision: short text messages explaining the how and why
• works with real password files and the fake ones the program can generate

WIP:

• proper thread communication and result returning
