RARCRACK - How to crack RAR archieve password in Ubuntu Intrepid

, , , ,

It happen last 2 year, when bought this laptop and move all my files from windows pc. Some of my freinds giving me a suggestion to pack things up and archeive in .rar format.

At that time, I'm thinking that I should encrypt my rar files with password. So, I did it. But when the laptop arrive I'm to to busy to start install a new version of windows OS, the so-called 'Windows Xp Sp3'. And then, I moved to Ubuntu.

Everything was ok, until one day when my wife asking for our beloved son's picture. Then I start to unrar the encrypted files and failed to remember the password.

Now, I will introduce you with RARCRACK (maybe some of you already know about this package). You can get this file from sourceforge.net But last time I have compiled it in deb package. You can get it rarcrack_0.2-1_i386.deb here.

Both package need dependency, so open your terminal and type in this code
sudo apt-get install libxml2-dev
Then installed the package.

The usage is simple and straight-forward. Lets say, I have a rar file in /home/azwar/picture.rar. Open your terminal and type in this code
rarcrack /home/azwar/picture.rar
the result should be like this
azwar@linux-intrepid:~$ rarcrack /home/azwar/picture.rar

Probing: '9X' [21 pwds/sec]
Probing: 'b0' [21 pwds/sec]
and for more option just type in
rarcrack --help
It can also be use with zip and 7z format (I never try other than rar)

FYI, the file name should not have spacing e.g

my picture.rar

change the file name to

mypicture.rar

. if not, you will get an error masssage.

you don't have a right permissions!

well I should say like this,

1. make sure the installed package together with all dependencies.

2. check the spelling for the said file you crack.

3. check the file permission. you need to have the ability to read/write the said file.

try the 3 above solution, I wish you luck.:smile:

INFO: detected file type: rar
INFO: cracking /home/***/***/***.rar, status file: /***/***/***/***.rar.xml
GOOD: password cracked: '1'
GOOD: password cracked: '0'

I fear it didn't work out. the xml file shows the follwings:




0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ

c

I got a seg fault when typing it without params. If you get this then try:
rarcrack your_encrypted_archive.ext [--threads thread_num] [--type rar|zip|7z]
