Howto: Crack Rar, 7z, and zip files with RarCrack in Ubuntu Linux

Ever run into the problem where you created a password protected zip/rar file and you forgot the password or accidentally deleted it? Or just dont know the password at all? Well I have come across a nice solution for cracking zip/rar files. Its called rarcrack, If you forget your password for compressed archive (rar, 7z, zip), this program is the solution.
This program uses bruteforce algorithm to find correct password. You can specify which characters will be used in password generations.

Download RarCrack
wget http://superb-east.dl.sourceforge.net/sourceforge/rarcrack/rarcrack-0.2.tar.bz2
Install RarCrack
tar xvjf rarcrack-0.2.tar.bz2
cd rarcrack-0.2
make ; sudo make install
Using RarCrack:

rarcrack your_encrypted_archive.ext [--threads thread_num] [--type rar|zip|7z]

Everything in [] are optional, rarcrack default crack two threads and autodetect the archive type. If the detection wrong you can specify the correct file type with the type parameter. RarCrack currently crack maximum in 12 threads.

After the cracking started RarCrack will print the current status of cracking and save it’s to a status file. If you want more specific password character set, you need to run RarCrack to create the XML status file (3 sec).

There will be a sample XML file, and you see there is a character set. If you want, you can modify this file and when you start RarCrack again the program will be use new variables.
Warning: Take care when you changing this file, make sure the current password don’t have characters outside the abc[character set]!

Know of any other rar/zip/7z cracking tools worth mentioning?

    hello salam kenal. aku baru nech di linux sekarang aku menggunakan ubuntu muslim edition 8.10. aku nginstall rarcrack sesuai dengan petunjuk. yang ada di blog ini juga aku ikuti petunjuk di reedme.html yang terkompresi bareng ama rarcrack-0.2.tar.gz. tapi sampe hari ini aku belum bisa membongkar pasword yang formatnya *.zip dan *.7zip. tapi kalo yang *.rar udah mau. aku test dengan mengkreck “test.rar”, “test.zip”, test.7zip” tolongin aku dunk.
    kalo ngekreck yang *.zip ama *.7zip ada pesan “segmentation fault”. padahal katanya kan suport ama *.zip dan *.7zip. tolongin dunk plese. kirim ke mail ku ya tanjung.amat@yahoo.co.id. tanksssssssssss

  3. It does not work. XML file gives last character output. No way to determine the number of thread (If that means to be the number of character used as password)
    Every time it is run it gives new password. No way to determine if it is working at all. Seems a sham.

    rarcrack is a joke.

    The developer pooched the printf function such that the only way it runs is with the “–type rar” switch (it cannot detect normally), and the password generated is NEVER correct. I created an RAR with a password to see. It NEVER found the password, but dutifully spat out a password and called it good.

    That is a two hour span I’ll never get back.
