Crack 7zip Password Protected Archive [Hack]

7zip is the most recommended way of compressing the files into an archive. It is an opensource tool which allows quick compression and extraction of 7zip, Gzip, Zip, Rar, and other archives. Most users tend to lock the 7zip file with a password but hackers can still extract the archive by bypassing the password. Let me explain how.

7z Cracker is an opensource cracking tool which can extract any password protected 7zip file. It is developed for the purpose of helping users recover their files if they have forgotten the password.

The process is pretty straight forward, once you extract the 7z Cracker, grab the 7zip command line tool called 7za.exe(link given at the bottom of this post) and put it inside the same directory where 7zCracker is residing. Also move the password protected 7zip file (that you want to crack/extract) into the same directory. Now start 7zCracker.exe and enter the archive name along with the extension as shown in the screenshot below.

Once you hit Enter, the 7zip archive will be extracted and you will find the content inside the est folder.

Editor’s Important Note: While adding files to 7zip archive, just below the passwords field there is an option to encrypt the file name. While testing I observed that once this option is checked, 7zCracker will not be able to extract your files. So next time you password protect your 7zip archive, make sure that you have selected an option to encrypted the files as well.

Download 7zCracker

Download 7zip Command Line Tool (7za.exe)

It works on all versions of Windows.

    Maybe it only works with the 32bit version of 7zip? I tried it with 7z archives created using 64bit version and it didn't work…

      Worked for me 5/24/2012! You never see the pw, but it extracts all the files! Fantastic. Thank you.

  • zeragual

    I've created archives with different passwords,it always writes that my password is '1' and creates empty files.

    • Nakodari

      It writes that password is 1 but the files are extracted successfully inside the 'est' folder.

      • Klaus

        No its not… check the files! They’re empty. This tool is crap. It is exactly as good as claiming the regular 7za app can extract passworded files just by entering a random password. It extracts it, but they corrupted.

        • Kenyard

          Delete the est folder and run it again. i have a core i5 and its running at 9 passwords per second all numbers atm. wud take a year to crack a basic pass :(

  • zeragual

    The length of the file is 0. I've recorded it and you can see here : http://www.youtube.com/watch?v=-keYrIDL4IY

      mate, perhaps your actual files are encrypted as mentioned, or are you extracting a self-protected 7zip ? Why i ask, is I am distributing 7zip protected works, and once we are paid, we will send the client the password. I’m just trying to find out if 7zip are secure or not, and if not what’s out there that we can use. I know zips are rars are no longer secure and havnt been for some time.

      Best regards, i hope you have more success, for your sake, and not mine ;)

  • konkandesi

    Can this work with a series of 7zip archives that belong to one set?

  • niva

    it seems it only works fine with protected 7z files created with the option “Encrypt file names” checked. otherwise, it returns an empty file with ‘1’ as a password, as mentionned by zeragual.

  • niva

    oops sorry… the editor noticed already the “Encrypt file names” trick. so you can suppress all my comments…

  • Amir

    Fortunately, this tool does not work on the latest version of 7z – April 2010

  • Jones111

    This tool is just a simple C prog that tries the password 0 to 99999999 and doesn’t show any progress nor uses letters or special chars. So it’s mainly a simple program from someone who tries to learn a programming language, nothing more. It will fail on nearly all standard passwords, has no dictionary and prints no errors on wrong usage.

    • unknown

      I agree

    • Mike

      So it’s just a really shitty brute force password cracker?

  • Tom

    Testet with some file’s

    Is this a fakeprogramm ???

  • Jones Peres

    Useless

  • xD

    after 2 h im still waiting to find the code .. this program find letters and numbers or only numbers?

  • mac

    useless! wasteoftime…

  • doom

    it can only crack number passwords!!!!!

  • DMG

    This worked for me.  Didn’t print the password it found (printed’1′) but was able to decrypt a few files and put them in an ‘est’ folder it created.

    Thanks

  • Liesontruth

    Not worth it..

  • Roy_somraj

    I have facing the same problem like others. it’s show me ” password is 1″ 

  • naji7000

    put and run all of the necessary files on your hard drive ROOT directory

  • arinjoy

    i have a rar and zip passwpord protected file which i need to convert to 7z first then crack………..how to convert without giving the password?????

  • karanp1997

    it says that archive not found even though i copy the archive name into the cracker

  • Jacob Chacko

    Thanks, it worked.

  • KP

    will this crack password for extracting .exe files for packaging purposes?

  • yoo

    28 hours and still searching… omg…

  • Fool

    Not working

  • ty

    It created all the directories and files within the .7z, but the files were all o bytes and nothing cameup when i tried to open them.

  • skidmark

    No chance i’m guessing the password, does this work or not?

  • anonymous

    Thank you so much! now all the wifi passwords are mine! (i had to d a survey to get pass to use hack)

  • Music

    THIS IS CRAP! IT SAYS TO EXTRACT THE FILE U WANT TO CRACK BUT GUESS WHAT?? I NEED THE PASSWORD TO EXTRACT THE FILE!! BULLSHIT

  • Amy Tyler

    It’s a worthless fake program. Don’t waste your time downloading this because all you will end up with in the “est” folder is what looks like your unzipped files but they will all be 0 bytes. A dog turd is more useful than this thing!

  • joe

    How did I exit the 7zcracker ?……won’t close

    • joe

      How do I*

    • ohohoh

      Ctrl-C

  • Virgil bom

  • XerosBeat
