    How to Crack rar, zip and PDF password


    ......Cracking rar passwords

    The only free software to crack rar passwords is from http://www.crark.net. Version 3.2a adds CUDA support for Nvidia video card to increase cracking speed by up 15x. The source code is at http://www.crark.net/Cuda- OpenSrc.rar and binaries are available.
    Next there is rarcrack. You can download the source code from http://sourceforge.net/projects/rarcrack/. You can read how to use rarcrack at http://www.mydigitallife.info/2009/01/06/how-to-recover-rar-7z-and-zip- password-with-rarcrack-in-linux/
    You can also use Advanced Archive Password Recovery from http://www.elcomsoft.com/archpr.html to recover the password. Advanced Archive Password Recovery is not free. The advantage to Advanced Archive Password Recovery is that it supports a wide range of encryption and compression algorithms.
    Finally cracking the password takes time. If you really need into that file you can just remove the password using winrar_unlock from http://www.mydigitallife.info/2008/11/30/winrar-unlock-free-download-to-unlock- locked-protected-rar-archive-support-sfx-exe/
    ......Cracking zip passwords
    You can use rarcrack to crack zip and 7z files. The source code is available from http://sourceforge.net /projects/rarcrack/.
    fcrackzip is another tool to crack zip passwords. You can download the source code and windows binary from http://home.schmorp.de/marc/fcrackzip.html
    Finally cracking the password takes time. If you really need into that file you should just try to remove the password.
    ......Cracking pdf passwords

    There are two types of pdf passwords user and owner. A user password is set when the author of the pdf wants the end user to enter a password to view the pdf. In other words the password has to be entered each time the pdf is opened. The owner password is set when the author wants to prevent the person viewing the pdf from changing the permissions of the restricted features. If both passwords are set either password can open the document. However only the owner password can change permissions.
    You can use PDFCrack to crack password protected pdf files. The source code is available from http://pdfcrack.sourceforge.net/. PDF Crack is made for Linux however it should work for any POSIX compatible system. rubypdf created a windows binary of PDFCrack using Cygwin. You can read about it at http://sourceforge.net/projects/pdfcrack/forums/forum/575585/topic/2224035. If your computer has a multi-core processor you might want to apply the following patch to PDFCrack http://sourceforge.net/projects /pdfcrack/forums/forum/575585/topic/3364643. This patch adds support for multi-core processors and speeds up the cracking process and yes there is a windows binary available.
    GuaPDF available from http://www.guapdf.com/ can also crack password protected pdf files. GuaPDF can remove the restrictions of any password protected pdf. This includes support for Adobe 9 with 256 bit AES and 128 bit RC4 encryption. The removal process is instantanous. Note that only standard pdf security is supported. Cracking of third-party plugins and/or e-books is not supported. GuaPDF is supported on Linux, Windows, Solaris, DOS, and Mac OS. It supports multi-core processors and NVIDIA GPU cards. GuaPDF will remove restrictions from small pdf files for free. For larger files or a version that supports distributed cracking the program you must pay for the program.
    Elcomsoft also makes a pdf password recovery program. It can be found at http://www.elcomsoft.com /apdfpr.html. Advanced PDF Password Recovery can remove both the user and owner passwords as well as remove any restrictions.
    You can also try to open the PDF and print it to another pdf creater to remove the restrictions.
    Finally cracking the password takes time. If you really need into that file you should just try to remove the password.
