    Recover passworded winrar file

    Recover passworded winrar file 5th Dec 17 at 7:33 PM
    I have a winrar passworded .rar file I saved and password protected a year or two ago. I've since forgotten the password I used, and the contents of the file are valuable to me. I've looked around the net and there seems to me to be so many 'solutions' using software that looks a little iffy to me.
    Can anyone suggest a recovery solution that works for sure? I'd pay for a software that can be trusted to work.

    This is free, runs on the command line:
    http://www.crark.net/

    Note that if your password is super-super long, it may take a while if at all to find it.

    I'll have a look at that, thanks. Though I've not used the command line much before.

    Dictionary attack is fast if you used words or phrases or something that gets used a lot.

    Super fast compared to a force attack, although my dictionary file has grown somewhat since i first used it.
    Punctuation, Spelling and Grammar will be used sparingly. Due to rising costs of inflation.

    My contribution to MSE. Other contributions will only be used if they cost me nothing.

    Due to me being a tight git.

    I thought I'd revisit this, I'd forgotten about the file and it's still passworded!

    Does anyone have a Winrar password recovery programme they can recommend, I'm happy to pay for a programme that works. Searches bring up lots of dodgy 'free' software.

    All you can realistically do is throw a dictionary-based attack at the file such as the took I linked to above. The reason is explained on the above site, I have emphasised the key bits:

    RAR/WinRAR archiver version 2.x used its proprietary, but rather strong encryption algorithm. At least no RAR 2.0 attacks were known except brute force for password recovery

    Starting from version 3.0, RAR has been using a strong AES algorithm, which also doesn't allow any attacks more effective than the brute force. ... brute force on modern CPU only [throws] several hundreds passwords per second.

    RAR 5.0 encryption is the same, [but] the rate is even slower (25-100% on different hardware comparing to RAR 3.0). This carries inference that RAR password encryption is one of the strongest [out there].
    TL;DR - you're probably stuffed in all honesty. If your password was more than probably eight characters long, you'll have little chance of getting it back quickly if at all. You may as well just find a program such as above and let it run for a few days, cross your fingers, toes and other sticky-out bits and hope for the best.

    At the risk of sounding flippant, maybe the moral of the story is if you're going to password a file, try and remember your password

    Flippant is ok. I knew passwording that file wasn't a good idea, but I just had to do it. *sigh*

    Holy smokes, I just managed to get the password, this has been on my mind for months on and off, and I've just got it! I'm happy!

    My god.

    Glad there was a good outcome here. Others may not be so lucky.

    Moral of the story... write your passwords down on paper (good idea). Even better idea, don't set a password after a glass of wine (or other alcohol drink).

    Really, you should store your passwords in an encrypted file.
    Or use a password manager...

    Recover passworded winrar file
    So you need to know about the method to find the password of a WinRAR file. I will share one of my experience, which will help you to address the issue. Recently I downloaded a game file from torrent and well same thing happened to me. It has a password and i tried searching for internet for hours to get a solution.
