RAR Password Cracker is a handy tool that allows you to crack open RAR files without needing the password stated. Since its name is straightforward, it will only work with RAR files and not ZIP or any other extensions. This program is also good for when you forget a password on a .RAR and you need to recover it so you can grab the files within. This software comes with an option called Brute force attack, which determines random sequences of letters and numbers to try to crack open the original password.
There is another method to open up a password as well, Dictionary attack. This will go through a list of dictionary words that you have created to try to understand the password. Dictionary attack will need to have separate dictionary files uploading in order to process. You can also save the password recoveries for future use, especially if you plan on using the same password for your own files and you need to remember the sequence.
RAR Password Cracker has a simple interface and gets straight to the point, asking you which mode you'd like to use to crack the passcode. As basic as it looks, it really does help crack open tough passwords and is very efficient while doing so. The only con to this program is that it isn't very speedy, in fact it can be super slow at times, depending on how long the password sequence is.
If you're forget with your .RAR files or want to use it for another purpose, this free software is your best bet despite its slow progession speed.
