How to extract password protected RAR file?
Well First good luck and recovrring the password can take some time depending on the kind of the password. You can decompile and recompile the rar file but this is a hard work and the recovered info should be worthy of effort.
First of all, see which RAR version was used to create the archive (it makes a lot of difference if it was 2.x) and other archive characteristics like the compression method (store usually takes longer), encrypted headers (you'll need specific crackers), etc
Brute-force method: The success rate of this method depends on the length of the password, time and resources will be devoted to his research.advanced brute-force with mask attack: of you know some information about the password to recoverhttp://www.passcape.com/mask_attack.htmDecryption with an original file:This method applies to certain archive files (.

Why, with the password of course!(:
There are literally hundreds of self-proclaimed password "recovery" tools available for cracking RAR packages. Most of these "bruteforce" the password, which basically means it tries every password using a built-in dictionary list of passwords to try.
One that caught my attention is Elcomsoft's RAR Password Recovery Utility. Whichever one you choose, be sure to scan it. A bruteforcer will typically be detected as something".hacktool", anything else you should be pretty suspect of.
If it's a random file you found on the internet, you could search google for the filename and you can usually come upon a forum which someone has revealed the password (see: Google Hacking). Search using the "exact match" feature, wrapping your query around double quotes like this:
2.) "filename.rar" passwordReplace "filename" with the name of the archive you need the password of. Of course, if the name is very vague such as "program.rar" this isn't going to be very helpful.
