Best rar/zip password remover - ralf93 - 04-13-2014
Hey guys i was wondering if there is another way to crack zip/rar password than brute force as it takes alot of time and since the most famous converting it to zip doesnt work anymore.
Any suggestions?

Make a tool and use a dictionary of password to crack the zip

make a bruteforce or buy it I don't know

yeah i guess there's no way other than dictionary or brute, anyways thanks for suggestions.
what i meant to ask was what is the mechanics behind zip/rar password protection or how is a file password protected to that maybe i can find another way to remove it

The chances youll successfully brute force a password protected rar file are really low but sure give it a shot.

The original PKZip has a vulnerability that enables you to appy a known plaintext attack: https://www.unix-ag.uni-kl.de/~conrad/krypto/pkcrack.html
However this is not used that much anymore. Most zip files today are encrypted with AES.
You probably won't have much more possibilities. If you really want to know how stuff works, look into the specification of the ZIP file format and also search for ZIP file exploits to get to know more possibilities for cracking the file format.
