Crack Password Protected Zip Files with fcrackzip

Why, the hell, another zip cracker? fcrackzip isn’t just any other file cracker, it is quiet old (born in 1998) and I believe the last version was from 2004. However it is simple mentioned for being the first open-sourced zip-cracker out there.

fcrackzip searches each zipfile given for encrypted files and tries to guess the password. All files must be encrypted with the same password, the more files you provide, the better.

FCrackZip is The Ultimate password cracker for zip archives fcrackzip is a fast password cracker partly written in assembler. It is able to crack password protected zip files with brute force or dictionary based attacks, optionally testing with unzip its results.

It can also crack cpmask’ed images.
