From the doc: 'This program may help you to recover a password for zip archive. Program highly optimized for speed (about 95 millions passwords per minute at modern 300 Mhz system), has nice GUI and very small. It works with archives that contains only one file and works with archives that contains files with different passwords. Program supports four types of attack: brute-force (you can define minimum and maximum password length and characters used in password), dictionary based (you can define how to modify words from dictionary file), mix of brute-force and dictionary based called template attack (if you're know something about password you can really recover it) and, finally, 'known plaintext' attack - if you have one non-encrypted file from encrypted archive you're need only 10-20 min. to recover all files from archive.'
