    The program simply does a loop and tries numeric passwords from 1 to 99,999,999 if I read the source correctly, so it won't find any alphanumeric passwords or dictionary words etc. Lots of room for improvement.

    It's a hoax just waists the users time.

    This program is designed to break weak password encrypted 7z files, there is nothing on earth that can break one with a strong password so don't expect it to. This is a good last ditch effort to see if they have an easy password on the file before giving up (or going all Jack Bauer on the maker and beating the password out of him). Here are the time ranges for various lower case alphanumeric lengths (assuming 10 per second). 1: 0-3.6sec 2: 2.6sec-129.6sec 3: 129.6sec-1.3hours 4: 1.3 hours-46.7hrs 5: 46.7hrs-70 days 6: 70 days-6.9 years 7: 6.9 years-248 years 8: 248 years-8,946 years 9: 8,946 years-322,045 years 10: 322,045 years-11,593,602 years Once again, its only useful for small passwords. edit: But upon actually using it for a weak password it doesn't even work.
