Crack MD5 v.03
by ZoneDevil (hackedbydevil404@gmail.com)
April 2011
GNU General Public License, have fun with it
Light-force crack of exposed MD5 hashes
- "Light-force" because we're not brute-forcing through a huge database of decrypted keys.
You can do that all over the internet (shout out to gdataonline.com). We're just showing
proof-of-concept by using search engines to find keys and their plaintext.
- We do use our own database to store successful deciphers made from this application. Mainly
because we're limited to a certain amount of API calls per day on Yahoo and Google. (Update:
database support removed for simplicity. It's easy enough to add your own, and we will
put database support back in if the API calls get limited by the search engines)
- Theoretically, if enough pages of hash / plaintext combinations were cataloged by seach
engines across the internet, we could use the processing power of Google and Yahoo to search
much more efficiently than searching millions of rows in a database
- We search Google first, because if there are search results returned, the plaintext is almost
always found in the page summary. With Yahoo we have to do a bit more checking.
Changelog
# version .02:
- added database support for caching found hashes
- changed regex's a little (still need some vodoo to make them more efficient)
- organized the code to be more modular
- added memory limits because it crashed when a large html page was loaded
(instead of skipping this page we might need to figure out how to better parse it into manageable chunks)
- now searches Yahoo's summary field for each page (as well as the URL name and page content)
- added debug content
- made user agent show $_SERVER['HTTP_USER_AGENT'] instead of "spider"
# version .03:
- added upper/lower case hash searches, and searches with punctuation removed
- added Google search (without API)
- fixed sorting bug where keys were being lost
- made use of php's parse_url instead of homegrown verison
- made regular expressions more efficient
- removed dependency on external filter for cleaning input
- removed references to database (add your own if you want to use a database as a backup for stored hashes)
