I was looking through some of the DC404 mailing list today (as I usually do) and stumbled upon KnownPlainText.co or rather the owner’s (AverageSecurityGuy) post about his application.
Let me first state that I have not tried this application yet but will sometime this week. From what the website states it can crack many passwords in seconds using a database of hashes in the background. If it does not find a hash it will add it to the database and crack it in the background. There is also a stats page that states so far it has been able to crack 17% of the passwords run against it. This is a python application, which I like as I have been playing with python for the last week or so, so there are some prerequisites for installing on Windows (you will also need to install an application called PIP, which I imagine is some kind of framework but I am not familiar with it). This application is a paid application though it doesn’t really mention how much it costs. There is just a button for payment.
Anyway, check it out for yourself, go to:
Also check out this guys blog, seems pretty interesting:

Chase, thanks for the write up about knownplaintext.co. I have updated the site since you wrote the article and have added a buy page that specifies the license cost. You will need to download the latest version of the client before using the service. There was a logic flaw in the previous version that prevented the client from running properly.
Pip is a package installer for Python. It allows you to easily install, remove, and update Python packages. You could also use easy_installer but Pip is the recommended method.
I should also add, there is a free license that allows you to upload 100 hashes to try out the service before you buy it.
Oh Cool, I didn’t see the option for a free license. Going to give it a try tonight then I will update the article.
