This episode of Full Disclosure demonstrates how to hack/crack MD5 password hashes. MD5 (Message-Digest algorithm 5) is a hash function commonly used by websites to encrypt passwords. MD5 is a one-way hash; therefore, to crack the password you most try every possible dictionary word and if that does not work, every possible letter/number/symbol combination. The programs used to crack the passwords are Cain and MDCrack-NG.

Solving the Rubik's Revenge Cube is similar in concept to solving the original Rubik's Cube. You still match colors and replace one piece with another, but there is an added level of complexity. Where the classic Rubik's Cube has fixed centers that determine the color of each face, every piece on the Rubik's Revenge Cube is fully moveable. It is also much more fragile than the original Rubiks Cube therefore requires greater care and precision. If you want to more... just watch and learn.

In this tutorial, we learn how to use salty hashes to keep passwords secure. A hash is stored in a database that is hashed with an algorithm, so not everyone can see exactly what your password is. When you type your password into a website, it doesn't actually register as words, it registers as a hash. This keeps your passwords secure so not everyone can see them. Salting is when you use random pits and attaching them to your regular hashes so not every password is the same. The salt is what ...

The video shows a unique method of solving a Rubik's cube. The method is called F2LL or 'winter variation'. There is very little information about this method on the internet. It deals with Corner Orientation. The person in the video is a skilled cube handler. There are 27 algorithms and their mirrors in the F2LL method. While you form an F2LL pair, you need to orient the corners at the same time. This method makes cube solving all the more easy.
