A rainbow table can be thought of like a dictionary, except instead of words and their definitions, it holds combinations of characters on one side and their hashed form on the other. What is a hash and why would you want to know what random combinations of characters are hashed into?

Have you ever wondered how credit card numbers work? I mean, how they really work? How do they come up with the numbers? Credit cards actually follow a very specific pattern. Let's take a look at how they're set up.
In Linux, all password hashes are normally stored using the MD5 hashing algorithm in the /etc/shadow file, but MD5 is algorithmically weak due to collision vulnerabilities. The new recommended standard are the higher level SHA-2 hashing algorithms, SHA256 or SHA512. As a friend pointed out to me, Ubuntu is currently the only distro implementing SHA-2 as the default. With SHA-2, your passwords take an unreasonably larger amount of time to calculate. This will greatly decrease how many password...

This video tutorial is for beginner puzzlers who are getting more advanced in their speedsolving of the Rubik's Cube. When solving the Rubiks Cube, there are these mathematical equations called algorithms, which I'm sure you already know. But wait... what do algorithms have to do with notation? Well, in an algorithm you have a sequence of letters that tell you which sides of the cube you want to turn. Each of the six sides of the Rubik's Cube are associated with a letter and a symbol that tel...
You have a Rubik's Cube, maybe your mother gave it to you for your birthday, maybe you actually bought it for yourself, or maybe you just found that colorful puzzle cube in the gutter, but either way... you don't know how to solve it.
Erno Rubik's Magic Cube is a puzzle that's been frustrating people since its release in the early seventies. Erno's mystifying three-dimensional puzzle cube consists of 6 faces, 26 cubes and 54 stickers of solid colors (traditionally white, red, blue, orange, green, and yellow). The Magic Cube morphed into what is now known as the Rubik's Cube, and is one of the best selling toys on the market today.

Watch this video tutorial to see how to solve the acid cube Square One puzzle. There's a few things you should know before even trying to solve the Square-1 puzzle, which is knowing how to solve the Rubik's Cube. Then you need to know the notation for rotating the Square One, also known as Back to Square One and Cube 21. Next you need to know a few algorithms and you're halfway to solving the challenging puzzle.

So, you can solve the Rubik's Cube, good for you, but what about the Square One? Erno Rubik is nothing compared to Karel Hršel and Vojtech Kopský, who invented the Square One puzzle, also called by its full title, "Back to Square One", or its shorter name of "Cube 21". It's shaped like a Rubik's Cube, but it's cut like a freak show, adding that layer of difficulty that challenges you.
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.
Ever hear of a Rubik's Cube, well, did you know that some people can actually solve the mighty puzzle? Yes, that right, they sure can, and so can you... maybe.
This video tutorial is for beginner puzzlers who are getting more advanced in their speedsolving of the Rubik's Cube. This 2-Look Method is exactly like taking 57 OLL algorithms and slimming them down to the single digits. First you orient the edges of the Rubiks Cube (or the cross if you prefer), then the corners, hence the name "2-Look OLL".
