Hashing and Cracking

Hash functions can map data of arbitrary size to data of a fixed size. (Hash functions in Wikipedia)
The ones used in cryptography are usually non-invertible.
This means that there is no easy way to reconstruct the original input. (One-way functions in Wikipedia)
However, there is a hard way: we can try all possible inputs until we find one that matches the hash. (Brute-force search in Wikipedia)

This simple app can do the following:

This is where you can hash a key:

The Dark Side

This is where you can crack:

Remember, this app will only crack key if it's max 4 characters long.
You have to paste the hash and select the hash function that was used to generate the it.
