Decrypt password hashes super fast with Hash Toolkit. You can decode hashes into the original text. You also can generate hashes using different algorithms. Hashes are used for many applications like security, authentication and passwords.
Hash functions are built in a way that it's very easy to generate a hash / fingerprint for a text, but almost impossible to decode the hash back to the original text.
A hash, or hash function is a function that can be used to convert data of any size to a much smaller size. It's like a fingerprint of the data.
The result of a hash function are called hash code, digest, hash value or simply hash.
If the data changes just a little bit, the resulting hash will change completely.
Until now it was very difficult to reconstruct data just from the hash value. Hash Toolkit has built a giant database of precomputed inputs and their corresponding hashes. With that database it is possible to reverse / decrypt / reconstruct a hash into it's initial form in super fast way.

In cryptography, a hash function is a algorithm that is mapping data of any size to a string of a fixed size. The input is called message or simply input string. The fixed-size string function output is known as the hash or the message digest. Hash functions used in cryptography have the following key properties:
