With Hash Toolkit you can decrypt hashes into the original text. You also can generate hashes using different algorithms. Hashes are used for many applications like security, authentication and others.
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 you can reverse / decrypt / reconstruct a hash into it's initial form super fast.
