Hashing is a cryptography method that converts any form of data to a unique text string. Any piece of data can be hashed, regardless of its size or type. In traditional hashing, irrespective of the scale, type, or length of the data, the hash produced by any data is always the same length. A hash is built to act as a one-way function ... fischer combi jr
