A hash is a one-way digest function. It takes a number of input bytes and computes a fixed-length value from it. If you compute the same hash again, you get the same result. Generally the numeric value of the length of the input is not considered, as the data is inherently changed if you change the length. Hashes cannot be decrypted.
