WebJun 22, 2024 · Overview. 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 ... WebAn example This example uses the common unix utility "md5sum", which hashes the data on stdin to a 128 bit hash, displayed as 32 hex digits.
