WebJan 25, 2024 · A hash function is a versatile one-way cryptographic algorithm that maps an input of any size to a unique output of a fixed length of bits. The resulting output, which is known as a hash digest, hash value, or hash code, is the resulting unique identifier we mentioned earlier. So, why do we call it a one-way function? WebSep 18, 2013 · Hashing encryption creates a special, fixed-length signature for a message, password or set of data. Algorithms — or “hash functions” — are used to protect information, and the slightest change in info results in a completely new hash — making it incredibly difficult for hackers to invade.
