WebFor cryptographic uses, hash functions engineered in such a way that it is impossible to reconstruct any input from the hash alone without expending vast amounts of computing time, such functions often referred to as "one-way function." Hash functions are related to (and often confused with) checksums, check digits, fingerprints, randomization ... WebIn cryptography, a salt is random data that is used as an additional input to a one-way function that hashes data, a password or passphrase. Salts are used to safeguard passwords in storage. Historically, only the output from an invocation of a cryptographic hash function on the password was stored on a system, but, over time, additional …
