QuestionQ219

VerifiedCryptography

What is the term for a one-way transformation that converts a character string into a typically shorter, fixed-length value or key representing the original string, and that cannot be reversed?

Explanation

A one-way hash transforms input data into a fixed-length hash value (digest) that represents the input and is designed not to be reversed to recover the original data. DES, transposition, and substitution are encryption or cipher techniques rather than one-way hashing.
