WebFeb 3, 2024 · A cryptographic hash is a checksum or digital fingerprint derived by performing a one-way hash function (a mathematical operation) on the data comprising a computer program (or other digital files). Any change in just one byte of the data comprising the computer program will change the hash value. The hash value is, therefore, a unique ... WebDec 10, 2015 · A cryptographic hash function is an algorithm that takes an arbitrary amount of data input—a credential—and produces a fixed-size output of enciphered text called a hash value, or just “hash.” That enciphered text can then be stored instead of the password itself, and later used to verify the user.
