In cryptography a hash or message digest is a fixed-size digest which can be calculated from an input text of any size up to some large limit. While cryptographic principles are used, these functions are used in manners quite different than two-way, or even one-way full-text cryptographically protected communications. The primary applications of hashes and message digests are as means of error detection, source authentication, or data integrity protection.
