WebA cryptographic hash function is a hash function which takes an input (or 'message') and returns a fixed-size string of bytes. The string is called the 'hash value', 'message digest', 'digital fingerprint', 'digest' or 'checksum'. The ideal hash function has three main properties: It is extremely easy to calculate a hash for any given data.

Checksums are used as cryptographic primitives in larger authentication algorithms. For cryptographic systems with these two specific design goals [clarification needed], see HMAC. graduation bottle

"An important application of secure hashes is the verification of message integrity. Comparing message digests (hash digests over the message) calculated before, and after, transmission can determine whether any changes have been made to the message or file. MD5, SHA-1, or SHA-2 hash digests are sometimes published on websites or forums to allow verification of integrity for downloaded files, including files retrieved using file sharing such as mir… " - Cryptographic hash function applications
