9 Attacks on cryptographic hash algorithms.6 Use in building other cryptographic primitives.4 Hash functions based on block ciphers.3.2 Signature generation and verification.3.1 Verifying the integrity of messages and files.Indeed, in information-security contexts, cryptographic hash values are sometimes called ( digital) fingerprints, checksums, or just hash values, even though all these terms stand for more general functions with rather different properties and purposes. They can also be used as ordinary hash functions, to index data in hash tables, for fingerprinting, to detect duplicate data or uniquely identify files, and as checksums to detect accidental data corruption.
