| dc:description | A cryptographic hash function is a hash function with certain additional security properties (impossible to find a (previously unseen) message that matches a given digest, impossible to find "collisions", wherein two different messages have the same message digest). A hash function takes a long string (or message) of any length as input and produces a fixed length string as output, sometimes termed a message digest or a digital fingerprint.
