A set of cryptographic hash functions provided by the operating system, when available. The purpose of this crate is to provide access to hash algorithms. Feb 18, 2018 ... How Cryptographic Hash Functions Solve a Very Difficult and Important Problem · Standard length — same output length, regardless of the length ... A cryptographic hash function is a procedure that returns a fixed-size bit string (hash value) for a block of data (usually the message to be sent). A cryptographic hash function is a mathematical algorithm that transforms input data of any size into a fixed-size string of characters.
