This means that, in addition to the basic transformation operation, SHA-1 also guarantees certain security properties. Cryptographic hashing algorithms have two core characteristics: (1) Hash digests are unique. (2) Hashes cannot be reversed. There are many cryptographic hash algorithms; this section lists a few algorithms that are referenced relatively often. A more extensive list can be found on the page containing a comparison of cryptographic hash functions.
