Hash function sha-2
WebFeb 17, 2024 · The SHA-2 family of hashing algorithms are the most common hash functions in use. SHA-256 is particularly widespread. … WebDec 4, 2014 · The best standardized algorithm currently available is still SHA-2. SHA-2 now consists of 6 hash functions: SHA-256, SHA-384 and SHA-512 were first defined. SHA-224 was later added to allow for a smaller output size. After that the less well available SHA-512/224 and SHA-512/256 were introduced.
