SHA-2 (typically SHA-256) is an updated version of SHA-1, which adds complexity to help reduce the chance of hash collisions.
SHA-2 (typically SHA-256) is an updated version of SHA-1, which adds complexity to help reduce the chance of hash collisions.
"SHA-224," "SHA-384," and "SHA-512" are also forms of SHA-2, which are using other key lengths; the trailing number states the key length in use. The greater the key size, the more difficult it is to have a hash collision, as this produces a longer hash. For example, the text "The quick brown fox jumps over the lazy dog" using SHA-256 would produce:
