typealias SHA2_256 = SHA256

An implementation of Secure Hashing Algorithm 2 (SHA-2) hashing with a 256-bit digest. The ``SHA2_256`` hash implements the ``HashFunction`` protocol for the specific case of SHA-2 hashing with a 256-bit digest (``SHA256Digest``). Larger digests take more space but are more secure. You can compute the digest by calling the static ``hash(data:)`` method once. Alternatively, if the data that you want to hash is too large to fit in memory, you can compute the digest iteratively by creating a new hash instance, calling the ``update(data:)`` method repeatedly with blocks of data, and then calling the ``finalize()`` method to get the result.
