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.
