Instance Method


Finalizes the hash function and returns the computed digest.


func finalize() -> SHA256.Digest

Return Value

The computed digest of the data.


Call this method after you provide the hash function with all the data to hash by making one or more calls to the update(data:) or update(bufferPointer:) method. After finalizing the hash function, discard it. To compute a new digest, create a new hash function with a call to the init() method.
