„ƒYZdd„ZejZejZdS(s†SHA-256 cryptographic hash algorithm.

SHA-256 belongs to the SHA-2_ family of cryptographic hashes.
It produces the 256 bit digest of a message.

    >>> from Crypto.Hash import SHA256
    >>>
    >>> h = SHA256.new()
    >>> h.update(b'Hello')
    >>> print h.hexdigest()

*SHA* stands for Secure Hash Algorithm.
