"""SHA-224 cryptographic hash algorithm.

SHA-224 belongs to the SHA-2_ family of cryptographic hashes.
It produces the 224 bit digest of a message.

>>> from Crypto.Hash import SHA224
    >>>
    >>> h = SHA224.new()
    >>> h.update(b'Hello')
    >>> print h.hexdigest()

*SHA* stands for Secure Hash Algorithm.
