"""SHA-384 cryptographic hash algorithm.

SHA-384 belongs to the SHA-2_ family of cryptographic hashes.
It produces the 384 bit digest of a message.

>>> from Crypto.Hash import SHA384
    >>>
    >>> h = SHA384.new()
    >>> h.update(b'Hello')
    >>> print h.hexdigest()

*SHA* stands for Secure Hash Algorithm.
