a� 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.

:Parameters:
data : byte string
The very first chunk of the message to hash.
It is equivalent to an early call to `SHA256Hash.update()`.
Optional.
:Return: A `SHA256Hash` object
