SHA-1_ produces the 160 bit digest of a message.
>>> from Crypto.Hash import SHA
>>>
>>> h = SHA.new()
>>> h.update(b'Hello')
>>> print h.hexdigest()
*SHA* stands for Secure Hash Algorithm.
This algorithm is not considered secure. Do not use it for new designs.

The very first chunk of the message to hash.
It is equivalent to an early call to `SHA1Hash.update()`.
Optional.
