ejZdS )a�  SHA-1 cryptographic hash algorithm.
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.

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