ejZejZdS(s�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.
