.. class:: Sha256

    Computes the SHA-256 hash of a piece of data.

    .. method:: this()

        `this()`

        Create a new instance.

    .. method:: update(data)

        `void update(ubyte[] data)`

        Update the hash for a block of data.

        The result for calling update multiple times is
        the same as if update had been called once with all
        data.

    .. method:: finalize()

        `ubyte[] finalize()`

        Return the hash value.

        `update` must not be called past this point.
