====================

.. class:: AsymmetricSignatureContext

    .. versionadded:: 0.2

    .. method:: update(data)

        :param bytes data: The data you want to sign.

    .. method:: finalize()

        :return bytes signature: The signature.


.. class:: AsymmetricVerificationContext

    .. versionadded:: 0.2

    .. method:: update(data)

        :param bytes data: The data you wish to verify using the signature.

    .. method:: verify()
