subresource-integrity

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

A Python package to create and parse `Subresource Integrity`_ values.

Installation

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

.. code:: shell

    pip install subresource-integrity

Usage

=====

Render an integrity value, given the content

.. code:: python

    >>> import subresource_integrity as integrity

    >>> data = b"alert('Hello, world.');"

    >>> integrity.render(data)

    'sha384-H8BRh8j48O9oYatfu5AZzq6A9RINhZO5H16dQZngK7T62em8MUt1FLm52t+eX6xO'

Render multiple integrity values for the same content

.. code:: python

    >>> hashes = list(integrity.generate(data, ['sha384', 'sha256']))

    >>> [str(h) for h in hashes] # doctest: +NORMALIZE_WHITESPACE

    ['sha384-H8BRh8j48O9oYatfu5AZzq6A9RINhZO5H16dQZngK7T62em8MUt1FLm52t+eX6xO',

     'sha256-qznLcsROx4GACP2dm0UCKCzCG+HiZ1guq6ZZDob/Tng=']

Parse several space-delimited integrity values, and iterate of them

.. code:: python

    >>> parsed = integrity.parse(' sha256-47DEQpj8HBSa+/TImW+5JCeu'

    ...                          'QeRkm5NMpJWZG3hSuFU= ')

    >>> parsed # doctest: +ELLIPSIS

    [subresource_integrity.Hash('sha256', '47DEQp...SuFU=', '')]

    >>> [str(h) for h in parsed]

    ['sha256-47DEQpj8HBSa+/TImW+5JCeuQeRkm5NMpJWZG3hSuFU=']
