cti-python-stix2
================

This is an `OASIS Open
Repository <https://www.oasis-open.org/resources/open-repositories/>`__.
See the `Governance <#governance>`__ section for more information.

This repository provides Python APIs for serializing and de-serializing
STIX 2 JSON content, along with higher-level APIs for common tasks,
including data markings, versioning, and for resolving STIX IDs across
multiple data sources.

For more information, see `the
documentation <https://stix2.readthedocs.io/>`__ on
ReadTheDocs.

Installation
------------

Install with `pip <https://pip.pypa.io/en/stable/>`__:

::

    pip install stix2

Usage
-----

To create a STIX object, provide keyword arguments to the type's
constructor. Certain required attributes of all objects, such as ``type`` or
``id``,  will be set automatically if not provided as keyword arguments.

.. code:: python

    from stix2 import Indicator

    indicator = Indicator(name="File hash for malware variant",
                          labels=["malicious-activity"],
                          pattern="[file:hashes.md5 = 'd41d8cd98f00b204e9800998ecf8427e']")

To parse a STIX JSON string into a Python STIX object, use ``parse()``:

.. code:: python

    from stix2 import parse

    indicator = parse("""{
        "type": "indicator",
        "id": "indicator--dbcbd659-c927-4f9a-994f-0a2632274394",
        "created": "2017-09-26T23:33:39.829Z",
        "modified": "2017-09-26T23:33:39.829Z",
        "labels": [
            "malicious-activity"
        ],
        "name": "File hash for malware variant",
        "pattern": "[file:hashes.md5 = 'd41d8cd98f00b204e9800998ecf8427e']",
        "valid_from": "2017-09-26T23:33:39.829952Z"
    }""")
    print(indicator)

STIX 2.X Technical Specification Support
----------------------------------------

This version of python-stix2 supports STIX 2.0 by default. Although, the
`stix2` Python library is built to support multiple versions of the STIX
Technical Specification. With every major release of stix2 the ``import stix2``
statement will automatically load the SDO/SROs equivalent to the most recent
supported 2.X Technical Specification. Please see the library documentation
for more details.
