========
Overview
========
Python-ASN1 is a simple ASN.1 encoder and decoder for Python 2.7 and 3.5+.
Features
========
- Support BER (parser) and DER (parser and generator) encoding (except indefinite lengths)
- 100% python, compatible with version 2.7, 3.5 and higher
- Can be integrated by just including a file into your project
Dependencies
==============
Python-ASN1 relies on `Python-Future <https://python-future.org>`_ for Python 2 and 3 compatibility. To install Python-Future:
.. code-block:: sh
pip install future
How to install Python-asn1
==========================
Install from PyPi with the following:
.. code-block:: sh
pip install asn1
or download the repository from `GitHub <https://github.com/andrivet/python-asn1>`_ and install with the following:
.. code-block:: sh
python setup.py install
You can also simply include ``asn1.py`` into your project.
How to use Python-asn1
======================
.. note:: You can find more detailed documentation on the `Usage`_ page.
.. _Usage: usage.rst
Encoding
--------
If you want to encode data and retrieve its DER-encoded representation, use code such as:
.. code-block:: python
import asn1
encoder = asn1.Encoder()
encoder.start()
encoder.write('1.2.3', asn1.Numbers.ObjectIdentifier)
encoded_bytes = encoder.output()
Decoding
--------
If you want to decode ASN.1 from DER or BER encoded bytes, use code such as:
.. code-block:: python
import asn1
decoder = asn1.Decoder()
decoder.start(encoded_bytes)
tag, value = decoder.read()
Documentation
=============
The complete documentation is available on Read The Docs:
`python-asn1.readthedocs.io <https://python-asn1.readthedocs.io/en/latest/>`_
