ASN.1 types and codecs

Project description

ASN.1 library for Python

This is an implementation of ASN.1 types and codecs in Python programming language. It has been first written to support particular protocol (SNMP) but then generalized to be suitable for a wide range of protocols based on ASN.1 specification.

FEATURES

  • Generic implementation of ASN.1 types (X.208)
  • Fully standard compliant BER/CER/DER codecs
  • 100% Python, works with Python 2.4 up to Python 3.3
  • MT-safe

MISFEATURES

  • No ASN.1 compiler (by-hand ASN.1 spec compilation into Python code required)
  • Codecs are not restartable

INSTALLATION

The pyasn1 package uses setuptools/distutils for installation. Thus do either:

$ easy_install pyasn1

or

$ tar zxf pyasn1-0.1.7.tar.gz

$ cd pyasn1-0.1.7

$ python setup.py install

$ python setup.py test # run unit tests

OPERATION

Perhaps a typical use would involve [by-hand] compilation of your ASN.1 specification into pyasn1-backed Python code at your application.

For more information on pyasn1 APIs, please, refer to the doc/pyasn1-tutorial.html file in the distribution.

Also refer to example modules. Take a look at pyasn1-modules package – maybe it already holds something useful to you.
