Internationalized Domain Names in Applications (IDNA)
|
||||
=====================================================
|
||||
|
||||
Support for `Internationalized Domain Names in
|
||||
Applications (IDNA) <https://tools.ietf.org/html/rfc5891>`_
|
||||
and `Unicode IDNA Compatibility Processing
|
||||
<https://unicode.org/reports/tr46/>`_.
|
||||
|
||||
The latest versions of these standards supplied here provide
|
||||
more comprehensive language coverage and reduce the potential of
|
||||
allowing domains with known security vulnerabilities. This library
|
||||
is a suitable replacement for the “encodings.idna”
|
||||
module that comes with the Python standard library, but which
|
||||
only supports an older superseded IDNA specification from 2003.
|
||||
|
||||
Basic functions are simply executed:
|
||||
|
||||
.. code-block:: pycon
|
||||
|
||||
>>> import idna
|
||||
>>> idna.encode('ドメイン.テスト')
|
||||
b'xn--eckwd4c7c.xn--zckzah'
|
||||
>>> print(idna.decode('xn--eckwd4c7c.xn--zckzah'))
|
||||
ドメイン.テスト
|
||||
|
||||
|
||||
Installation
|
||||
------------
|
||||
|
||||
This package is available for installation from PyPI via the
|
||||
typical mechanisms, such as:
|
||||
|
||||
.. code-block:: bash
|
||||
|
||||
$ python3 -m pip install idna
|
||||
|
||||
|
||||
Usage
|
||||
-----
|
||||
|
||||
For typical usage, the ``encode`` and ``decode`` functions will take a
|
||||
domain name argument and perform a conversion to ASCII compatible encoding
|
||||
(known as A-labels), or to Unicode strings (known as U-labels)
|
||||
respectively.
|
||||
|
||||
.. code-block:: pycon
|
||||
|
||||
>>> import idna
|
||||
>>> idna.encode('ドメイン.テスト')
|
||||
b'xn--eckwd4c7c.xn--zckzah'
|
||||
>>> print(idna.decode('xn--eckwd4c7c.xn--zckzah'))
|
||||
ドメイン.テスト
|
||||
|
||||
Conversions can be applied at a per-label basis using the ``ulabel`` or
|
||||
``alabel`` functions if necessary:
|
||||
|
||||
.. code-block:: pycon
|
||||
|
||||
>>> idna.alabel('测试')
|
||||
b'xn--0zwm56d'
|
||||
|
||||
|
||||
Compatibility Mapping (UTS #46)
|
||||
+++++++++++++++++++++++++++++++
|
||||
|
||||
This library provides support for `Unicode IDNA Compatibility
|
||||
Processing <https://unicode.org/reports/tr46/>`_ which normalizes input from
|
||||
different potential ways a user may input a domain prior to performing the IDNA
|
||||
conversion operations. This functionality, known as a
|
||||
`mapping <https://tools.ietf.org/html/rfc5895>`_, is considered by the
|
||||
specification to be a local user-interface issue distinct from IDNA
|
||||
conversion functionality.
|
||||
|
||||
For example, “Königsgäßchen” is not a permissible label as *LATIN
|
||||
CAPITAL LETTER K* is not allowed (nor are capital letters in general).
|
||||
UTS 46 will convert this into lower case prior to applying the IDNA
|
||||
conversion.
|
||||
|
||||
.. code-block:: pycon
|
||||
|
||||
>>> import idna
|
||||
>>> idna.encode('Königsgäßchen')
|
||||
...
|
||||
idna.core.InvalidCodepoint: Codepoint U+004B at position 1 of 'Königsgäßchen' not allowed
|
||||
>>> idna.encode('Königsgäßchen', uts46=True)
|
||||
b'xn--knigsgchen-b4a3dun'
|
||||
>>> print(idna.decode('xn--knigsgchen-b4a3dun'))
|
||||
königsgäßchen
|
||||
|
||||
|
||||
Exceptions
|
||||
----------
|
||||
|
||||
All errors raised during the conversion following the specification
|
||||
should raise an exception derived from the ``idna.IDNAError`` base
|
||||
class.
|
||||
|
||||
More specific exceptions that may be generated as ``idna.IDNABidiError``
|
||||
when the error reflects an illegal combination of left-to-right and
|
||||
right-to-left characters in a label; ``idna.InvalidCodepoint`` when
|
||||
a specific codepoint is an illegal character in an IDN label (i.e.
|
||||
INVALID); and ``idna.InvalidCodepointContext`` when the codepoint is
|
||||
illegal based on its position in the string (i.e. it is CONTEXTO or CONTEXTJ
|
||||
but the contextual requirements are not satisfied.)
|
||||
|
||||
Building and Diagnostics
|
||||
------------------------
|
||||
|
||||
The IDNA and UTS 46 functionality relies upon pre-calculated lookup
|
||||
tables for performance. These tables are derived from computing against
|
||||
eligibility criteria in the respective standards using the command-line
|
||||
script ``tools/idna-data``.
|
||||
|
||||
This tool will fetch relevant codepoint data from the Unicode repository
|
||||
and perform the required calculations to identify eligibility. There are
|
||||
three main modes:
|
||||
|
||||
* ``idna-data make-libdata``. Generates ``idnadata.py`` and
|
||||
``uts46data.py``, the pre-calculated lookup tables used for IDNA and
|
||||
UTS 46 conversions. Implementers who wish to track this library against
|
||||
a different Unicode version may use this tool to manually generate a
|
||||
different version of the ``idnadata.py`` and ``uts46data.py`` files.
|
||||
|
||||
* ``idna-data make-table``. Generate a table of the IDNA disposition
|
||||
(e.g. PVALID, CONTEXTJ, CONTEXTO) in the format found in Appendix
|
||||
B.1 of RFC 5892 and the pre-computed tables published by `IANA
|
||||
<https://www.iana.org/>`_.
|
||||
|
||||
* ``idna-data U+0061``. Prints debugging output on the various
|
||||
properties associated with an individual Unicode codepoint (in this
|
||||
case, U+0061), that are used to assess the IDNA and UTS 46 status of a
|
||||
codepoint. This is helpful in debugging or analysis.
|
||||
|
||||
The tool accepts a number of arguments, described using ``idna-data
|
||||
-h``. Most notably, the ``--version`` argument allows the specification
|
||||
of the version of Unicode to be used in computing the table data. For
|
||||
example, ``idna-data --version 9.0.0 make-libdata`` will generate
|
||||
library data against Unicode 9.0.0.
|
||||
|
||||

||||
Additional Notes
|
||||
----------------
|
||||
|
||||
* **Packages**. The latest tagged release version is published in the
|
||||
`Python Package Index <https://pypi.org/project/idna/>`_.
|
||||
|
||||
* **Version support**. This library supports Python 3.8 and higher.
|
||||
As this library serves as a low-level toolkit for a variety of
|
||||
applications, many of which strive for broad compatibility with older
|
||||
Python versions, there is no rush to remove older interpreter support.
|
||||
Support for older versions are likely to be removed from new releases
|
||||
as automated tests can no longer easily be run, i.e. once the Python
|
||||
version is officially end-of-life.
|
||||
|
||||
* **Testing**. The library has a test suite based on each rule of the
|
||||
IDNA specification, as well as tests that are provided as part of the
|
||||
Unicode Technical Standard 46, `Unicode IDNA Compatibility Processing
|
||||
<https://unicode.org/reports/tr46/>`_.
|
||||
|
||||
* **Emoji**. It is an occasional request to support emoji domains in
|
||||
this library. Encoding of symbols like emoji is expressly prohibited by
|
||||
the technical standard IDNA 2008 and emoji domains are broadly phased
|
||||
out across the domain industry due to associated security risks. For
|
||||
now, applications that need to support these non-compliant labels
|
||||
may wish to consider trying the encode/decode operation in this library
|
||||
first, and then falling back to using `encodings.idna`. See `the Github
|
||||
project <https://github.com/kjd/idna/issues/18>`_ for more discussion.
|
||||
|
||||
* **Transitional processing**. Unicode 16.0.0 removed transitional
|
||||
processing so the `transitional` argument for the encode() method
|
||||
no longer has any effect and will be removed at a later date.
