This package contains a modified version of ca-bundle.crt:
|
||||
|
||||
ca-bundle.crt -- Bundle of CA Root Certificates
|
||||
|
||||
This is a bundle of X.509 certificates of public Certificate Authorities
|
||||
(CA). These were automatically extracted from Mozilla's root certificates
|
||||
file (certdata.txt). This file can be found in the mozilla source tree:
|
||||
https://hg.mozilla.org/mozilla-central/file/tip/security/nss/lib/ckfw/builtins/certdata.txt
|
||||
It contains the certificates in PEM format and therefore
|
||||
can be directly used with curl / libcurl / php_curl, or with
|
||||
an Apache+mod_ssl webserver for SSL client authentication.
|
||||
Just configure this file as the SSLCACertificateFile.#

Certifi: Python SSL Certificates
|
||||
================================
|
||||
|
||||
Certifi provides Mozilla's carefully curated collection of Root Certificates for
|
||||
validating the trustworthiness of SSL certificates while verifying the identity
|
||||
of TLS hosts. It has been extracted from the `Requests`_ project.
|
||||
|
||||
Installation
|
||||
------------
|
||||
|
||||
``certifi`` is available on PyPI. Simply install it with ``pip``::
|
||||
|
||||
$ pip install certifi
|
||||
|
||||
Usage
|
||||
-----
|
||||
|
||||
To reference the installed certificate authority (CA) bundle, you can use the
|
||||
built-in function::
|
||||
|
||||
>>> import certifi
|
||||
|
||||
>>> certifi.where()
|
||||
'/usr/local/lib/python3.7/site-packages/certifi/cacert.pem'
|
||||
|
||||
Or from the command line::
|
||||
|
||||
$ python -m certifi
|
||||
/usr/local/lib/python3.7/site-packages/certifi/cacert.pem
|
||||
|
||||
Enjoy!
|
||||
|
||||
.. _`Requests`: https://requests.readthedocs.io/en/master/
|
||||
|
||||
Addition/Removal of Certificates
|
||||
--------------------------------
|
||||
|
||||
Certifi does not support any addition/removal or other modification of the
|
||||
CA trust store content. This project is intended to provide a reliable and
|
||||
highly portable root of trust to python deployments. Look to upstream projects
|
||||
for methods to use alternate trust.

## ⚡ Performance
|
||||
|
||||
This package offer better performance than its counterpart Chardet. Here are some numbers.
|
||||
|
||||
| Package | Accuracy | Mean per file (ms) | File per sec (est) |
|
||||
|-----------------------------------------------|:--------:|:------------------:|:------------------:|
|
||||
| [chardet](https://github.com/chardet/chardet) | 86 % | 63 ms | 16 file/sec |
|
||||
| charset-normalizer | **98 %** | **10 ms** | 100 file/sec |
|
||||
|
||||
| Package | 99th percentile | 95th percentile | 50th percentile |
|
||||
|-----------------------------------------------|:---------------:|:---------------:|:---------------:|
|
||||
| [chardet](https://github.com/chardet/chardet) | 265 ms | 71 ms | 7 ms |
|
||||
| charset-normalizer | 100 ms | 50 ms | 5 ms |
|
||||
|
||||
_updated as of december 2024 using CPython 3.12_
|
||||
|
||||
Chardet's performance on larger file (1MB+) are very poor. Expect huge difference on large payload.
|
||||
|
||||
> Stats are generated using 400+ files using default parameters. More details on used files, see GHA workflows.
|
||||
> And yes, these results might change at any time. The dataset can be updated to include more files.
|
||||
> The actual delays heavily depends on your CPU capabilities. The factors should remain the same.
|
||||
> Keep in mind that the stats are generous and that Chardet accuracy vs our is measured using Chardet initial capability
|
||||
> (e.g. Supported Encoding) Challenge-them if you want.
|
||||
|
||||
## ✨ Installation
|
||||
|
||||
Using pip:
|
||||
|
||||
```sh
|
||||
pip install charset-normalizer -U
|
||||
```
|
||||
|
||||
## 🚀 Basic Usage
|
||||
|
||||
### CLI
|
||||
This package comes with a CLI.
|
||||
|
||||
```
|
||||
usage: normalizer [-h] [-v] [-a] [-n] [-m] [-r] [-f] [-t THRESHOLD]
|
||||
file [file ...]
|
||||
|
||||
The Real First Universal Charset Detector. Discover originating encoding used
|
||||
on text file. Normalize text to unicode.
|
||||
|
||||
positional arguments:
|
||||
files File(s) to be analysed
|
||||
|
||||
optional arguments:
|
||||
-h, --help show this help message and exit
|
||||
-v, --verbose Display complementary information about file if any.
|
||||
Stdout will contain logs about the detection process.
|
||||
-a, --with-alternative
|
||||
Output complementary possibilities if any. Top-level
|
||||
JSON WILL be a list.
|
||||
-n, --normalize Permit to normalize input file. If not set, program
|
||||
does not write anything.
|
||||
-m, --minimal Only output the charset detected to STDOUT. Disabling
|
||||
JSON output.
|
||||
-r, --replace Replace file when trying to normalize it instead of
|
||||
creating a new one.
|
||||
-f, --force Replace file without asking if you are sure, use this
|
||||
flag with caution.
|
||||
-t THRESHOLD, --threshold THRESHOLD
|
||||
Define a custom maximum amount of chaos allowed in
|
||||
decoded content. 0. <= chaos <= 1.
|
||||
--version Show version information and exit.
|
||||
```
|
||||
|
||||
```bash
|
||||
normalizer ./data/sample.1.fr.srt
|
||||
```
|
||||
|
||||
or
|
||||
|
||||
```bash
|
||||
python -m charset_normalizer ./data/sample.1.fr.srt
|
||||
```
|
||||
|
||||
🎉 Since version 1.4.0 the CLI produce easily usable stdout result in JSON format.
|
||||
|
||||
```json
|
||||
{
|
||||
"path": "/home/default/projects/charset_normalizer/data/sample.1.fr.srt",
|
||||
"encoding": "cp1252",
|
||||

|
||||

|
||||

|
||||

|
||||

"iso8859_3",
|

|
||||
"mbcs"
|
||||
],
|
||||
"language": "French",
|
||||
"alphabets": [
|
||||
"Basic Latin",
|
||||
"Latin-1 Supplement"
|
||||
],
|
||||
"has_sig_or_bom": false,
|
||||
"chaos": 0.149,
|
||||
"coherence": 97.152,
|
||||
"unicode_path": null,
|
||||
"is_preferred": true
|
||||
}
|
||||
```
|
||||
|
||||
### Python
|
||||
*Just print out normalized text*
|
||||
```python
|
||||
from charset_normalizer import from_path
|
||||
|
||||
results = from_path('./my_subtitle.srt')
|
||||
|
||||
print(str(results.best()))
|
||||
```
|
||||
|
||||
*Upgrade your code without effort*
|
||||
```python
|
||||
from charset_normalizer import detect
|
||||
```
|
||||
|
||||
The above code will behave the same as **chardet**. We ensure that we offer the best (reasonable) BC result possible.
|
||||
|
||||
See the docs for advanced usage : [readthedocs.io](https://charset-normalizer.readthedocs.io/en/latest/)
|
||||
|
||||
## 😇 Why
|
||||
|
||||
When I started using Chardet, I noticed that it was not suited to my expectations, and I wanted to propose a
|
||||
reliable alternative using a completely different method. Also! I never back down on a good challenge!
|
||||
|
||||
I **don't care** about the **originating charset** encoding, because **two different tables** can
|
||||
produce **two identical rendered string.**
|
||||
What I want is to get readable text, the best I can.
|
||||
|
||||
In a way, **I'm brute forcing text decoding.** How cool is that ? 😎
|
||||
|
||||
Don't confuse package **ftfy** with charset-normalizer or chardet. ftfy goal is to repair Unicode string whereas charset-normalizer to convert raw file in unknown encoding to unicode.
|
||||
|
||||
## 🍰 How
|
||||
|
||||
- Discard all charset encoding table that could not fit the binary content.
|
||||
- Measure noise, or the mess once opened (by chunks) with a corresponding charset encoding.
|
||||
- Extract matches with the lowest mess detected.
|
||||
- Additionally, we measure coherence / probe for a language.
|
||||
|
||||
**Wait a minute**, what is noise/mess and coherence according to **YOU ?**
|
||||
|
||||
*Noise :* I opened hundred of text files, **written by humans**, with the wrong encoding table. **I observed**, then
|
||||
**I established** some ground rules about **what is obvious** when **it seems like** a mess (aka. defining noise in rendered text).
|
||||
I know that my interpretation of what is noise is probably incomplete, feel free to contribute in order to
|
||||
improve or rewrite it.
|
||||
|
||||
*Coherence :* For each language there is on earth, we have computed ranked letter appearance occurrences (the best we can). So I thought
|
||||
that intel is worth something here. So I use those records against decoded text to check if I can detect intelligent design.
|
||||
|
||||
## ⚡ Known limitations
|
||||
|
||||
- Language detection is unreliable when text contains two or more languages sharing identical letters. (eg. HTML (english tags) + Turkish content (Sharing Latin characters))
|
||||
- Every charset detector heavily depends on sufficient content. In common cases, do not bother run detection on very tiny content.
|
||||
|
||||
## ⚠️ About Python EOLs
|
||||
|
||||
**If you are running:**
|
||||
|
||||
- Python >=2.7,<3.5: Unsupported
|
||||
- Python 3.5: charset-normalizer < 2.1
|
||||
- Python 3.6: charset-normalizer < 3.1
|
||||
- Python 3.7: charset-normalizer < 4.0
|
||||
|
||||
Upgrade your Python interpreter as soon as possible.

Charset-Normalizer
|
||||
~~~~~~~~~~~~~~
|
||||
The Real First Universal Charset Detector.
|
||||
A library that helps you read text from an unknown charset encoding.
|
||||
Motivated by chardet, This package is trying to resolve the issue by taking a new approach.
|
||||
All IANA character set names for which the Python core library provides codecs are supported.
|
||||
|
||||
Basic usage:
|
||||
>>> from charset_normalizer import from_bytes
|
||||
>>> results = from_bytes('Bсеки човек има право на образование. Oбразованието!'.encode('utf_8'))
|
||||
>>> best_guess = results.best()
|
||||
>>> str(best_guess)
|
||||
'Bсеки човек има право на образование. Oбразованието!'
|
||||
|
||||
Others methods and usages are available - see the full documentation
|
||||
at <https://github.com/Ousret/charset_normalizer>.

|

Given a raw bytes sequence, return the best possibles charset usable to render str objects.
|
||||
If there is no results, it is a strong indicator that the source is binary/not text.
|
||||
By default, the process will extract 5 blocks of 512o each to assess the mess and coherence of a given sequence.
|
||||
And will give up a particular code page after 20% of measured mess. Those criteria are customizable at will.
|
||||
|
||||
The preemptive behavior DOES NOT replace the traditional detection workflow, it prioritize a particular code page
|
||||
but never take it for granted. Can improve the performance.
|
||||
|
||||
You may want to focus your attention to some code page or/and not others, use cp_isolation and cp_exclusion for that
|
||||
purpose.
|
||||
|
||||
This function will strip the SIG in the payload/sequence every time except on UTF-16, UTF-32.
|
||||
By default the library does not setup any handler other than the NullHandler, if you choose to set the 'explain'
|
||||
toggle to True it will alter the logger configuration to add a StreamHandler that is suitable for debugging.
|
||||
Custom logging format and handler can be set manually.

Internationalized Domain Names in Applications (IDNA)
|
||||
=====================================================
|
||||
|
||||
Support for the Internationalized Domain Names in
|
||||
Applications (IDNA) protocol as specified in `RFC 5891
|
||||
<https://tools.ietf.org/html/rfc5891>`_. This is the latest version of
|
||||
the protocol and is sometimes referred to as “IDNA 2008”.
|
||||
|
||||
This library also provides support for Unicode Technical
|
||||
Standard 46, `Unicode IDNA Compatibility Processing
|
||||
<https://unicode.org/reports/tr46/>`_.
|
||||
|
||||
This acts as a suitable replacement for the “encodings.idna”
|
||||
module that comes with the Python standard library, but which
|
||||
only supports the older superseded IDNA specification (`RFC 3490
|
||||
<https://tools.ietf.org/html/rfc3490>`_).
|
||||
|
||||
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:
|
||||
|
||||
.. 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 A-labels or 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
|
||||
|
||||
You may use the codec encoding and decoding methods using the
|
||||
``idna.codec`` module:
|
||||
|
||||
.. code-block:: pycon
|
||||
|
||||
>>> import idna.codec
|
||||
>>> print('домен.испытание'.encode('idna2008'))
|
||||
b'xn--d1acufc.xn--80akhbyknj4f'
|
||||
>>> print(b'xn--d1acufc.xn--80akhbyknj4f'.decode('idna2008'))
|
||||
домен.испытание
|
||||
|
||||
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)
|
||||
+++++++++++++++++++++++++++++++
|
||||
|
||||
As described in `RFC 5895 <https://tools.ietf.org/html/rfc5895>`_, the
|
||||
IDNA specification does not normalize input from different potential
|
||||
ways a user may input a domain name. This functionality, known as
|
||||
a “mapping”, is considered by the specification to be a local
|
||||
user-interface issue distinct from IDNA conversion functionality.
|
||||
|
||||
This library provides one such mapping that was developed by the
|
||||
Unicode Consortium. Known as `Unicode IDNA Compatibility Processing
|
||||
<https://unicode.org/reports/tr46/>`_, it provides for both a regular
|
||||
mapping for typical applications, as well as a transitional mapping to
|
||||
help migrate from older IDNA 2003 applications. Strings are
|
||||
preprocessed according to Section 4.4 “Preprocessing for IDNA2008”
|
||||
prior to the IDNA operations.
|
||||
|
||||
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
|
||||
|
||||
Transitional processing provides conversions to help transition from
|
||||
the older 2003 standard to the current standard. For example, in the
|
||||
original IDNA specification, the *LATIN SMALL LETTER SHARP S* (ß) was
|
||||
converted into two *LATIN SMALL LETTER S* (ss), whereas in the current
|
||||
IDNA specification this conversion is not performed.
|
||||
|
||||
.. code-block:: pycon
|
||||
|
||||
>>> idna.encode('Königsgäßchen', uts46=True, transitional=True)
|
||||
'xn--knigsgsschen-lcb0w'
|
||||
|
||||
Implementers should use transitional processing with caution, only in
|
||||
rare cases where conversion from legacy labels to current labels must be
|
||||
performed (i.e. IDNA implementations that pre-date 2008). For typical
|
||||
applications that just need to convert labels, transitional processing
|
||||
is unlikely to be beneficial and could produce unexpected incompatible
|
||||
results.
|
||||
|
||||
``encodings.idna`` Compatibility
|
||||
++++++++++++++++++++++++++++++++
|
||||
|
||||
Function calls from the Python built-in ``encodings.idna`` module are
|
||||
mapped to their IDNA 2008 equivalents using the ``idna.compat`` module.
|
||||
Simply substitute the ``import`` clause in your code to refer to the new
|
||||
module name.
|
||||
|
||||
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 positional context (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. These tables are
|
||||
computed 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 3.6 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.
|
||||
Removing support for older versions should be well justified in that the
|
||||
maintenance burden has become too high.
|
||||
|
||||
* **Python 2**. Python 2 is supported by version 2.x of this library.
|
||||
Use "idna<3" in your requirements file if you need this library for
|
||||
a Python 2 application. Be advised that these versions are no longer
|
||||
actively developed.
|
||||
|
||||
* **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.
