This module was relevant before the standard library ``ssl`` module supported SNI, but now that we've dropped support for Python 2.7 all relevant Python versions support SNI so **this module is no longer recommended**. This needs the following packages installed: * `pyOpenSSL`_ (tested with 19.0.0) * `cryptography`_ (minimum 2.3, from pyopenssl) * `idna`_ (minimum 2.1, from cryptography) However, pyOpenSSL depends on cryptography, so while we use all three directly here we end up having relatively few packages required. You can install them with the following command: .. code-block:: bash $ python -m pip install pyopenssl cryptography idna To activate certificate checking, call :func:`~urllib3.contrib.pyopenssl.inject_into_urllib3` from your Python code before you begin making HTTP requests. This can be done in a ``sitecustomize`` module, or at any other time before your application begins using ``urllib3``, like this: .. code-block:: python try: import urllib3.contrib.pyopenssl urllib3.contrib.pyopenssl.inject_into_urllib3() except ImportError: pass .. _pyopenssl: https://www.pyopenssl.org .. _cryptography: https://cryptography.io .. _idna: https://github.com/kjd/idna � )� annotationsN)�x509)�UnsupportedExtensionc @ s e Zd ZdS )r N)�__name__� __module__� __qualname__� r r �M/opt/saltstack/salt/lib/python3.10/site-packages/urllib3/contrib/pyopenssl.pyr 2 s r )�BytesIO)�socket� )�util��X509�inject_into_urllib3�extract_from_urllib3zdict[int, int]�_openssl_versions�PROTOCOL_TLSv1_1�TLSv1_1_METHOD�PROTOCOL_TLSv1_2�TLSv1_2_METHODc C s i | ]\}}||�qS r r )�.0�k�vr r r � <dictcomp>X s r � OP_NO_SSLv2� OP_NO_SSLv3�int�_OP_NO_SSLv2_OR_SSLv3� OP_NO_TLSv1� _OP_NO_TLSv1� OP_NO_TLSv1_1�_OP_NO_TLSv1_1� OP_NO_TLSv1_2�_OP_NO_TLSv1_2� OP_NO_TLSv1_3�_OP_NO_TLSv1_3� _openssl_to_ssl_minimum_version� _openssl_to_ssl_maximum_versioni @ �return�Nonec C s& t � tt_ttj_dt_dtj_dS )z7Monkey-patch urllib3 with PyOpenSSL-backed SSL-support.TN)�_validate_dependencies_met�PyOpenSSLContextr � SSLContext�ssl_� IS_PYOPENSSLr r r r r � s c C s t t_t tj_dt_dtj_dS )z4Undo monkey-patching by :func:`inject_into_urllib3`.FN)�orig_util_SSLContextr r- r. r/ r r r r r � s c C sR ddl m} t| dd�du rtd��ddlm} |� }t|dd�du r'td��dS ) z{ Verifies that PyOpenSSL's package-level dependencies have been met.

Cryptography produces a dNSName as a unicode string that was idna-decoded from ASCII bytes. We need to idna-encode that string to get it back, and then on Python 3 we also need to convert to unicode via UTF-8 (the stdlib uses PyUnicode_FromStringAndSize on it, which decodes via UTF-8). If the name cannot be idna-encoded then we return None signalling that the name given should be skipped. r6 r7 r) � bytes | Nonec S sl ddl }z%dD ] }| �|�r#| t|�d� } |�d�|�| � W S q|�| �W S |jjy5 Y dS w )z� Borrowed wholesale from the Python Cryptography Project.
