SSLContext has a set_ciphers() method but no method to get the actual list of enabled ciphers. https://github.com/tiran/cpython/tree/feature/openssl_ciphers implements get_ciphers() >>> import ssl, pprint >>> ctx = ssl.SSLContext(ssl.PROTOCOL_SSLv23) >>> ctx.set_ciphers('ECDHE+AESGCM:!ECDSA') >>> pprint.pprint(ctx.get_ciphers()) [{'alg_bits': 256, 'description': 'ECDHE-RSA-AES256-GCM-SHA384 TLSv1.2 Kx=ECDH Au=RSA ' 'Enc=AESGCM(256) Mac=AEAD', 'id': 50380848, 'name': 'ECDHE-RSA-AES256-GCM-SHA384', 'protocol': 'TLSv1/SSLv3', 'strength_bits': 256}, {'alg_bits': 128, 'description': 'ECDHE-RSA-AES128-GCM-SHA256 TLSv1.2 Kx=ECDH Au=RSA ' 'Enc=AESGCM(128) Mac=AEAD', 'id': 50380847, 'name': 'ECDHE-RSA-AES128-GCM-SHA256', 'protocol': 'TLSv1/SSLv3', 'strength_bits': 128}] With OpenSSL 1.1 the dict will have more fields. Both the return value and functionality is different to https://docs.python.org/3/library/ssl.html#ssl.SSLSocket.shared_ciphers . |

What does "kea" mean? Key exchange? |

KEA stands for key exchange algorithm. |

New changeset dad4c42869f6 by Christian Heimes in branch 'default': Issue 27866: relax get_cipher() test even more. Gentoo buildbot has no ECDHE https://hg.python.org/cpython/rev/dad4c42869f6 |

I have relaxed the tests and stabilized the buildbots. Some Gentoo machines don't have ECDHE cipher suites enabled. |
