In #14204, support for NPN was added. Subsequently, NPN has been superseded by ALPN in the IETF, and support for it is coming in OpenSSL 1.0.2. http://tools.ietf.org/html/draft-ietf-tls-applayerprotoneg http://rt.openssl.org/Ticket/Display.html?id=3073 http://git.openssl.org/gitweb/?p=openssl.git;a=blob;f=NEWS |

HTTP/2 requires ALPN, BTW. |

Updating to mention a concern with ALPN implementation. HTTP/2 requires that a cipher with AEAD be negotiated. However, it also allows for offering a wider range of cipher suites: if an AEAD cipher is not present, this will allow fallback to HTTP/1.1. There's some interplay between ALPN and cipher selection here. We'll want to ensure that either ALPN negotiation can inform cipher selection or vice-versa, or writing a Python HTTP/2 server will get tricky fast. |

Updating to note that OpenSSL 1.0.2 has been released[0], which makes this feature supportable. [0]: https://mta.openssl.org/pipermail/openssl-announce/2015-January/000019.html |

Well, sure, but that means you plan to make it available in 3.4.3? Why is that? |

_ssl cannot be compiled with LibreSSL anymore (on OpenBSD 5.5) because of ALPN: see issue #23329. |
