What is qh3?

qh3 is a maintained fork of the aioquic library.

It is lighter, faster, and more adapted to a broader audience as this package has no external dependency and does not rely on mainstream OpenSSL.

While it is a compatible fork, it is not a drop-in replacement since the first major. See the CHANGELOG for details.

qh3 is a library for the QUIC network protocol in Python. It features a minimal TLS 1.3 implementation, a QUIC stack, and an HTTP/3 stack.

QUIC was standardized in RFC 9000 and HTTP/3 in RFC 9114. qh3 follow the standardized version of QUIC and HTTP/3.

QUIC stack conforming with RFC 9000 (QUIC v1) and RFC 9369 (QUIC v2)

To learn more about qh3 please read the documentation.

qh3 stands for Q UIC . H TTP/ 3.

Our primary goal with this fork is mainly about the client aspect, while the server side code is maintained, we do not have enough time to add feature to it at the moment.

PR are welcomed for any improvement (server or client).

Why should I use qh3?

qh3 has been designed to be embedded into Python client and server libraries wishing to support QUIC and/or HTTP/3. The goal is to provide a common codebase for Python libraries in the hope of avoiding duplicated effort.

Both the QUIC and the HTTP/3 APIs follow the "bring your own I/O" pattern, leaving actual I/O operations to the API user. This approach has a number of advantages including making the code testable and allowing integration with different concurrency models.

This library is the lowest level you can find for handling QUIC and HTTP/3. Here are higher libraries:

Features

  • QUIC stack conforming with RFC 9000
  • HTTP/3 stack conforming with RFC 9114
  • minimal TLS 1.3 implementation conforming with RFC 8446
  • IPv4 and IPv6 support
  • connection migration and NAT rebinding
  • logging TLS traffic secrets
  • logging QUIC events in QLOG format
  • HTTP/3 server push support
  • Post-Quantum (KEM) Key-Exchange (Kyber R3 NIST)

Requirements

qh3 requires Python and PyPy 3.7 or greater.

Running the examples

qh3 comes with a number of examples illustrating various QUIC use cases.
