qh3 is a maintained fork of the awesome aioquic library.
Important changes/improvements are:
- Made abi3 compatible, no need to build the wheel all over again on each interpreter version.
- Only one dependency left! Cryptography will remain as long as Python does not ship with proper QUIC implementation.
- Mitigated deprecated match_hostname.
- Mimic load_default_certs SSL context from native Python.
- Remove the need for OpenSSL development headers.
- Many, many more pre-built wheel for your convenience! Including PyPy 3.8 and 3.9 and musl linux distributions.
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 standardised in RFC 9000 and HTTP/3 in RFC 9114.
qh3 is regularly tested for interoperability against other
QUIC implementations.
To learn more about qh3 please read the documentation.
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.
- 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
aioquic requires Python 3.7 or greater.
qh3 comes with a number of examples illustrating various QUIC use-cases.
