|
|
|

quic-go is an implementation of the QUIC protocol ([RFC 9000](https://datatracker.ietf.org/doc/html/rfc9000), [RFC 9001](https://datatracker.ietf.org/doc/html/rfc9001), [RFC 9002](https://datatracker.ietf.org/doc/html/rfc9002)) in Go. It has support for HTTP/3 ([RFC 9114](https://datatracker.ietf.org/doc/html/rfc9114)), including QPACK ([RFC 9204](https://datatracker.ietf.org/doc/html/rfc9204)) and HTTP Datagrams ([RFC 9297](https://datatracker.ietf.org/doc/html/rfc9297)).
|
|
|
|
In addition to these base RFCs, it also implements the following RFCs:
|
|
|
|
* Unreliable Datagram Extension ([RFC 9221](https://datatracker.ietf.org/doc/html/rfc9221))
|
|
* Datagram Packetization Layer Path MTU Discovery (DPLPMTUD, [RFC 8899](https://datatracker.ietf.org/doc/html/rfc8899))
|
|
* QUIC Version 2 ([RFC 9369](https://datatracker.ietf.org/doc/html/rfc9369))
|
|
* QUIC Event Logging using qlog
|
|
* QUIC Stream Resets with Partial Delivery
|
|
|
|
Support for WebTransport over HTTP/3 is implemented in [webtransport-go](https://github.com/quic-go/webtransport-go).

## FIPS 140-3
|
|
|
|
Starting with v0.60, quic-go supports use in FIPS 140-3 environments when built with Go 1.26 or newer, using Go standard library cryptography for the QUIC code paths relevant in FIPS mode.
