Support equipreference groups in QuicCryptoServerConfig Adds a new config setter for preferred_groups in QuicCryptoServerConfig, and updates TlsServerHandshaker to call SSL_set1_group_ids_with_flags if there are equipreference groups. This allows the server to negotiate key exchange groups with equal preference, i.e. letting the client's preference decide which group among equally preferred groups is selected. The analogous change on the client side is less meaningful, because a client's preferred_groups is always serialized on the wire as a strictly ordered list, and cannot express the concept of equipreference groups. This functionality is needed to talk to CNSA2.0 compliant clients which prefer ML-KEM-1024 over X25519-MLKEM768, while still negotiating X25519-MLKEM768 for the vast majority of clients who don't specifically prefer ML-KEM-1024.

QUICHE stands for QUIC, Http, Etc. It is Google‘s production-ready implementation of QUIC, HTTP/2, HTTP/3, and related protocols and tools. It powers Google’s servers, Chromium, Envoy, and other projects. It is actively developed and maintained.
There are two public QUICHE repositories. Either one may be used by embedders, as they are automatically kept in sync:
To embed QUICHE in your project, platform APIs need to be implemented and build files need to be created. Note that it is on the QUICHE team's roadmap to include default implementation for all platform APIs and to open-source build files. In the meanwhile, take a look at open source embedders like Chromium and Envoy to get started:
To contribute to QUICHE, follow instructions at CONTRIBUTING.md.
QUICHE is only supported on little-endian platforms.
QUICHE has binaries that can run on Linux platforms.
Follow the instructions to install Bazel.
sudo apt install libicu-dev clang lld cd <directory that will be the root of your quiche implmentation> git clone https://github.com/google/quiche.git cd quiche CC=clang bazel build -c opt //... ./bazel-bin/quiche/<target_name> <arguments>
There are several targets that can be built and then run. Full usage instructions are available using the --helpfull flag on any binary.
Usage: quic_packet_printer server|client <hex dump of packet>
Usage: crypto_message_printer_bin <hex of message>
Usage: quic_client <URL>
quic_server: listens forever on --port (default 6121) until halted via ctrl-c.
masque_client: tunnels to a URL via an identified proxy (See RFC 9298).
Usage: masque_client [options] <proxy-url> <urls>
Usage: masque_server
web_transport_test_server: a server that clients can connect to via WebTransport.
moqt_relay: a relay for the Media Over QUIC transport for publishers and subscribers can connect to.
Usage: moqt_relay
Most log messages in QUICHE use the QUICHE_DLOG macro. In standalone quiche, these all either go to stderr, or are suppressed, based on the --stderrthreshold flag.
To send INFO level log messages to a file, you would therefore invoke
<binary> <args> > <logfile> 2>&1
Use the --helpfull flag for more.
