libquicr

Implementation of transport layer api based on QuicR. Please see for further details QuicR Protocol

The actual protocol implementation is covered here.

Quickstart

Cmake FetchContent

All the dependecies are now fetched via cmake and below steps should build libquicr.a

brew install openssl
export PKG_CONFIG_PATH="/opt/homebrew/opt/openssl@3/lib/pkgconfig"
git clone git@github.com:Quicr/libquicr.git
cd libquicr
git submodule update --init --recursive
mkdir build
cd build
cmake ..
make all

Build Docker Dev Image

If building docker image is the preferred option, please follow the below steps

The developer image contains picotls, picoquic and quicrq, which are required for many other builds. The container works by running it with a volume mount /ws/src to the source to be compiled. The above libraries are in the /ws/ directory, which is expected for builds.

While quicrq is included under /ws/quicrq, the container can be used to develop and compile it by mounting quicrq directory to /ws/src.

The docker container has been tested to work for both ARM (M1/Apple Silicon) and x86.

git clone git@github.com:Quicr/libquicr.git
cd libquicr

tar -c -C ../ ./quicrq ./libquicr  \
    | docker buildx build --progress=plain \
        --output type=docker \
        -f libquicr/build.Dockerfile -t quicr/libquicr:latest -

cd <libquicr directory>

rm -rf $(pwd)/build
docker run --rm \
    -v $(pwd):/ws/src \
    quicr/libquicr:latest make all

For now, it's best to run the binaries in interactive shell. The images have been built for linux. Run the image in interactive mode to access the shell prompt. From there you can access the binaries. quicrq and others are located under /ws/. For example, you can run /ws/quircq/quicrq_app binary.

docker run --rm -it \
    -v $(pwd):/ws/src \
    quicr/libquicr:latest bash

Running Examples

Running Relays/Etc.

In order to test QUIC, the server/really needs to have a certificate. The program expects the

Generate self-signed certificate for really server to test with.

cd build/cmd/really
openssl req -nodes -x509 -newkey rsa:2048 -days 365 \
    -subj "/C=US/ST=CA/L=San Jose/O=Cisco/CN=test.quicr.ctgpoc.com" \
    -keyout server-key.pem -out server-cert.pem
