This is a ngtcp2 client docker image building on quictls and OQS provider, which allows ngtcp2 to negotiate quantum-safe keys in TLS 1.3.
Assuming Docker is installed the following command
docker run --network ngtcp2-test --name ngtcp2client -it openquantumsafe/ngtcp2-client sh
will run the container for the quantum-safe crypto (QSC) protected ngtcp2 client on the docker network called ngtcp2-test (assuming it has already been created. If not, run docker network create ngtcp2-test ).
To interact with the ngtcp2 server, run
qtlsclient <address> <port> [<URI>][--groups <groups>]
For example, qtlsclient ngtcp2server 6000 https://ngtcp2server --groups kyber512
By default the ngtcp2 client supports X25519, P-256, P-384 and P-521 for key exchange but any plain or hybrid QSC (Quantum-Safe Cryptography) algorithm can be selected. See list of supported key exchange algorithms here.
If multiple algorithms are selected, they are separated with colons.
For example, --groups=kyber512:p256_bikel1
For more options, run qtlsclient --help
