goldy is lightweight DTLS proxy which allows adding DTLS encryption (using mbed TLS) to UDP servers without modifying their code.
To build goldy from source:
git clone https://github.com/ibm-security-innovation/goldy.git
cd goldy
make deps
make
Use make V=1 for a verbose build output and make DEBUG=1 to enable debug
info (-g3).
Usage: goldy [-hvd] [-g log_level] [-t seconds] -l listen_host:port
-b backend_host:port -c cert_pem_file -k private_key_pem_file
Options:
-h, --help this help
-v, --version show version and exit
-d, --daemonize run as a daemon
-g, --log=LEVEL log level DEBUG/INFO/ERROR
-t, --timeout=SECONDS Session timeout (seconds)
-l, --listen=ADDR:PORT listen for incoming DTLS on addr and UDP port
-b, --backend=ADDR:PORT proxy UDP traffic to addr and port
-c, --cert=FILE TLS certificate PEM filename
-k, --key=FILE TLS private key PEM filename
The following command compiles the test client and server and then runs the full-cycle test suite:
make test
To build the Docker image:
docker build . -t goldy:latest
The Docker image has an entrypoint script which makes easy to pass the certificate and key, without requiring the use of a volume. To do so, run:
docker run -e LISTEN=:::5683 \
-e BACKEND=<backend host:port> \
-e KEY=<base64> \
-e CERT=<base64> \
-p 5683:5683 \
