Signal TLS Proxy

To run a Signal TLS proxy, you will need a host that has ports 80 and 443 available and a domain name that points to that host.

1. Install docker and docker-compose (https://docs.docker.com/engine/install/)
2. Ensure your current user has access to docker (adduser $USER docker)
3. Clone this repository
4. cd ./Signal-TLS-Proxy
5. docker compose build
6. docker volume create --name=caddy_data
7. sed -i 's/sub.example.com/sub.my-domain.com/g' config/caddy.json
8. docker compose up --detach

Additionally, if you'd like to harden your server against memory corruption vulnerabilities, run the following commands. This will install hardened_malloc on your server and add it to your path automatically.

1. chmod +x ./harden.sh
2. ./harden.sh

Your proxy is now running! You can share this with the URL https://signal.tube/#<your_host_name>

Updating from a previous version

If you've previously run a proxy, please update to the most recent version by pulling the most recent changes from main, then restarting your Docker containers:

git pull
docker compose down
docker compose up --detach
