Old SSL with modern browsers, nginx and podman

---

Problem: An old software only supports SSL and not TLS. Modern browsers do not include SSL support anymore.

Solution: nginx proxy in podman.

While you could try different browsers, or old operating systems, this is neater and faster, safer, etc.

nginx.conf

events {
    worker_connections 1024;
}

http {
    server {
        listen 80;
        server_name localhost;

        location / {
            proxy_pass https://10.10.10.10;
            proxy_ssl_verify off;
            proxy_ssl_protocols SSLv3 TLSv1 TLSv1.1 TLSv1.2;
            proxy_ssl_ciphers ALL:@SECLEVEL=0;
            proxy_set_header Host $host;
            proxy_set_header X-Real-IP $remote_addr;
            proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        }
    }
}

podman run -it --rm --replace \
  --name nginx-proxy \
  -p 127.0.0.1:8080:80 \
  -v ./nginx.conf:/etc/nginx/nginx.conf:ro,Z \
  docker.io/library/nginx:alpine
