è possibile per tezos-node RPC autenticare i client con SSL?

Attualmentenon è supportato.Puoi utilizzare unproxynginxperproteggerlo con Autenticazione dibase HTTP con la seguente configurazione che utilizza una connessione https sullaporta standard:

 server {
  listen 443 ssl;
  server_name tezosz-rpc.yourdomain.com;
  include letsencrypt_ssl.conf;
  ssl_certificate /fullchain.cer;
  ssl_certificate_key /tezosz-rpc.yourdomain.com.key;
  ssl_trusted_certificate /tezosz-rpc.yourdomain.com/ca.cer;
  auth_basic              "Restricted Access for tezos RPC interface over https";
  auth_basic_user_file    /usr/local/etc/nginx/htpasswd;
  location / {
      proxy_set_header Host $host;
      proxy_set_header X-Real-IP $remote_addr;
      proxy_set_header X-Forwarded-For $remote_addr;
      proxy_pass http://192.168.X.Y:8732;
  }
}
 

This is currently not supported. You can use an nginx proxy to secure it with HTTP Basic Authentication with the following configuration that uses a https connection on standard port:

server {
  listen 443 ssl;
  server_name tezosz-rpc.yourdomain.com;
  include letsencrypt_ssl.conf;
  ssl_certificate /fullchain.cer;
  ssl_certificate_key /tezosz-rpc.yourdomain.com.key;
  ssl_trusted_certificate /tezosz-rpc.yourdomain.com/ca.cer;
  auth_basic              "Restricted Access for tezos RPC interface over https";
  auth_basic_user_file    /usr/local/etc/nginx/htpasswd;
  location / {
      proxy_set_header Host $host;
      proxy_set_header X-Real-IP $remote_addr;
      proxy_set_header X-Forwarded-For $remote_addr;
      proxy_pass http://192.168.X.Y:8732;
  }
}
