Status : core feature, unit tested and maintained.
When you are in SSL mode (client or server), you can use all the parameters using by node for SSL / TLS, prefixed by ssl_.
You have to give path for certificate and key params, node-logstash will load them before initializing SSL / TLS stack.
For example, for a HTTPS server : ssl=true&ssl_cert=/path/to/cert&ssl_key=/path/to/key
For using a Certificate authority, add &ssl_ca=/path/to/ca.
For changing SSL ciphers, add ssl_ciphers=AES128-GCM-SHA256.
To use a client certificate, add ssl_cert=/client.cer&ssl_key=/client.key&ssl_ca=/tmp/ca.key.
To ignore ssl errors, add ``ssl_rejectUnauthorized=false`.
