Hey

I think I need to implement this TODO:

github.com

dadoonet/fscrawler/blob/741746ca17afbb095ce4c706f3f845015e96022b/elasticsearch-client/src/main/java/fr/pilato/elasticsearch/crawler/fs/client/ElasticsearchClient.java#L158-L167


      
          // TODO implement this part and add elasticsearch ssl settings
          // If we have a truststore and a keystore, let's use it
          /*
          SslConfigurator sslConfig = SslConfigurator.newInstance()
                  .trustStoreFile("./truststore_client")
                  .trustStorePassword("secret-password-for-truststore")
                  .keyStoreFile("./keystore_client")
                  .keyPassword("secret-password-for-keystore");
          sslContext = sslConfig.createSSLContext();
          */

cacert is not a supported option I think.
But read this: Elasticsearch settings — FSCrawler 2.10-SNAPSHOT documentation

This might help.
