Как мне настроить SSL в Tomcat9?

. Я попытался установить SSL на tomcat 9 на порт 8443. Однако я не знаю, поддерживает ли tomcat pem или crt формат SSL.

Я внес изменения в server.xml, но при запуске tomcat я получаю следующую ошибку в журналах catelina.out.

Ниже мой server.xmaconfiguration.

 <Connector port="8443" protocol="org.apache.coyote.http11.Http11NioProtocol"
               maxThreads="150" SSLEnabled="true">
        <SSLHostConfig>
            <Certificate certificateKeyFile="conf/privkey.key"
                         certificateFile="conf/fullchain.crt"
                         type="RSA" />
        </SSLHostConfig>
    </Connector>
