Obtener certificado del servidor

Mediante el siguiente comando obtienes el certificado del servidor. De esta manera puedes añadir el certificado, el que lo firma (que debe ir tambien en el certificado), en el fichero cacerts de java.

openssl s_client -showcerts -connect server:port > ./certificadoServidor.cer </dev/null
Obtener certificado del servidor

Crear KeyStores para cliente y servidor

Sigue los siguientes pasos para obtener un keystore para el cliente y el servidor. La contraseña comun a todos los certificados y keysotre sera: 18091980
