Use the keytool utility to create a keystore file that contains a private key and a self-signed certificate that holds a public key.
Note
To replace an expired self-signed certificate, delete the existing keystore file, follow the procedure in this topic to create a new self-signed certificate, and then configure SSL on the Tomcat server. However, before you replace an expired self-signed certificate, you must backup your old keystore and server.xml files.
