generate self signed certificate with keytool
To generate a self-signed SSL certificate using the keytool command on Windows, Mac, or Linux:

keytool -genkey -keyalg RSA -alias tomcat -keystore selfsigned.jks -validity <days> -keysize 2048
Where <days> indicate the number of days for which the certificate will be valid.
