Enable internal and external Cassandra encryption by creating Java keystores and truststores along with SSL certificates.

Create the keystore.shared file by running the following command: keytool -genkey -keyalg RSA -alias shared -validity 36500 -keystore keystore.shared -storepass cassandra -keypass cassandra -dname "CN=None, OU=None, O=None, L=None, C=None" where cassandra is the password the certificate.
Export the SSL certificate from the keystore.shared file to the shared.cer file by running the following command: keytool -export -alias shared -file shared.cer -keystore keystore.shared -storepass cassandra where cassandra is the password the certificate.
Create the truststore.shared file and import the SSL certificate to that file by running the following command: keytool -importcert -v -trustcacerts -noprompt -alias shared -file shared.cer -keystore truststore.shared -storepass cassandra where cassandra is the password the certificate.
