Enable JCE Unlimited
DataStax recommends enabling Java Cryptography Extension (JCE) Unlimited to ensure support for all encryption algorithms.
In JDK 8u151 and later, JCE Unlimited is enabled by default.
If you disabled JCE Unlimited, you can reenable it with the following Security property in the java.security file:
crypto.policy=unlimitedWhen set in java.security, or when declared dynamically using the Security.setProperty() call before the JCE framework has been initialized, the unlimited setting is used by the JDK.
Some of the cipher suites in the default set of server_encryption_options in cassandra.yaml are included only in the Java Cryptography Extension (JCE) Unlimited Strength Jurisdiction Policy Files.
