omniCoder77 opened a new pull request, #4499: URL: https://github.com/apache/cassandra/pull/4499
Fixes: [CASSANDRA-21007](https://issues.apache.org/jira/browse/CASSANDRA-21007) ## Problem `cassandra-stress` can not connect to tls 1.3 servers with the current default cipher suites (TLS_RSA_WITH_AES_128_CBC_SHA and TLS_RSA_WITH_AES_256_CBC_SHA) because they don't have perfect forward secrecy, which tls 1.3 needs. ## What i changed I updated the default cipher suites in the ssl-ciphers option to use modern ones that support PFS: Old ciphers: - `TLS_RSA_WITH_AES_128_CBC_SHA,TLS_RSA_WITH_AES_256_CBC_SHA` New ciphers: - `TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384,TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256` ## Why This Helps * Fixes the tls 1.3 connection issue * Adds perfect forward secrecy using ecdhe * Switches from cbc to gcm which is more secure * Still works with tls 1.2 servers This is my first open source contribution, kindly let me know if i need to change anything or if there is any issue with my approach. -- This is an automated message from the Apache Git Service.
