[teiid-issues] [JBoss JIRA] (TEIID-4663) Support a more secure block mode for client/server encryption

Support a more secure block mode for client/server encryption ------------------------------------------------------------- Key: TEIID-4663 URL: https://issues.jboss.org/browse/TEIID-4663 Project: Teiid Issue Type: Quality Risk Components: JDBC Driver, Server Reporter: Steven Hawkins Assignee: Steven Hawkins Fix For: 9.0.6, 9.1.2, 9.2, 8.12.x-6.4, 8.12.11.6_3 ECB is the current default for the socket transport encryption of secure messages. While this is relatively ok for small messages as we also have a message key acting as a CTR counter to some of the blocks, it does not provide strong security - especially for large data volume scenarios, such as when using larger login payloads or the secure requests option. We should default instead to CBC with an explicit initialization vector.
