v.25.8New Feature
Force secure connection for mysql_port and postgresql_port
Force secure connection for mysql_port and postgresql_port. #82962 (tiandiwonder).
Why it matters
This feature enhances security by enforcing encrypted connections on MySQL and PostgreSQL protocol ports of ClickHouse, preventing unencrypted data transmission and protecting sensitive information during client-server communication.How to use it
When this feature is enabled, ClickHouse requires all client connections overmysql_port and postgresql_port to use secure protocols (e.g., SSL/TLS). Users should configure their clients to connect securely. The enforcement is automatic on these ports with no additional configuration needed unless specific certificate setup is required for SSL/TLS.
