Latest Encryption in Transit Developments for YSQL

YugabyteDB, a database that stores critical user data, emphasizes the importance of encryption in transit for secure client-to-server communication. Recent developments in YugabyteDB 2.25 introduce new options for encryption in transit, particularly focusing on YSQL client-to-server interactions. The update includes a major upgrade to PostgreSQL 15, allowing enhanced client certificate authentication and verification methods. These methods aim to prevent unauthorized data snooping, authenticate servers, and verify clients using mutual TLS (mTLS). YugabyteDB maintains its PostgreSQL compatibility, ensuring users benefit from PostgreSQL's encryption options while offering the scalability and resilience of a cloud-native database. The platform supports custom certificate authorities and seamless rotation of server and CA certificates, making it suitable for applications requiring high security and availability.
