Amazon Relational Database Service (Amazon RDS) supports SSL encryption for PostgreSQL DB instances. Using SSL, you can encrypt a PostgreSQL connection between your applications and your Amazon RDS for PostgreSQL DB instances. By default, Amazon RDS for PostgreSQL uses SSL/TLS and expects all clients to connect by using SSL/TLS encryption. Amazon RDS for PostgreSQL supports TLS versions 1.1 and 1.2.
This pattern describes how you can enable encrypted connections for an Amazon RDS for PostgreSQL DB instance. You can use the same process to enable encrypted connections for Amazon Aurora PostgreSQL-Compatible Edition.
