SSL/TLS support for MariaDB DB instances on Amazon RDS

Focus mode
SSL/TLS support for MariaDB DB instances on Amazon RDS - Amazon Relational Database Service

Amazon RDS creates an SSL/TLS certificate and installs the certificate on the DB instance when Amazon RDS provisions the instance. These certificates are signed by a certificate authority. The SSL/TLS certificate includes the DB instance endpoint as the Common Name (CN) for the SSL/TLS certificate to guard against spoofing attacks.

An SSL/TLS certificate created by Amazon RDS is the trusted root entity and should work in most cases, but might fail if your application doesn't accept certificate chains. If your application doesn't accept certificate chains, try using an intermediate certificate to connect to your AWS Region. For example, you must use an intermediate certificate to connect to the AWS GovCloud (US) Regions with SSL/TLS.

For information about downloading certificates, see Using SSL/TLS to encrypt a connection to a DB instance or cluster. For more information about using SSL/TLS with MySQL, see Updating applications to connect to MariaDB instances using new SSL/TLS certificates.

Amazon RDS for MariaDB supports Transport Layer Security (TLS) versions 1.3, 1.2, 1.1, and 1.0. TLS support depends on the MariaDB minor version. The following table shows the TLS support for MariaDB minor versions.
