Enabling or Disabling SSL

Secure Socket Layer (SSL) is an encryption-based Internet security protocol for establishing an encrypted link between a server and a client. It provides privacy, authentication, and integrity to Internet communications.

Authenticates users and servers, ensuring that data is sent to the correct clients and servers.
Encrypts data to prevent it from being intercepted during transfer.
Ensures data integrity during transmission.

After SSL is enabled, you can establish an encrypted connection between your client and the instance you want to access to improve data security.

Precautions

Enabling or disabling SSL will cause instances to restart. Exercise caution when performing this operation.

If SSL is enabled, you can connect to a database using SSL, which is more secure.

Currently, insecure encryption algorithms are disabled. The following table lists the supported TLS versions and cipher suites.

Version	TLS Version	Cipher Suites
3.4	TLS 1.2	AES256-GCM-SHA384 AES128-GCM-SHA256
4.0	TLS 1.2	DHE-RSA-AES256-GCM-SHA384 DHE-RSA-AES128-GCM-SHA256

The server where the client is located must support the corresponding TLS version and encryption algorithm suite. Otherwise, the connection fails.

If SSL is disabled, you can connect to a database using an unencrypted connection.

Enabling SSL
