By default, SSL is disabled for Redis 6.0 basic edition instances. To enable it, see SSL Settings.
When SSL encrypted transmission is enabled, Redis will generate a unique service certificate for each instance. When connecting to an instance, clients can use the CA root certificates downloaded from the console to authenticate the instance server and encrypt data during transmission.
Redis versions 2.8, 4.0 and 5.0 only support plaintext transmission. They do not support SSL encrypted transmission.
