# Redis Object Cache Encryption

 * I’m configuring ElastiCache for Redis to work with my RDS instance and have enabled
   both encryption-at-rest and encryption-in-transit.
 * However, when I set transit encryption mode to “Required”, my WordPress plugin
   Redis Object Cache fails to connect to the ElastiCache cluster. I want to enforce
   encrypted TCP connections but still maintain plugin functionality.
 * Could you help identify whether this issue lies with the ElastiCache configuration
   or the plugin’s compatibility with the required encryption? Any guidance on how
   to resolve this would be appreciated.

 * Encrypted TCP connections must use the `tls://` scheme. Check the readme for 
   more 🤙
