Problem

Currently, Dify's Redis connection only supports basic SSL/TLS encryption but lacks comprehensive certificate-based authentication options. This limits deployment in high-security environments where mutual TLS authentication is required.

Current Limitations

• No support for client certificate authentication
• Limited SSL certificate verification options
• Missing configuration for CA certificates
• Hardcoded SSL parameters without flexibility

Expected Behavior

The application should support:

• Different SSL certificate verification modes (none, optional, required)
• Client certificate authentication with cert/key files
• Custom CA certificate validation
• Configurable SSL parameters via environment variables

Use Cases

• Enterprise deployments requiring mutual TLS authentication
• Cloud Redis services with certificate-based authentication
• Compliance with security standards requiring encrypted data in transit
• Multi-tenant environments with strict isolation requirements
