Implemented a comprehensive secure authentication mechanism for inter-node cluster communication with the following features: 1. Global Cluster Secret (GCS) - Auto-generated cryptographically secure random secret (256-bit) - Configurable via YAML config file - Shared across all cluster nodes for authentication 2. Cluster Authentication Middleware - Validates X-Cluster-Secret and X-Node-ID headers - Applied to all cluster endpoints (/members/*, /merkle_tree/*, /kv_range) - Comprehensive logging of authentication attempts 3. Authenticated HTTP Client - Custom HTTP client with cluster auth headers - TLS support with configurable certificate verification - Protocol-aware (http/https based on TLS settings) 4. Secure Bootstrap Endpoint - New /auth/cluster-bootstrap endpoint - Protected by JWT authentication with admin scope - Allows new nodes to securely obtain cluster secret 5. Updated Cluster Communication - All gossip protocol requests include auth headers - All Merkle tree sync requests include auth headers - All data replication requests include auth headers 6. Configuration - cluster_secret: Shared secret (auto-generated if not provided) - cluster_tls_enabled: Enable TLS for inter-node communication - cluster_tls_cert_file: Path to TLS certificate - cluster_tls_key_file: Path to TLS private key - cluster_tls_skip_verify: Skip TLS verification (testing only) This implementation addresses the security vulnerability of unprotected cluster endpoints and provides a flexible, secure approach to protecting internal cluster communication while allowing for automated node bootstrapping. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
