- Added CFG_ALLOWED_KEY struct with binary key storage (64 bytes) for fast memcmp comparison - Implemented parsing of [allowed_keys] section with allow_all flag and per-key entries - Added key validation in etcp_connections.c server handler (errorcode=8 for rejected keys) - Default behavior: deny all if [allowed_keys] section is missing or allow_all=0 with no keys - Added proper memory cleanup and debug logging for allowed_keys configuration - Updated all test configs to include [allowed_keys] allow_all=1 for backward compatibility
