# Phase 1: Security + Testing
|
|
|
|
> Date: 2026-03-21
|
|
> Status: Complete
|
|
|
|
## Overview
|
|
|
|
This phase establishes the security foundation and testing framework for the ZCLAW architecture optimization project. It implements encrypted credential storage and enforces secure WebSocket connections.
|
|
|
|
## Changes
|
|
|
|
### Security Enhancements
|
|
|
|
#### 1. Encrypted localStorage Fallback (`secure-storage.ts`)
|
|
|
|
- **Issue**: Credentials were stored in plaintext in localStorage when OS keyring was unavailable
|
|
- **Solution**: Implemented AES-GCM encryption for localStorage fallback
|
|
- **Details**:
|
|
- Added `crypto-utils.ts` with encryption/decryption functions
|
|
- Uses PBKDF2 (100,000 iterations) for key derivation
|
|
- Uses AES-GCM (256-bit) for encryption
|
|
- Unique IV per encryption operation
|
|
- Backward compatible with existing unencrypted data
|
|
|
|
#### 2. WSS Enforcement (`gateway-client.ts`)
|
|
|
|
- **Issue**: Non-localhost connections could use insecure `ws://` protocol
|
|
- **Solution**: Block non-localhost connections that don't use WSS
|
|
- **Details**:
|
|
- Added `SecurityError` class for clear error handling
|
|
- Added `validateWebSocketSecurity()` function
|
|
- Throws error for `ws://` connections to non-localhost hosts
|
|
- Allows `ws://` for localhost (development convenience)
|
|
- Allows `wss://` for any host
|
|
|
|
### Testing Infrastructure
|
|
|
|
#### 1. Vitest Framework Setup
|
|
|
|
- Installed Vitest 2.1.8 with jsdom environment
|
|
- Added @testing-library/react for component testing
|
|
- Added @testing-library/jest-dom for DOM matchers
|
|
- Configured coverage thresholds (60% initial target)
|
|
|
|
#### 2. Test Files Created
|
|
|
|
| File | Tests | Coverage |
|
|
|------|-------|----------|
|
|
| `crypto-utils.test.ts` | 10 | arrayToBase64, base64ToArray, encrypt, decrypt, deriveKey, generateMasterKey |
|
|
| `secure-storage.test.ts` | 11 | Encryption fallback, backward compatibility, special characters |
|
|
| `gateway-security.test.ts` | 13 | isLocalhost, WSS enforcement, SecurityError |
|
|
| `chatStore.test.ts` | 39 | Messages, conversations, agents, streaming |
|
|
|
|
## Files Changed
|
|
|
|
### New Files
|
|
|
|
```
|
|
desktop/
|
|
├── src/lib/crypto-utils.ts # AES-GCM encryption utilities
|
|
├── tests/lib/crypto-utils.test.ts # Encryption tests
|
|
├── tests/lib/secure-storage.test.ts # Secure storage tests
|
|
├── tests/lib/gateway-security.test.ts # WSS security tests
|
|
├── tests/setup.ts # Vitest setup with mocks
|
|
└── vitest.config.ts # Vitest configuration
|

```
|
|

|
### Modified Files
|
|
|
|
```
|
|
desktop/
|
|
├── src/lib/secure-storage.ts # Added encryption fallback
|
|
├── src/lib/gateway-client.ts # Added WSS enforcement
|
|
└── package.json # Added test dependencies
|
|
```
|
|
|
|
## Migration Notes
|
|
|
|
- **Automatic Migration**: Existing unencrypted localStorage data will be automatically migrated on first read
|
|
- **No Manual Intervention**: The encryption/decryption is transparent to users
|
|
- **Key Generation**: A master key is automatically generated and stored in localStorage
|
|
|
|
## Breaking Changes
|
|
|
|
### WSS Required for Remote Connections
|
|
|
|
- `ws://` protocol is no longer allowed for non-localhost connections
|
|
- **Impact**: Users connecting to remote servers must use `wss://`
|
|
- **Migration**: Update gateway URLs to use `wss://` protocol
|
|
|
|
```javascript
|
|
// Before (now throws SecurityError)
|
|
const client = new GatewayClient('ws://example.com:4200/ws');
|
|
|
|
// After (required)
|
|
const client = new GatewayClient('wss://example.com:4200/ws');
|
|
|
|
// Localhost still works with ws://
|
|
const client = new GatewayClient('ws://localhost:4200/ws'); // OK
|
|
```
|
|
|
|
## Test Results
|
|
|
|
```
|
|
Test Files 4 passed (4)
|
|
Tests 73 passed (73)
|
|
|
|
New modules coverage:
|
|
- crypto-utils.ts: 100%
|
|
- secure-storage.ts: 95%+
|
|
- gateway-security: 100%
|
|
- chatStore.ts: 80%+
|
|
```
|
|
|
|
## Security Verification
|
|
|
|
- [x] localStorage credentials encrypted (AES-GCM)
|
|
- [x] Non-localhost connections require WSS
|
|
- [x] Encryption keys not exposed in logs
|
|
- [x] Backward compatible with unencrypted data
|
|
- [x] Unique IV per encryption operation
|
|
|
|
## Next Steps (Phase 2)
|
|
|
|
- Domain reorganization
|
|
- Migrate Chat Store to Valtio
|
|
- Migrate Hands Store + XState
|
|
- Enhance Intelligence caching
|
|
- Extract shared modules
