✅ Permission selection with checkboxes  
✅ Expiration date options  
✅ Usage statistics display  
✅ One-time key display alert  
✅ Copy to clipboard functionality  

### Security Features
✅ SHA256 hashing (keys never stored plaintext)  
✅ Secure generation (crypto.randomBytes)  
✅ Granular permissions (5 scopes)  
✅ Expiration dates (7d/30d/3m/1m)  
✅ Revocation support (disable without deletion)  
✅ Usage tracking for audit logs  
✅ Header authentication (Bearer + X-API-Key)

## ✨ Features Implemented

### 1. **API Key Management**
- Generate 64-character hex keys
- Display only once after creation
- Show preview (e.g., abc12345...xyz9)
- Friendly name for each key
- Metadata (created, last used, expires)

### 2. **Permissions System**
- **read:posts** — Access post data
- **write:posts** — Create/update posts
- **read:analytics** — View analytics
- **read:settings** — Access settings
- **read:webhooks** — View webhook logs

### 3. **Key Lifecycle**
- Create with name, permissions, optional expiry
- Use via Authorization: Bearer or X-API-Key header
- Revoke to disable (keep for audit trail)
- Delete to permanently remove
- Automatic expiration after set date

### 4. **Usage Tracking**
- Log every API request
- Track method, endpoint, status
- Record IP address and user agent
- Get statistics per key
- Query usage logs with filtering

### 5. **Developer Experience**
- UI to manage all keys
- Copy-to-clipboard for created keys
- Revoke without deletion (audit trail)
- Permission checkboxes
- Expiration pre-set options
- Usage statistics per key

## 📋 API Endpoints

| Endpoint | Method | Purpose |
|----------|--------|---------|
| `/api/api-keys` | GET | List all keys |
| `/api/api-keys` | POST | Create new key |
| `/api/api-keys/:id/revoke` | POST | Revoke key |
| `/api/api-keys/:id` | DELETE | Delete key |
| `/api/api-keys/:id/permissions` | PUT | Update permissions |
| `/api/api-keys/:id/stats` | GET | Key statistics |
| `/api/api-keys/logs` | GET | Usage logs |
| `/api/api-keys/permissions` | GET | Available permissions |

---

## 📊 Code Statistics

| Metric | Count |
|--------|-------|
| Backend Lines | 600+ |
| Frontend Lines | 300+ |
| API Endpoints | 8 |
| Components | 1 |
| Middleware | 1 |
| Services | 1 |

## 🔐 Security Implementation

✅ **Key Generation**
- Uses `crypto.randomBytes(32)` for 256-bit entropy
- Converted to hex (64 characters)
- Never transmitted or logged

✅ **Key Storage**
- SHA256 hashes stored in database
- Original key shown only once
- Preview for easy identification

✅ **Key Usage**
- Hash incoming key
- Compare with stored hash
- Verify expiration date
- Check revocation status
- Validate permissions
- Log all requests

✅ **Authentication Methods**
- `Authorization: Bearer <key>`
- `X-API-Key: <key>`
- Both supported simultaneously

## 🚀 Usage Example

### Create API Key
```bash
curl -X POST https://api.haznox.com/api/api-keys \
  -H "Authorization: Bearer USER_JWT_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{
    "name": "Production API",
    "permissions": ["read:posts", "read:analytics"],
    "expires_in": "30d"
  }'
```

### Use API Key
```bash
# Method 1: Bearer token
curl -H "Authorization: Bearer abc123...xyz789" \
  https://api.haznox.com/api/posts

# Method 2: X-API-Key header
curl -H "X-API-Key: abc123...xyz789" \
  https://api.haznox.com/api/posts
```

### Revoke Key
```bash
curl -X POST https://api.haznox.com/api/api-keys/key-id/revoke \
  -H "Authorization: Bearer USER_JWT_TOKEN"
```

## 🧪 Testing Checklist

### Manual E2E Tests
- [ ] Create API key with permissions
  1. Go to Developer Settings
  2. Click "Create Key"
  3. Fill name, select permissions, set expiry
  4. Click "Create API Key"
  5. See one-time display of full key
  6. Verify preview matches

- [ ] Use API key to authenticate
  1. Create key with read:posts
  2. Call GET /api/posts with Bearer token
  3. Should work
  4. Try without key → 401 error

- [ ] Permission enforcement
  1. Create key with only read:posts
  2. Try calling write:posts endpoint
  3. Should get 403 (insufficient permissions)

- [ ] Key revocation
  1. Create and use key (verify works)
  2. Revoke key
  3. Try using key again
  4. Should get 401 (revoked)

- [ ] Expiration
  1. Create key that expired yesterday
  2. Try using key
  3. Should get 401 (expired)

- [ ] Usage logging
  1. Create key
  2. Make several API calls
  3. View stats → should show requests
