## Features Implemented

### List Page (`/keys`)

- **Display Columns:**
  - Reference (with key icon)
  - Name (human-readable)
  - Scope (color-coded badge)
  - Owner (identifier or "—")
  - Encrypted status (Yes/No with icons)
  - Created timestamp
  - Actions (Edit/Delete buttons)

- **Search & Filtering:**

  - Edit button per row (opens modal)
  - Delete button per row (with confirmation)

- **Pagination:**
  - 20 items per page
  - Previous/Next navigation
  - Page indicator

### Create Modal

- **Required Fields:**
  - Reference (unique identifier with validation)
  - Name (human-readable description)
  - Value (format-dependent validation)
  - Scope (owner type)

- **Value Format Options:**
  - **Text:** Plain text, can be encrypted
  - **JSON:** Validates JSON syntax, can be encrypted
  - **YAML:** Basic validation, can be encrypted
  - **Number:** Validates numeric, **cannot be encrypted**
  - **Integer:** Validates integer, **cannot be encrypted**
  - **Boolean:** Validates true/false, **cannot be encrypted**

- **Encryption Rules:**
  - Text, JSON, YAML formats: Encryption checkbox enabled
  - Number, Integer, Boolean formats: Encryption checkbox disabled
  - Automatic encryption toggle disable for non-encryptable formats
  - Clear UI indication of encryption capability per format

- **Scope Configuration:**
  - System: Global scope, no owner required
  - User (Identity): Optional owner identifier
  - Pack: Optional pack reference
  - Action: Optional action reference
  - Sensor: Optional sensor reference

- **Validation:**
  - Reference format: alphanumeric, underscores, hyphens, dots only
  - Value format-specific validation
  - Required field checks
  - Error messages displayed in modal

### Edit Modal

- **Features:**
  - Load existing key data
  - Display read-only metadata (reference, scope, owner)
  - Edit name and value
  - Show/Hide value toggle (Eye/EyeOff icons)
  - Encryption toggle
  - Warning when changing encryption status
  - Only sends changed fields to API

- **Security:**
  - Value masked by default (can be toggled)
  - Clear indication of current encryption status
  - Warnings for encryption changes

## Technical Implementation

### API Integration

Uses `SecretsService` from generated API client:
- `listKeys({ page, perPage, ownerType, owner })` - List with pagination
- `getKey({ ref })` - Get single key with decrypted value
- `createKey({ requestBody })` - Create new key
- `updateKey({ ref, requestBody })` - Update existing key
- `deleteKey({ ref })` - Delete key

### State Management

- React Query for server state and caching
- Local state for UI (search, filters, modals)
- Optimistic updates with cache invalidation
- Proper loading and error states

### Scope (Owner Type) Badges

Color-coded badges for quick identification:
- **System**: Purple (bg-purple-100, text-purple-800)
- **User (Identity)**: Blue (bg-blue-100, text-blue-800)
- **Pack**: Green (bg-green-100, text-green-800)
- **Action**: Yellow (bg-yellow-100, text-yellow-800)
- **Sensor**: Indigo (bg-indigo-100, text-indigo-800)

### Encryption Indicators

- **Encrypted**: EyeOff icon (green) + "Yes" text
- **Not Encrypted**: Eye icon (gray) + "No" text

### Format Validation Logic

```typescript
export type KeyFormat = "text" | "json" | "yaml" | "number" | "int" | "bool";

// Encryptable formats
const canEncrypt = format === "text" || format === "json" || format === "yaml";

// Validation examples:
- JSON: JSON.parse(value)
- Number/Int: Number(value), isNaN check
- Boolean: value.toLowerCase() === "true" || "false"
```

## Design Patterns

1. **Consistent Modal Pattern:**
   - Fixed overlay with centered modal
   - Header with title and close button
   - Form with validation
   - Footer with Cancel and Submit buttons
   - Loading states during mutation

2. **Format-Aware UI:**
   - Dynamic textarea rows based on format
   - Placeholder text matches expected format
   - Validation errors specific to format
   - Auto-disable encryption for incompatible formats

3. **Security-First Approach:**
   - Encryption enabled by default for encryptable formats
   - Values masked in edit modal
   - Confirmation dialogs for destructive actions
   - Clear warnings when changing encryption

4. **Responsive Design:**
   - Grid layout for filters
   - Responsive table with horizontal scroll
   - Mobile-friendly pagination
   - Consistent with other pages (Events, Enforcements)

## User Flow Examples

### Creating a JSON Secret

1. Click "Create Key" button
2. Enter reference: `api_config`
3. Enter name: "API Configuration"
4. Select format: **JSON** (encryption checkbox enabled)
5. Enter value: `{"url": "https://api.example.com", "timeout": 30}`
6. Check "Encrypt value" (recommended)
7. Select scope: System
8. Click "Create Key"
9. ✅ Key created with encrypted JSON value

### Creating a Number Configuration

1. Click "Create Key" button
2. Enter reference: `max_retries`
3. Enter name: "Maximum Retry Attempts"
4. Select format: **Number** (encryption checkbox disabled)
5. Enter value: `3`
6. Note: Cannot encrypt (checkbox disabled and grayed out)
7. Select scope: System
8. Click "Create Key"
9. ✅ Key created with unencrypted numeric value

### Editing a Key

1. Click Edit button on any key row
2. Modal shows key metadata (read-only)
3. Modify name or value
4. Toggle show/hide value
5. Change encryption (warning displayed)
6. Click "Save Changes"
7. ✅ Key updated

## Known Limitations

1. **Format Field Client-Side Only:**
   - The "format" field is not stored in the backend database
   - Format is used for client-side validation only
   - All values are stored as text in the database
   - Future enhancement: Add `format` column to `key` table in backend

2. **Search Pagination:**
   - Search is client-side, so only searches current page
   - Consider adding server-side search parameter in future

3. **No Bulk Operations:**
   - Delete/update one key at a time
   - Could add multi-select for batch operations

4. **Value Masking:**
   - CSS-based masking may not work in all browsers
   - Consider more robust masking solution

## Security Considerations

1. **Encryption Enforcement:**
   - Only Text, JSON, YAML can be encrypted (per requirements)
   - Number, Integer, Boolean cannot be encrypted
   - UI enforces this with disabled checkbox

2. **Value Exposure:**
   - List view: Values are redacted (API behavior)
   - Detail view: Values are decrypted (requires explicit fetch)
   - Edit modal: Values are masked by default with toggle

3. **Access Control:**
   - Keys are scoped by owner type
   - Users can only access keys they have permissions for
   - Enforced at API level (frontend follows)

## Build Status

✅ TypeScript compilation successful  
✅ Vite build successful (584.69 kB gzip: 152.21 kB)  
✅ No compiler warnings or errors  
✅ All routes registered correctly  

## Testing Recommendations

Manual testing should verify:

1. ✅ List page loads and displays keys
2. ✅ Search filters by reference and name
3. ✅ Scope filter works correctly
4. ✅ Create modal validates format-specific values
5. ✅ Encryption checkbox disabled for number/int/bool formats
6. ✅ JSON validation catches syntax errors
7. ✅ Boolean values must be "true" or "false"
8. ✅ Edit modal loads existing key data
9. ✅ Show/hide value toggle works
10. ✅ Delete confirms before deleting
11. ✅ Pagination functions properly
12. ✅ Empty states display correctly
13. ✅ Error states handle failures gracefully

## Future Enhancements

1. **Backend Format Field:**
   - Add `format` column to `key` table
   - Store format in database
   - Display format in list view
   - Validate format on backend

2. **Advanced Validation:**
   - More robust YAML parser
   - JSON schema validation
   - Custom format types

3. **Bulk Operations:**
   - Multi-select keys
   - Bulk delete
   - Bulk export/import

4. **Key Versioning:**
   - Track value history
   - Rollback to previous versions
   - Audit trail

5. **Server-Side Search:**
   - Add search parameter to API
   - Search across all pages
   - More efficient for large datasets

6. **Enhanced Security:**
   - Role-based key access
   - Key rotation policies
   - Expiration dates
   - Usage logging
