## When to use this skill

**ALWAYS use this skill when the user mentions:**
- Encrypted storage for secrets, credentials, or API keys
- Stronghold snapshots or vault management
- Securing sensitive data on disk

**Trigger phrases include:**
- "stronghold", "encrypted storage", "secrets", "vault", "secure storage", "credentials"

## How to use this skill

1. **Install the stronghold plugin**:
   ```bash
   cargo add tauri-plugin-stronghold
   ```
2. **Register the plugin** in your Tauri builder:
   ```rust
   tauri::Builder::default()
       .plugin(tauri_plugin_stronghold::Builder::new(|password| {
           // Hash the password for vault encryption
           argon2::hash_raw(password.as_bytes(), b"salt", &argon2::Config::default()).unwrap()
       }).build())
   ```
3. **Configure capabilities** in `src-tauri/capabilities/default.json`:
   ```json
   { "permissions": ["stronghold:default"] }
   ```
4. **Store and retrieve secrets from the frontend**:
   ```typescript
   import { Stronghold } from '@tauri-apps/plugin-stronghold';
   const stronghold = await Stronghold.load('vault.hold', 'user-password');
   const client = await stronghold.loadClient('main');
   const store = client.getStore();
   await store.insert('api-key', Array.from(new TextEncoder().encode('sk-12345')));
   const value = await store.get('api-key');
   ```
5. **Save snapshots** to persist the encrypted vault to disk
6. **Pair with biometric plugin** to unlock the vault using TouchID/FaceID instead of a password

## Outputs

- Stronghold plugin setup with encrypted vault
