- **Tauri APIs**: Access native functionalities seamlessly through Tauri APIs, providing your app with the potential to interact with the user's system.

## How It Works

Passwords are stored locally in an **encrypted file** on the user's device using **CryptoJS (AES encryption)**, ensuring that sensitive information remains confidential and secure.

> **Important:** There is **no "forgot password" option**. If you lose your email/password credentials, you will **not** be able to decrypt your password file, and your stored data will be inaccessible. Please ensure you store your credentials safely.

### Storage Mechanism

- Each user's passwords are saved in a unique file named after a **SHA256 hash of their email and password combination**.

- Files are saved in the system’s **AppData directory** (via Tauri’s `BaseDirectory.AppData`), which varies based on the operating system.

### Encryption Flow

1. **Authentication**:

- When a user logs in, their email and password are used to generate a hash-based file name.

- If the file exists, it's read and **decrypted using AES** with the same email+password as the key.

- If not, a new encrypted file is created with an empty password array.

2. **Saving Passwords**:

- When passwords are added, edited, or deleted, the updated array is **encrypted using AES** and written back to the same file.

- AES keys are never stored—encryption is dynamically tied to the email/password pair used during authentication.

3. **Encryption Details**:

- **AES-256** symmetric encryption via CryptoJS.

- Keys are derived directly from the concatenation of email and password (e.g., `email + password`).

- Password data is never sent or stored remotely.
