## Introduction

`safe-encrypted-storage` simplifies the process of storing encrypted data in either `localStorage` or `sessionStorage`. It uses IndexedDB to securely store encryption keys and ensures that all data stored is both encrypted and decrypted seamlessly in the background. This package is perfect for applications requiring sensitive data storage, adding an extra layer of security without the need for complex encryption management.

## Installation

You can install the package via npm:

```bash
npm install safe-encrypted-storage
```

## Usage

Here's an example of how to use `safe-encrypted-storage`:

```javascript
import { SafeStorage } from 'safe-encrypted-storage';

(async () => {
const mechanism = 'localStorage'; // Or 'sessionStorage'
const safeStorage = SafeStorage.init(mechanism);

// Storing encrypted data
await safeStorage.setItem('username', 'john_doe');

// Retrieving decrypted data
const username = await safeStorage.getItem('username');
console.log(username); // Outputs: john_doe

// Removing data
await safeStorage.removeItem('username');

// Clearing all storage
safeStorage.clear();
})();
```

## API

### `getItem(key: string): Promise`

Retrieves and decrypts the value associated with the specified key.

### `removeItem(key: string): Promise`

Removes the value associated with the specified key from storage.

### `clear()`

Clears all data from the selected storage mechanism.
