High performance persistant memory key-value storage with AES256 encryption.

Features

• Persistant storage in document directory or directory provided.
• Supports encryption on rest.
• Can be used as Map alternative.

Planned Features

• Use IndexedDB instead of localStorage

Usage

void main() async {
  var localStorage = KVS<String, int>(
    name: 'storeName',
    cipher: AESGCM256(key: 'mySecretKey'),
  );

  await localStorage.init();

  localStorage['year'] = 2023;
  localStorage['year']; // 2023
  localStorage.length; // 1
  localStorage.addAll({
    'month': 1,
    'date': 1,
  });
  localStorage.length; // 3
}

Add encryption to existing storage

var localStorage = KVS<String, int>(
  name: 'storeName'
);

await localStorage.init();

localStorage.cipher = AESGCM256(key: 'mySecretKey');
localStorage.flush();

Remove encryption from existing storage

var localStorage = KVS<String, int>(
  name: 'storeName',
  cipher: AESGCM256(key: 'mySecretKey'),
);

await localStorage.init();

localStorage.cipher = null;
localStorage.flush();

Change encryption key of existing storage

var localStorage = KVS<String, int>(
  name: 'storeName',
  cipher: AESGCM256(key: 'oldSecretKey'),
);

await localStorage.init();

localStorage.cipher = AESGCM256(key: 'newSecretKey');
localStorage.flush();
