How do you properly implement encryption for a Hive box specifically to properly protect genuinely sensitive data stored directly on a user's own device from being easily read by another potentially malicious app?

Hive genuinely supports transparently encrypting an entire box's own stored data using AES encryption, and properly setting this up requires generating a genuinely secure encryption key, ideally storing that same specific key itself securely using something like flutter_secure_storage rather than simply hardcoding it directly, and then passing that specific key into the encryptionCipher parameter when actually opening a given particular box, ensuring any genuinely sensitive data, such as cached authentication tokens or personal user details, remains properly protected even if a malicious actor somehow gained direct access to the underlying raw stored Hive data file itself.

final encryptionKey = await secureStorage.read(key: 'hiveKey');
var box = await Hive.openBox('secureData', encryptionCipher: HiveAesCipher(base64Url.decode(encryptionKey!)));
