关于SharedPreference与SQLite的认知确认及正误修正请求

Hey Kai, great job grasping the core ideas! Let's refine a few details in your understanding to make it fully accurate:

SharedPreferences #

• ✅ Correct points: Stores private primitive data in key-value pairs, is ideal for small datasets, and saves data in an XML file.
• ❌ Key corrections on security:
  • By default, SharedPreferences are private to your app — other apps can't access them unless you explicitly set an insecure access mode (not recommended) or the device is rooted.
  • They aren't encrypted out of the box, but you can manually encrypt values before storing them if you need enhanced security. The XML file is plaintext, but it's not readily accessible to non-rooted third-party apps.

SQLite #

• ✅ Correct points: A serverless local database that works well for both small and large structured datasets.
• ❌ Key corrections on security:
  • SQLite databases are not encrypted by default — they exist as plaintext files on the device. You’ll need to use third-party tools like SQLCipher to encrypt the entire database if security is a concern.
  • Like SharedPreferences, the default database file is private to your app. However, rooted devices or apps with special system permissions can still access it. It’s more suitable for structured data than SharedPreferences, but it’s not inherently encrypted or completely inaccessible externally.

If you have follow-up questions about secure storage implementation or choosing between these two options, feel free to ask!
