Overview
EncryptedSharedPreferences is a Flutter plugin that securely stores key-value pairs by encrypting data before saving it to device storage. It extends the functionality of SharedPreferences with end-to-end encryption, ensuring sensitive information like tokens, passwords, or user preferences remain protected from unauthorized access. The plugin uses strong encryption algorithms and integrates seamlessly with Android, iOS, Web, macOS, Windows, and Linux platforms. Ideal for apps requiring secure local data persistence without exposing credentials.
