A Flutter plugin for securely storing sensitive key-value data using platform-specific encrypted storage such as iOS/macOS Keychain, Android Keystore with RSA OAEP + AES-GCM ciphers, and native secure mechanisms on Windows, Linux, and Web. It supports optional biometric authentication and cross-platform configuration options.
Use cases
- store auth tokens securely in a flutter app
- save sensitive user data with encryption on mobile
- add biometric-protected storage to an android flutter app
- persist secrets in the ios keychain from dart
- secure key-value storage across android ios and desktop
- store credentials encrypted on windows and linux flutter apps
When to choose
- you are building a Flutter app that needs encrypted storage of tokens, keys, or credentials
- you need cross-platform secure storage including mobile, desktop, and web
- you want optional biometric-gated access to stored secrets on Android or iOS
When to avoid
- you need a general-purpose database with queries rather than simple key-value secrets
- your web app is not served over HTTPS or localhost
- you are not using Flutter/Dart for your project
