The library abstracts platform-specific encryption implementations (Android KeyStore, iOS Keychain) and allows developers to store key-value pairs securely using Compose state or Kotlin flows. It supports serializable data classes, automatic persistence on value changes, and optional biometric authentication, eliminating the need to write platform-specific encryption code for each target platform. ## Full article daily.dev links to this article rather than hosting it.
