Hawk
Hawk is a secure local storage library and persistence API for Android. It provides a framework for saving and retrieving primitives, objects, and collections using a key-value storage system.
The library features an encrypted storage wrapper that secures data through a pluggable crypto provider, including a fallback mechanism to non-encrypted mode. Its architecture allows for custom storage backend implementations and interface-based component injection to replace default serialization, parsing, and conversion processes.
The system supports type-preserving serialization and includes utilities for managing the data lifecycle, such as targeted entry removal and bulk state resets. It also incorporates a system log interception capability to capture and process internal messages.
Features
- Key-Value Storage Wrappers - Offers a simplified, secure API wrapper for saving and retrieving key-value data on Android devices.
- Local Persistence Implementations - Provides a concrete implementation of local persistence for Android with support for custom backends.
- Key-Value Pair Managers - Provides a structured key-value mapping system for organizing and managing local device data.
- Local State Management - Manages app settings and user preferences on Android through a persistent local cache.
- Android App Data Management - Handles the lifecycle of internal Android app data, including key verification and state wiping.
- Secure Storage - Secures sensitive key-value pairs on Android using encrypted local storage to ensure data privacy.
- Data Reset Utilities - Includes utilities to remove specific entries by key or wipe all local data to reset application state.
- Backend Implementation Extensions - Provides an extensibility mechanism to implement custom storage or encryption layers for data persistence.
- Data Serialization Frameworks - Provides a customizable framework for converting and serializing data types before committing them to storage.
- Type Fidelity Preservation - Ensures that original data types of primitives and collections are fully recoverable after serialization.
- Pluggable Storage Backends - Decouples business logic from storage by allowing the swap of diverse storage backend implementations.
- Encrypted Storage Layers - Implements a persistence layer that secures mobile storage through pluggable encryption components.
- Data Encryption - Implements custom encryption layers and crypto providers to secure application data at rest on mobile devices.
- Pluggable Crypto Providers - Implements a pluggable crypto provider system to secure key-value pairs with a fallback to non-encrypted mode.
- Component Implementation Injection - Allows replacing default serialization, parsing, and conversion components with custom implementations via interfaces.
