SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill provides production-grade client-side encryption for Expo/React Native apps, ensuring sensitive data (journal entries, health data, PII) is encrypted with secure key storage and integrity checks.

Core Features & Use Cases

  • AES-256-CBC encryption with keys stored securely in expo-secure-store.
  • Encrypt-then-MAC to verify data integrity before decryption.
  • Platform-agnostic crypto flows for native and web environments, with encrypted storage in SQLite.

Quick Start

Set up a sample project with expo-secure-store and crypto-js, then run a small snippet to initialize the key and encrypt a test string.

Frequently Asked Questions about expo-encryption-patterns

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I encrypt sensitive user data in an Expo React Native app?▼

Encrypt sensitive Expo app data using AES-256-CBC encryption with keys managed in expo-secure-store, ensuring PII and health data remain protected across native and web platforms.

What is the encrypt-then-MAC pattern for securing mobile app data?▼

The encrypt-then-MAC pattern verifies data integrity before decryption by generating a message authentication code after AES-256-CBC encryption, preventing tampering with stored sensitive data.

Can I use expo-secure-store for AES-256 key management on both native and web?▼

Yes, expo-secure-store supports AES-256 key management across native and web platforms, enabling platform-agnostic crypto operations for secure key storage and retrieval.

How do I integrate SQLite encrypted storage with React Native?▼

Integrate SQLite encrypted storage by applying AES-256-CBC encryption to sensitive data before writing it to the database, enabling secure local storage of journal entries and PII.

Does this client-side encryption approach work for securing PII in mobile apps?▼

Yes, this approach secures PII in mobile apps by applying production-grade AES-256-CBC encryption with secure key management in expo-secure-store, protecting sensitive user information locally.
