STORAGE questions

Secure storage in React Native can be managed using libraries such as `react-native-keychain` or `react-native-sensitive-info`. These libraries provide a secure way to store sensitive information like tokens or passwords using platform-specific secure storage mechanisms (e.g., Keychain on iOS and Keystore on Android). They encrypt the data and ensure it is stored securely.

Handling JWT token storage on the client side requires careful consideration to ensure security. Common methods include storing tokens in HTTP-only cookies to prevent JavaScript access, which helps mitigate XSS (Cross-Site Scripting) attacks. Alternatively, tokens can be stored in secure storage mechanisms such as localStorage or sessionStorage, but this approach may expose tokens to XSS risks. Always ensure that tokens are transmitted over HTTPS to prevent interception and that they are managed with appropriate expiration and renewal policies.

Best practices for implementing JWT in a web application include: 1) Use strong, well-established algorithms for signing the tokens (e.g., RS256). 2) Securely store JWTs on the client side using HTTP-only cookies to protect against XSS attacks. 3) Implement token expiration and renewal policies to limit token lifespan and reduce risk. 4) Validate tokens properly on the server side, including checking claims and verifying signatures. 5) Use HTTPS to secure token transmission and prevent interception. 6) Avoid storing sensitive data directly in JWTs, as they can be decoded by anyone with the token.

MyISAM is a non-transactional storage engine, ideal for read-heavy applications, while InnoDB supports transactions, foreign keys, and row-level locking, making it suitable for high-concurrency environments. For instance, InnoDB is preferable for e-commerce sites where data integrity is critical.
