How do you store sensitive information in your app in iOS?
Best practices for storing user data
- Apple’s App Sandbox. All apps running on iOS run in a sandbox to make sure the app can only access data which is stored in the app’s unique home directory.
- Data Protection API.
- Keychain.
- HTTPs.
- SSL Pinning.
- Push Notifications.
- End-to-end encryption.
- Hashing data.
What is the good way to protect user password in app backend?
You can think about the following steps to protect the password:
- Use HTTPS preferably with HSTS to protect the passwords during transport;
- Use a password hash such as bcrypt instead of MD5 to protect the password on the server. HASH passwords with salt; use a high work factor for bcrypt.
Is it OK to use hash salt in iOS 7?
Developing an enterprise iOS 7 mobile application, currently the user gets authenticated using his credentials (username and password) to dedicated Server. But we need to provide offline authentication as well, as network connectivity is a major issue. The user gets authenticated. If offline mode verify with the hash. Is this approach fine? OR
What do you need to know about cryptographic hashing?
You’ll work with some basic cryptographic hashing methods to securely store user input in the iOS keychain – keeping your users’ data private and protected. Apple has several APIs that will help keep your applications secure, and you’ll explore these while working with the keychain.
Why is it important to use a keychain in iOS?
One of the most important security elements for Apple developers is the iOS Keychain, which is a specialized database for storing metadata and sensitive information. Using Keychain is the best practice for storing small pieces of data that are critical to your app such as secrets and passwords.
