Security framework

Objective C applications can handle data storage and encryption through various techniques and frameworks. The most common approach is to use the Core Data framework for data storage, which allows developers to manage object graphs and store data in a persistent store. For encryption, Objective C provides the Security framework, which offers a range of cryptographic services and algorithms. Developers can use these services to encrypt and decrypt data, generate secure keys, and authenticate users. By combining Core Data and the Security framework, Objective C applications can securely store and retrieve sensitive data.
