Question 1

How do I use CocoaSecurity in a Swift project?

Accepted Answer

You need to add a bridging header to import CocoaSecurity into Swift. Create a header file in your Xcode project, import the CocoaSecurity classes, and then you can use them in Swift code with Objective-C interoperability, though it may feel clunky compared to native Swift libraries.

Question 2

Is MD5 still safe to use with CocoaSecurity?

Accepted Answer

No, MD5 is considered cryptographically broken and should be avoided for security-sensitive tasks like password hashing. CocoaSecurity includes it for legacy compatibility, but developers should opt for stronger hashes like SHA256 or SHA512 for modern applications.

Question 3

CocoaSecurity vs CommonCrypto: which is better for iOS?

Accepted Answer

CocoaSecurity is higher-level and easier for common tasks like AES encryption and hashing, while CommonCrypto is Apple's lower-level framework offering more control and performance. Choose CocoaSecurity for simplicity and quick integration, but CommonCrypto for advanced or optimized cryptographic operations.

Question 4

How to securely generate AES keys with CocoaSecurity?

Accepted Answer

Avoid the default key derivation method for critical security; instead, generate cryptographically random keys and IVs using SecureRandom or similar APIs, then pass them as hex strings to the AES encrypt/decrypt methods as shown in the README's custom key example.

Question 5

Does CocoaSecurity support encryption for large files?

Accepted Answer

No, the library is designed for in-memory data operations, so for large files, you'll need to manually chunk the data or implement streaming, which isn't built-in and adds development overhead.
