🔐 Key Enhancements in CryptoKit

1. Support for PEM and DER Formats

CryptoKit now directly supports PEM and DER formats, allowing developers to initialize public and private keys without relying on external libraries for format conversion.

2. Introduction of HKDF APIs

The framework has introduced APIs for HMAC-based Extract-and-Expand Key Derivation Functions (HKDF), enabling the derivation of multiple keys from a single master secret. This is particularly useful for secure communication protocols and authentication mechanisms.

3. Enhanced Portability with Swift Crypto

Through the Swift Crypto open-source project, CryptoKit's functionalities are now accessible across all platforms supported by Swift, including Linux. This cross-platform compatibility facilitates the development of secure applications beyond the Apple ecosystem.
