#AppleCryptoUpdate Apple's CryptoKit has seen notable updates in 2025, enhancing its capabilities for developers focused on security and cryptography.

🔐 Key Updates in CryptoKit (2025)

PEM-Based RSA Key Support: As of February 2025, CryptoKit now supports importing PEM-based RSA private keys and their certificates. This addition simplifies the process of integrating existing RSA keys into your applications.

Enhanced Key Format Support: CryptoKit has expanded its support to include PEM and DER formats for elliptic curve keys. Developers can now directly initialize CryptoKit public and private keys using these formats, eliminating the need for external conversion tools.

HKDF API Enhancements: The framework introduces new APIs for HMAC-based Extract-and-Expand Key Derivation Functions (HKDF). These APIs offer both one-shot and two-step extract-and-expand variants, providing flexibility for various key derivation needs
