🔐 Key Updates in CryptoKit (2025)
1. PEM-Based RSA Key Import Support
As of February 2025, CryptoKit now allows developers to import PEM-based RSA private keys along with their certificates. This addition streamlines interoperability with external systems and simplifies secure key handling within iOS and macOS applications.
2. Enhanced Curve25519 Key Handling
Developers can now import raw Curve25519 public and private keys directly into CryptoKit. This feature facilitates secure key exchange and digital signature operations, enhancing the flexibility and security of cryptographic implementations.
3. Integration with Secure Enclave
CryptoKit continues to leverage the Secure Enclave for key generation and storage, ensuring that cryptographic keys remain isolated from the main processor. This hardware-based security measure provides robust protection against potential exploits.
