Apple's formal verification of corecrypto is deep technical content for security-minded engineers.
Summary
Apple open-sourced formal verification proofs for its post-quantum ML-KEM and ML-DSA implementations in corecrypto, the foundational cryptographic library running on 2.5 billion devices. The proofs mathematically verify correctness against FIPS 203/204 standards, covering iMessage, VPN, and TLS, and Apple released the verification tools to advance high-assurance cryptography.
