Win32_Hash

win32hash Password hashing and verification for Windows, written in Ada/SPARK. It derives a hash with PBKDF2-HMAC-SHA256 through the Windows CNG API bcrypt, generates a random salt, stores it as Base64, and wipes every secret it touches. Almost all of the code is proved with GNATprove; the few...

The Prover Is the Judge: Verified Security Software from AI Coding Agents in Ada/SPARK

AI coding agents produce code faster than humans can review it. In our approach, the prover is the judge of whether the code is correct. Under a verifier-driven loop, AI agents wrote and verified bare-metal security software in Ada/SPARK spanning classical and post-quantum cryptography, TLS 1.3,...
