💅 NAME 💅

okay bestie, welcome to the Kernel API Manual ✨ this page is all about crypto_kpp_compute_shared_secret and its whole personality is Invoke kpp operation. That’s the vibe 🫶

✨ SYNOPSIS ✨

int crypto_kpp_compute_shared_secret (struct kpp_request *req );

🌸 RETURN 🌸

• zero — on success, slay ✅
• error code — in case of error, and yes that’s the whole mood 😭
