ECDH HELPER FUNCTIONS(9)

💅 ECDH Helper Functions 💅

okay bestie, this one's from the Kernel API Manual and it's basically the little cheat sheet for making ECDH behave with the KPP cipher API — here's the whole vibe ✨

🦋 the actual deal

So, to use ECDH with the KPP cipher API, you're gonna want this data structure and these functions. That's the whole assignment, fr fr 🫶

The ECC curves that the ECDH implementation actually knows about? Those are specified in this header file. iykyk 🌸

🔑 using ECDH with KPP

To use ECDH with KPP, these are the functions you reach for when you're operating on an ECDH private key 👑

The packet private key — the one you can set with the KPP API function call of crypto_kpp_set_secret — that's the one in question, no cap. 💅

ngl this section is short but it's lowkey the main character energy of the whole page 😭
