💅 crypto_alloc_kpp(9) — Kernel API Manual 💅

okay so bestie, welcome to the crypto_alloc_kpp(9) page from the Kernel API Manual. this one is short and sweet, but it's giving “important little helper” energy, so let's get into it. 🫶✨

---

🌸 NAME 🌸

crypto_alloc_kpp — allocate KPP tfm handle 💖

---

🎀 SYNOPSIS 🎀

struct crypto_kpp * crypto_alloc_kpp (const char *alg_name , u32 type ,
u32 mask );

---

✨ ARGUMENTS ✨

• alg_name — is the name of the kpp algorithm (e.g. "dh", "ecdh"). that's the “which one are we allocating?” name, fr fr.
• type — specifies the type of the algorithm. 🦋
• mask — specifies the mask for the algorithm. 💅

---

💜 DESCRIPTION 💜

Allocate a handle for kpp algorithm. the returned struct crypto_kpp is required for any following API invocation — no cap, it's literally the handle you need for the next calls. 👑

---

🔥 RETURN 🔥

allocated handle in case of success; IS_ERR is true in case of an error, and PTR_ERR returns the error code. so like, check the vibe before you keep going. 💀✨
