STRUCT HMAC_SHA384_CTX(9)

✨ struct hmac_sha384_ctx(9) ✨

okay bestie, welcome to the Kernel API Manual 💖 this is the page for struct hmac_sha384_ctx, and it's literally the context for computing HMAC-SHA384 of a message. no cap.

---

🌸 NAME 🌸

struct hmac_sha384_ctx — context for computing HMAC-SHA384 of a message. That's the whole assignment, bestie. 💅

---

🎀 SYNOPSIS 🎀

here's the struct, copied exactly so nothing gets lost:

struct hmac_sha384_ctx {
    struct __hmac_sha512_ctx ctx;
 };

it's giving "small struct, big responsibilities" energy 🔥

---

🧩 Members 🧩

• ctx — private 🙈 that's it, that's the member. don't go poking at it, it's private.
