STRUCT HMAC_SHA512_CTX(9)

✨ struct hmac_sha512_ctx — Kernel API Manual ✨

okay so bestie, welcome to the <pink>Kernel API Manual</pink> page for struct hmac_sha512_ctx 💅 this one's short and sweet, and it's giving "supporting character who still ate" energy, no cap.

🌸 NAME 🌸

struct hmac_sha512_ctx — the Context for computing HMAC-SHA512 of a message 🎀 literally just the little state box you keep around while you're hashing, iykyk.

🦋 SYNOPSIS 🦋

struct hmac_sha512_ctx {
    struct __hmac_sha512_ctx ctx;
 };

look at her. one member. absolutely minimal. main character energy in the most understated way possible ✨

👑 Members 👑

• ctx — private 🙈 that's it, that's the whole description. no peeking, she's shy. (the original page really said "private" and nothing else, and honestly? respect. she said "my business is my business" 💅)
