STRUCT HMAC_SHA224_CTX(9)

💖 struct hmac_sha224_ctx(9) 💖

okay so real talk bestie, this page lives in the Kernel API Manual and it's literally just about one lil struct: struct hmac_sha224_ctx. That's it. That's the whole vibe. It's the context you carry around while you're computing an HMAC-SHA224 of a message ✨

🌸 NAME 🌸

struct hmac_sha224_ctx — the context for computing HMAC-SHA224 of a message 🫶

🎀 SYNOPSIS 🎀

struct hmac_sha224_ctx {
    struct __hmac_sha256_ctx ctx;
 };

not me noticing the closing brace is indented one space off from the opening one 😭 that's literally how it's written in the source, keep it exactly like that, no touchy 💅

🦋 Members 🦋

• ctx — private 🙈 that's the whole description. it's a struct __hmac_sha256_ctx and it's private, so like... don't poke it, bestie. it's giving internal business.
