💜 asymmetric_key_subtype(9) — a Kernel API Manual moment

okay so bestie, welcome to the asymmetric_key_subtype(9) page 💅 this is a little kernel API helper, and honestly? she's short, she's sweet, she does exactly one thing. lowkey iconic.

---

✨ NAME ✨

asymmetric_key_subtype — bestie, this is literally the function that gets the subtype from an asymmetric key 🦋

---

✨ SYNOPSIS ✨

struct asymmetric_key_subtype * asymmetric_key_subtype (const struct key
*key );

like, that's the whole vibe. she returns a pointer to a struct asymmetric_key_subtype and takes one arg. no cap.

---

✨ ARGUMENTS ✨

• key — the key of interest 🎀 (yes, that's the actual wording, and honestly it's giving main character energy — the key in question, the one you're curious about, the one we're looking at)

---

✨ DESCRIPTION ✨

so here's the tea ☕ this function retrieves the subtype pointer of the asymmetric key — and she gets it from the type-specific data that's attached to the key 🔥

that's it. that's the whole thing. she reaches into the key's type-specific data, pulls out the subtype pointer, and hands it right back to you. efficient queen 👑

---

✨ SEE ALSO ✨

• Kernel file ./include/keys/asymmetric-subtype.h — go read it, iykyk 📖✨

ngl this one is a short read, but every detail counts, so don't skip the header file bestie 🫶

🌸 okay that's the page!! this lil gem lives in ./include/keys and the date on it is October 2026 — so like, mark your calendar or whatever 😭💖 🎀
