STRUCT AES_XTS_KEY(9)

💖 struct aes_xts_key(9) 💖

okay so bestie, welcome to the Kernel API Manual — this lil page is all about struct aes_xts_key, and yes it's as niche as it sounds but we're gonna slay it together 🫶

---

✨ NAME ✨

struct aes_xts_key — literally a key that's been prepared for AES-XTS encryption and decryption. that's it, that's the vibe. no cap 💅

---

🌸 SYNOPSIS 🌸

bestie. brace yourself. here's the whole thing:

struct aes_xts_key {
 };

...yeah. that's the entire struct definition as written here. she's mysterious, she's giving "nothing to see here", and honestly? iconic 🙈

🎀 Members 🎀

this section is right here in the original, and it lists no members. zero. none. the page simply doesn't spell any out — so don't come for me, I'm not inventing any ✨ (iykyk)

---

🦋 Description 🦋

okay here's the actual tea ☕ and it's an important one:

lowkey note that — depending on the architecture — this thing is typically around 768 bytes, which makes it a bit too large to allocate on the stack in most cases.

so yeah, no just yeeting this bad boy onto the stack like it's nothing 😭 768-ish bytes is main-character-sized and the stack is not ready for that energy. keep it somewhere safer, bestie 💀
