set_key_size_des(9)

💅 set_key_size_des(9)

okay so welcome to the set_key_size_des(9) page, bestie — this is a Kernel API Manual situation and it's honestly tiny but iconic 🎀

---

✨ NAME ✨

set_key_size_des — literally just sets the DES key size. that's the whole vibe, no cap 💖

---

🌸 SYNOPSIS 🌸

void set_key_size_des (struct cc_hw_desc *pdesc , u32 size );

it returns void, so like… it gives nothing back, it just does the thing 🦋

---

💅 ARGUMENTS 💅

• pdesc — a pointer to the HW descriptor struct. yes queen, hand over the descriptor 📨
• size — the key size in bytes. and hear me out: this is the size in bytes, NOT the size code 😭 do not come in here with a size code, that's a different thing entirely, iykyk

💀 reminder that size means bytes, not a size code. i'm not being dramatic, i'm being accurate. periodt.

and that's the page, bestie!! 🫶 this cutie came out of the ./drivers/crypto/ccree corner of the kernel and it's dated October 2026 ⭐ go forth and set those DES key sizes responsibly 👑💜
