aes_decrypt(9)

💖 aes_decrypt(9) — Kernel API Manual but make it cute 💖

okay so bestie, this is the aes_decrypt(9) page from the Kernel API Manual, and it's literally about decrypting one AES block. tiny job, main character energy. 💅

---

✨ NAME ✨

• aes_decrypt — Decrypt a single AES block. that's the whole assignment, no cap. 🎀

---

🦋 SYNOPSIS 🦋

here's the exact signature, copied with love and zero edits:

void aes_decrypt (const struct aes_key *key , u8 out[static
       AES_BLOCK_SIZE] , const u8 in[static AES_BLOCK_SIZE] );

---

🌸 ARGUMENTS 🌸

• key — the AES key, previously initialized by aes_preparekey. so it's gotta be the prepared one, bestie. 🔑
• out — buffer to store the plaintext block. this is where the decrypted tea lands. 🍓
• in — buffer containing the ciphertext block. the scrambled icon you're feeding in. 💜

---

✨ CONTEXT ✨

Any context. literally any. no context restrictions mentioned here, so go off. 🌈
