ovpn_aead_crypto_tmp_iv(9)

💅 NAME 💅

ovpn_aead_crypto_tmp_iv — okay so bestie, this one grabs you the pointer to the IV inside a temporary buffer that you already allocated with ovpn_aead_crypto_tmp_size. That's the whole vibe ✨

---

🎀 SYNOPSIS 🎀

u8 * ovpn_aead_crypto_tmp_iv (struct crypto_aead *aead , void *tmp );

---

🌸 ARGUMENTS 🌸

• aead — the AEAD cipher handle, your main character 🔥
• tmp — a pointer to the very beginning of the temporary buffer, like the front door of the whole thing 🚪

---

🦋 DESCRIPTION 🦋

So what this function does is retrieve a pointer to the initialization vector (IV) sitting inside that temporary buffer. Easy.

But here's the lil plot twist 🫶 — if the AEAD cipher specifies an IV size, the pointer gets adjusted using the AEAD's alignment mask, so everything lands properly aligned. Alignment is not optional, it's a lifestyle 💅

---

⭐ RETURN ⭐

A pointer to the IV within the temporary buffer. That's it, that's the gift 🎁
