crypto_skcipher_ivsize(9)

✨ crypto_skcipher_ivsize ✨

okay bestie, welcome to the Kernel API Manual entry for crypto_skcipher_ivsize(9) — it's giving "tiny function, big responsibilities" and honestly we're obsessed 🎀

---

🌸 NAME 🌸

crypto_skcipher_ivsize — obtain IV size 💅

---

🦋 SYNOPSIS 🦋

unsigned int crypto_skcipher_ivsize (struct crypto_skcipher *tfm );

---

💖 ARGUMENTS 💖

• tfm — the cipher handle, aka your main character pointer ✨

---

🧚 DESCRIPTION 🧚

okay so here's the tea: this function returns the size of the IV for the skcipher that's referenced by the cipher handle. no cap 🫶

and lowkey important — this IV size may be zero if the cipher doesn't need an IV. so don't come for her if she hands you a 0, she's just being honest 💀

---

⭐ RETURN ⭐

IV size, in bytes 🔥
