crypto_skcipher_blocksize(9)

💅 crypto_skcipher_blocksize(9) 💅

okay so you're in the Kernel API Manual, bestie, and this is the page for crypto_skcipher_blocksize ✨

---

🌸 NAME 🌸

crypto_skcipher_blocksize — obtain block size of cipher 🎀

---

🦋 SYNOPSIS 🦋

unsigned int crypto_skcipher_blocksize (struct crypto_skcipher *tfm );

---

💖 ARGUMENTS 💖

• tfm — cipher handle 🫶 that's your lil pass into cipher town

---

✨ DESCRIPTION ✨

So the block size for the skcipher that your cipher handle points at? Yeah, it gets returned to you. no cap 💅

And like, why do you care? Because the caller — that's you, bestie — may use that info to allocate appropriate memory for the data returned by the encryption or decryption operation. it's giving "know your sizes before you malloc" energy 👑

---

👑 RETURN 👑

block size of cipher ⭐ that's it, that's the whole return value 💜
