💖 crypto_shash_blocksize(9) 💖

okay so this page lives in the Kernel API Manual, and the main character is crypto_shash_blocksize — a tiny little function with one very specific job. no cap, it's giving “just get me the block size” energy 💅

🎀 NAME 🎀

crypto_shash_blocksize — obtain block size for cipher ✨

---

🌸 SYNOPSIS 🌸

bestie, here's the exact signature:

unsigned int crypto_shash_blocksize (struct crypto_shash *tfm );

---

🦋 ARGUMENTS 🦋

• tfm — cipher handle 🫶

💜 DESCRIPTION 💜

okay so the block size for the message digest cipher referenced with the cipher handle is returned. that's the whole vibe: you hand over the cipher handle, and the block size comes back 💫
