crypto_ahash_blocksize(9)

💅 crypto_ahash_blocksize — like, the blocksize one, bestie ✨

okay so real talk, this is a page from the Kernel API Manual (section 9, crypto_ahash_blocksize(9)), and it's honestly so short and so cute — it does exactly one thing and it does it flawlessly. main character energy fr fr 🎀

🌸 NAME 🌸

crypto_ahash_blocksize — obtain block size for cipher

like... that's it. that's the whole job. she gets the block size. iconic. 👑

---

✨ SYNOPSIS ✨

unsigned int crypto_ahash_blocksize (struct crypto_ahash *tfm );

note the unsigned int out front — she's giving you a number back, no cap 💜

---

🦋 ARGUMENTS 🦋

• tfm — cipher handle. that's your lil' reference to the message digest cipher you're obsessed with rn. you hand it over, she looks at it. simple as that 🫶

---

💖 DESCRIPTION 💖

okay so picture this: you've got a cipher handle, right? and it's pointing at some message digest cipher. this function literally just goes "yeah, and what's her block size?" and returns it to you.

the block size for the message digest cipher referenced with the cipher handle is returned. that's the whole vibe check. nothing else happens. no side quests. 💅

---

🌈 RETURN 🌈

block size of cipher. a whole unsigned int of it. slay. ⭐
