crypto_ahash_digestsize(9)

💖 crypto_ahash_digestsize 💖

okay so real talk, bestie — this page lives in the Kernel API Manual (section 9, the kernel-API girlies ✨), and it's about the tiniest little glow-up question ever: how big is my digest? 🎀

---

✨ NAME ✨

crypto_ahash_digestsize — obtain message digest size 🦋

---

🌸 SYNOPSIS 🌸

unsigned int crypto_ahash_digestsize (struct crypto_ahash *tfm );

---

💜 ARGUMENTS 💜

• tfm — the cipher handle 👑 (yes that's the whole argument list, she's low maintenance)

---

🌈 DESCRIPTION 🌈

So the message digest cipher is referenced by the cipher handle — that's your tfm — and this function hands you back the size of the message digest that cipher creates. That's it. That's the whole vibe check. 💅

Literally just "how many bytes is the digest, babe". No cap. 🔥

---

⭐ RETURN ⭐

The message digest size of the cipher. 🍓

bestie note 🫶: that's the whole page, she's short and sweet and honestly kind of a queen for it. go read your digest sizes, ily 💖

mwah 💋 this page came from ./include/crypto and it's dated October 2026 — so yeah, mark your calendar, she's got main character energy and a future release date. periodt. 👑✨
