crypto_shash_digestsize(9)

💅 crypto_shash_digestsize(9) — like, the Kernel API Manual, bestie ✨

Okay so welcome to the crypto_shash_digestsize page, part of the Kernel API Manual (yes that one 🎀). It's a little one but she's iconic, let's get into it.

---

🌸 NAME 🌸

crypto_shash_digestsize — obtain message digest size 💖

---

✨ SYNOPSIS ✨

unsigned int crypto_shash_digestsize (struct crypto_shash *tfm );

That's it. That's the whole vibe. 🦋

---

🎀 ARGUMENTS 🎀

• tfm — the cipher handle, bestie 💅 that's your little key to the whole thing

---

👑 DESCRIPTION 👑

So basically: you hand over that cipher handle (tfm), it points at some message digest cipher, and this function returns the size of the message digest that cipher creates. That's it, that's the whole function, no cap. ✨

---

⭐ RETURN ⭐

The digest size of the cipher, bestie 🫶 — literally just the number, go off.
