💅 crypto_free_shash(9) 💅

okay so this is a page from the Kernel API Manual — yes, the actual kernel man pages, we're in the big leagues now bestie 🎀

---

✨ NAME ✨

crypto_free_shash — zeroize and free the message digest handle 🧹💖

like, it wipes the thing clean AND frees it. two jobs, one function, main character energy fr.

---

🌸 SYNOPSIS 🌸

void crypto_free_shash (struct crypto_shash *tfm );

that's it. that's the whole call. no return value, no drama, just vibes 💅

---

🦋 ARGUMENTS 🦋

• tfm — the cipher handle that's getting freed 🫶 this is the one you're letting go of, bestie.

---

⭐ DESCRIPTION ⭐

So here's the thing, and it's genuinely the nicest little safety net ever: if tfm is a NULL pointer or an error pointer, this function just... does nothing. 🧚 zero. zilch. It does not freak out, it does not crash, it does not make you look bad in front of the whole group chat. It simply vibes. no cap.

lowkey iconic behaviour tbh — guard clauses are the moment 💜
