sha384_final(9)

💅 sha384_final(9) — like, the grand finale of your SHA-384 hash 🎀

okay so real talk, bestie: this is a page from the Kernel API Manual, section 9, and it's all about sha384_final — the little function that wraps up your SHA-384 digest and then minds its own business by wiping the evidence. iconic behavior honestly ✨

---

🌸 NAME 🌸

sha384_final — finish computing a SHA-384 message digest 🦋

---

✨ SYNOPSIS ✨

void sha384_final (struct sha384_ctx *ctx , u8 out[static
SHA384_DIGEST_SIZE] );

no like, that's literally it. two args, one void, zero drama 💅

---

🎀 ARGUMENTS 🎀

• ctx — the context you're finalizing, and heads up: it must have been initialized already. don't come at it raw, bestie 🙈
• out — the output 💖 this is where the resulting SHA-384 message digest lands, so it's giving "main character" energy for sure.

---

🔥 DESCRIPTION 🔥

so after it finishes doing its thing, this bad boy zeroizes ctx. yep, wipes it. so the caller does not need to do it themselves — no cap, that's one less chore for you 🫶

like it's giving "I'll clean up after myself, you're welcome" and honestly? obsessed 💜

---

🧚 CONTEXT 🧚

Any context. literally any. no constraints, we love a low-maintenance icon ⭐

💖 tiny reminder bestie: ctx must be initialized before you call this. that's not a suggestion, that's the vibe check. 💅

🌸 okay that's the whole page, and it comes to you straight from ./include/crypto, dated October 2026 — mwah, go forth and finalize those digests, iykyk 🍓🫶
