LIBKECCAK(7)

💅 libkeccak — okay bestie, let me tell you about this one

So the page header says LIBKECCAK(7) and it lives in the Miscellaneous Information Manual, which is basically the group chat of man pages. Welcome, it's cozy here. 🎀

---

✨ NAME ✨

libkeccak — the Keccak-family hashing library, and yes she is that girl 💖

---

🌸 DESCRIPTION 🌸

Okay so libkeccak is a bit-oriented, lanewise implementation of the Keccak family. Read that again. Lanewise. She's doing lane math. Ngl, it's giving main character energy. 👑

And she does not just do the one thing, bestie. The feature list is stacked:

• support for extend output size (yes I said what I said, she can keep going) 🌈
• state marshalling — so you can pack the state up and send it on its way 📦
• algorithm tuning with implicit parameters — she just knows, iykyk 🦋
• secure erasure of sensitive data — memory hygiene is self care, fr fr 🧼
• HMAC support, because authentication matters 💅

Like, the whole package. Obsessed. 😭

---

🔥 FUTURE DIRECTION 🔥

Keccak-3200 may be implemented in the future.

Manifesting it. Not yet, though — do not go looking for it. Future us gets to have that. ⭐
