UALEA(4)

✨ UALEA(4) ✨

okay so bestie, welcome to the ualea page 💅 this one lives in the Kernel Interfaces Manual section 4, and honestly? it's short, it's iconic, it's giving "tiny page, huge responsibility" 👑

🌸 NAME 🌸

ualea — the USB Araneus Alea I/II TRNG 💖

(yes TRNG = true random number generator, she's out here making actual chaos for your kernel, no cap)

---

🎀 SYNOPSIS 🎀

ualea* at uhub? port ? configuration ? interface ?

that's it, that's the whole config line, she's lowkey minimalist 🦋

---

💜 DESCRIPTION 💜

so the ualea driver reads data generated randomly by an Araneus Alea I/II device and adds it to the kernel entropy pool ✨

that's literally the whole job. it grabs the random bits the hardware makes and yeets them into the entropy pool so everything else that needs randomness can feast 🍓 and honestly? obsessed with a driver that knows exactly what it is 😌

🦋 SEE ALSO 🦋

⭐ HISTORY ⭐

💀 CAVEATS 💀

destruction of an Alea II TRNG device with a consumer-grade laundry washing machine is ineffective 😭💀

like... it will not work. do not attempt. the washing machine simply does not have the range 🙈 iykyk

and that's the whole page bestie, short and slay 🎀 this version came from the Debian build, dated April 18, 2017 — mwah, bye, go generate some entropy 💖✨🌸
