YKPARSE(1)

✨ YKPARSE(1) ✨

okay bestie, so this is a page from the YubiKey C Library Manual and it's about ykparse — the little tool that pops open a YubiKey OTP and shows you what's hiding inside 👀🔓

💖 NAME 💖

ykparse — decrypt and show information inside a YubiKey OTP 🎀

🌸 SYNOPSIS 🌸

ykparse AESKEY TOKEN

like. that's it. two lil args and you're in 🫶

🦋 DESCRIPTION 🦋

Decrypt and display information inside a YubiKey OTP. that's the whole vibe. it takes your key, it takes your token, and it spills the tea on what's actually encoded in there 💅✨

💜 OPTIONS 💜

• AESKEY — the 16-character AES-128 key you're gonna use, written out in hex. sixteen. characters. in hex. not sixteen hex chars, sixteen characters of hex, bestie, count them 😭
• TOKEN — the One-Time Password (OTP), and it's gotta be modhex encoded. modhex, not hex. different alphabet. don't mix them up or it's giving error energy 💀

🎀 EXAMPLES 🎀

the classic, the iconic, the typical usage of the tool is literally this:

ykparse ecde18dbe76fbd0c33330f1c354871db dteffujedcflcindvdbrblehecuitvjkjevvehjd

see how the first one is hex hex hex and the second one is modhex modhex modhex? yeah. that's the assignment. copy it, run it, slay 💅🔥

⭐ SEE ALSO ⭐

YubiKeys can be obtained from Yubico: http://www.yubico.com/ — go get you one, they're lowkey iconic 👑

heads up bestie: that AESKEY is a real secret key. treat it like your notes app password. no sharing, no screenshots, no posting it in the group chat 🙈
