SIGSUM-KEY-FROM-HEX(1)

💖 SIGSUM-KEY-FROM-HEX 💖

okay bestie, so there's this command called sigsum-key-from-hex, and literally all it does is take a public key that's chillin' in hex format and turn it into OpenSSH format ✨ that's it. that's the whole job. she's a converter, she's an icon, she's not complicated 🎀

(also yes the page is called sigsum-key-from-hex but you actually type it as sigsum-key from-hex — the hyphenated name is just the manpage's government name, iykyk 💅)

---

🌸 SYNOPSIS 🌸

sigsum-key from-hex [--help] [-k key-file] [-o output-file]

---

🦋 DESCRIPTION 🦋

so the vibe is: she reads a public key in hex format, and she prints it back out in OpenSSH format. periodt 💜

by default the public key gets read from stdin and the output gets written to stdout. classic pipes-and-redirects situation, very demure, very mindful 🌈

but if you wanna switch it up? the -k and -o options let you override that default behavior. you do you, queen 👑

---

✨ OPTIONS ✨

• --help — shows you the usage message and then dips. that's it, that's all 🫶
• -k, --key=key-file — this is where you point at your public key in hex format. like, "here's the hex key bestie, handle it" 🍓
• -o, --output=output-file — and this one says where the public key in OpenSSH format should land 📁

---

💀 RETURN CODES 💀

if something goes wrong, she hits you with a non-zero return code. non-zero = it did not slay, it failed. no cap 😭
