SIGSUM-KEY-TO-HASH(1)

💅 SIGSUM-KEY-TO-HASH — the manual, but make it cute

okay bestie, quick vibe check: this is sigsum-key-to-hash, section 1, part of the User Commands lineup. it's the glow-up move where you take a public key and turn it into a shiny hex hash. no cap, that's the whole plot. let's get into it 🫶

✨ NAME ✨

sigsum-key-to-hash — output public-key hash in hex format 💖

---

🌸 SYNOPSIS 🌸

sigsum-key to-hash [--help] [-k key-file] [-o output-file]

---

🦋 DESCRIPTION 🦋

so here's the tea: this tool reads a public key in OpenSSH format and spits out its hash in hex format. iconic behavior honestly.

by default the public key comes in on stdin, and the output goes out on stdout — very lowkey, very standard. 🎀

wanna override that default behavior? literally just use the -k and -o options and you're the main character now. 🔥

---

👑 OPTIONS 👑

• --help — show the usage message and then dip (exit). that's it, that's the option. 💁
• -k, --key=key-file — your public key in OpenSSH format. feed it the key-file and let it cook. 🔑
• -o, --output=output-file — the hashed public key in hex format goes here. output-file, we're sending you on a mission bestie ✨

💀 RETURN CODES 💀

a non-zero return code means failure. if it's zero, you ate and left no crumbs. anything else? not slay, something went wrong. 😭
