SIGSUM-KEY-VERIFY(1)

💖 SIGSUM-KEY-VERIFY(1) 💖

okay bestie, gather round, because this is sigsum-key-verify from the User Commands section and she is here to check your Ed25519 signatures. 💅

---

✨ NAME ✨

sigsum-key-verify — verify an Ed25519 signature 🦋

---

✨ SYNOPSIS ✨

sigsum-key verify [--help] [-k key-file] [-n namespace] [-s sig-file] <
msg

---

✨ DESCRIPTION ✨

So basically 💖 you're verifying an Ed25519 signature, and you're doing it with a given namespace. Not me explaining namespaces like it's a vibe check, but like — the namespaces used in the Sigsum system are these two icons:

• sigsum.org/v1/tree-leaf — for signed checksums 👑
• sigsum.org/v1/submit-token — for rate limiting ✨

And the default behavior? No namespace at all. Zero. None. She simply doesn't use one unless you tell her to. 🎀

The message you're verifying gets handed to her on stdin. So like, pipe it in, bestie, she's waiting. 🫶

---

✨ OPTIONS ✨

• --help — show the usage message and dip. That's it, that's the whole thing. 💅
• -k, --key=key-file — the public key, in OpenSSH format. This one is required, no cap, she will not run without it. 🔑
• -n, --namespace=namespace — the signature namespace, so you get proper domain separation. 🌈
• -s, --signature=sig-file — the signature, in hex format. Also required! Both of these are non-negotiable, bestie. 🌸

---

✨ RETURN CODES ✨

A non-zero return code means failure. That's the whole story — if it's not zero, something went sideways. 😭
