Free SSH Public Key QR Code Generator
Paste your SSH public key (id_ed25519.pub or id_rsa.pub) and get a scannable QR. Beats typing the key by hand on a fresh machine.

- SSH client apps (Termius, ServerCat) that support ssh:// URIs.
- When not to use
- For scanning private keys — keys should never leave the origin device.
- Standards
- ssh:// URI scheme (de facto).
- QR-generator
- Gratis visittkortdesigner
- Utskrivbare WiFi-kort
- Batch CSV (500 koder)

Kompatibilitetsforklaring
Dette strekkodeformatet rendres monokromt med bare forgrunns- og bakgrunnsfarger. Maler, prikk-/øyeformer, gradienter, rammer og sentrumslogoer gjelder kun QR-koder og er skjult her.

Rendres bak QR-en med redusert opasitet. Tvinger automatisk EC=H slik at QR-en fortsatt skanner gjennom bildet.
Batchgenerering
Last opp en CSV for å generere opptil 500 QR-koder i én batch. Hver rad blir sin egen QR — velg en mal eller overstyr 21 egenskaper per rad: farger, rammer, prikk/øye/øyeeple-stiler, gradienter, gjennomsiktighet, størrelse, feilkorrigering, format, innebygd logo og mer.
21 kolonner: type, data, filename, frametext, frame, template, fgcolor, bgcolor, size, ec, dotstyle, eyestyle, format, logo, gradient, g2, gtype, gangle, transparent, eyeball, eyecolor. Kun type og data kreves. Bruk | for å skille felt inne i data (f.eks. ssid|password|WPA).
Alle 20 QR-typer støttes, inkludert URL, WiFi, vCard, MeCard, Email, SMS, Event, Location, UPI, SEPA, PayPal, Crypto, Micro QR og rMQR. Last ned eksempel-CSV for å se hver kolonne, alle 40 maler, 11 rammestiler og de 12 innebygde logoene i aksjon.

Why scan an SSH key?
The pain point: you're setting up a new server, a new VM, a Raspberry Pi, an embedded device — and you need to drop your SSH public key into ~/.ssh/authorized_keys so you can stop typing the password. Copy/paste from your laptop is awkward when the new machine has no clipboard, and typing 80+ random characters by hand is asking for typos. Scan a QR with any QR scanner that pipes to clipboard, paste, done.
Abundera QR encodes the entire one-line public key — the key type, the base64-encoded key body, and the optional comment — verbatim. There's no algorithm magic here, just text-in/text-out. The key type prefix tells the scanner what to do with it.
Privacy
SSH public keys are public by design — sharing them does not compromise security. The matching private key (which you should never paste into anything, ever) stays on your laptop. Abundera QR processes the public key entirely in your browser; nothing leaves the page.

Frequently Asked Questions
Does this encode my private key?
No. Only the public key. Pasting your private key into any web tool, ours included, is a bad idea. Public keys (the part you put in authorized_keys, the one starting with ssh-ed25519 / ssh-rsa / ecdsa-sha2-...) are safe to share.
What key types are supported?
Any text-format public key: ssh-ed25519, ssh-rsa, ssh-dss (legacy), ecdsa-sha2-nistp256/384/521, sk-ssh-ed25519@openssh.com, sk-ecdsa-sha2-nistp256@openssh.com (FIDO2 hardware keys). The QR is just text — it works for whatever format you paste.
How big can the key be?
Standard QR codes max out around 2,953 alphanumeric characters or 4,296 numeric. An ed25519 public key is ~80 chars and fits comfortably. RSA-4096 keys are ~700 chars, also fine. RSA-8192 keys can push the QR into the dense end of version 40 — they'll still scan but only at large print sizes.
Can I encode multiple keys in one QR?
Yes — paste multiple authorized_keys lines separated by newlines. The QR will contain all of them and scanning will dump the whole block.
Does the recipient need a special app?
No. Any QR scanner that puts the result on the clipboard works — the iPhone camera, Android camera, Google Lens, our own scanner mode. Then paste into a terminal.
Is this related to ssh-add or ssh-keygen?
Not directly. We just encode the text you paste. Generate the keypair locally with ssh-keygen, copy the contents of id_ed25519.pub, paste here, and you have a portable QR.
Can I use this for git deploy keys?
Yes — same format. Encode your deploy public key, scan it on the server, drop it into the deploy account's authorized_keys.
