Cipher Input | Sean Lynch

Made of something. Used blackened steel around a recessed phosphor screen. Short scratches, edge wear and a small mechanical return key.

The moment. Submission scans while the caller validates. Accepted or denied replaces the displayed value; editing restores the original input. Stale requests are cancelled.

Yours to adapt. Copy the component source, styles and materials. Functional text stays live, effects respect reduced motion, and the artwork requires no remote hosting.

Try it

Enter a code and submit to try the demonstration validation.

Install

Add it with the shadcn CLI, or copy the source manually.

Release candidate: public installation becomes available after deployment. Use an existing React 19 project with shadcn initialized and a components.json file. The CLI installs the source, CSS, embedded materials, MIT licence and font notices together.

Terminal

npx shadcn@latest add https://seanportfol.io/r/grimkit-cipher-input.json

Prefer a namespace? Register the registry once.

Terminal

npx shadcn@latest registry add @seanlynch=https://seanportfol.io/r/{name}.json

Terminal

npx shadcn@latest add @seanlynch/grimkit-cipher-input

Usage

Copy this example into a separate file, not over the installed component. The @/ alias points to your source root. In Next.js this is a Client Component; Vite also accepts the directive. Replace demonstration actions with your application logic.

components/examples/cipher-input-demo.tsx

"use client";

import { CipherInput } from "@/components/grimkit/cipher-input";

export default function Example() {
  // Demonstration only. Real authorization must run on your server.
  return <CipherInput label="Access code" hint="Try VIGIL-7" onVerify={(value) => ({
    accepted: value.trim().toUpperCase() === "VIGIL-7",
    message: value.trim().toUpperCase() === "VIGIL-7" ? "Clearance accepted." : "Clearance denied.",
  })} />;
}
