Hash

The hash icon represents a cryptographic hash function, a one-way mathematical algorithm that takes input data of any size and produces a fixed-size string of characters. This hash value serves as a digital fingerprint, ensuring data integrity and authenticity. Hash functions are widely used in computer science and cryptography.

In software development, hash icons are often used in blockchain and cryptocurrency applications, such as Coinbase, Binance, and KuCoin, to represent data integrity and security. For example, hash functions are used to secure transactions and control the creation of new units.

From a UX perspective, the hash icon communicates data security and authenticity, helping users understand that their data is protected. It can be used to indicate that data has been verified or validated, providing a sense of trust and reliability.

Hash is one of 824 icons in Pico-icon, made by Picon Contributors and released under Open Font License. It is drawn on a 8 × 8 grid.

Sign in (it's free), then open Get icon, Install with shadcn CLI, and pick your package manager to copy the command. It adds HashIcon to components/icons/picon-hash.tsx: one file, a size prop (24 by default) and every SVG prop, with no icon package.

Copy it as React (from Get icon, or the Code section): a typed HashIcon component you paste into your project, with no package to install. Only the icons you import reach your bundle. It works in Next.js and any React app.

Open Get icon, then Copy as code, and pick Vue, Svelte, Angular, Solid or Preact; the Code section shows each one too. Every version is one self-contained component with the SVG inside, and SVG and data URL copies are there for plain HTML and CSS.

With Pro, the shadcn.io MCP server lets Claude Code, Cursor or any MCP client find the Hash icon, or any of 824 Pico-icon icons, and install it from a prompt.

It's drawn in currentColor, so it takes the text color wherever you use it: a class like text-primary recolors it. To bake a color in, set one in Customize before you copy.

Set width and height on the component, or a class like size-6. It's drawn on a 8 × 8 grid, so it stays sharp at any size. Customize also sets the size it exports at, its padding and rotation.

Yes. It follows the text color, so with text-foreground (or any theme token) it changes with your light and dark themes. The icon is a vector, so it needs no separate dark asset.

Next to a visible label it's decoration: add aria-hidden="true" so screen readers skip it. Standing alone, as in an icon button, give the button a name instead, like aria-label="Hash", so screen readers say what it does.

Yes. HashIcon passes every SVG prop to the svg element, so <HashIcon aria-hidden="true" /> works, and so do role="img" with aria-label, or a title child, when it carries meaning on its own.

Yes. Open Get icon, then Download file: SVG for code or design tools like Figma; PNG, WebP or JPEG at 512px; or an ICO favicon with 16, 32 and 48px inside. Each one uses what you set in Customize.

Yes. The Open Font License allows commercial use; the icons can't be sold on their own. The full terms are in the license, linked on this page.

No visible credit is required: Open Font License only asks that you keep the license notice if you ship the icons' source files. Icons installed with the shadcn CLI already start with a comment naming Pico-icon, Picon Contributors and the license.

Yes. Copying and downloading it is free, and the shadcn CLI install only needs a free account.

8 other libraries draw an icon called Hash. The Other libraries section on this page shows each one, so you can compare them and open the one that fits your style.

Its tags are security, data, cryptocurrency, blockchain, algorithm and integrity. Each tag page lists the icons that carry it from every library, which is the quickest way to find a match for Hash in another set.
