SHA-256 Generator

What is SHA-256 Generator?

This SHA-256 generator produces a 256-bit digest (64 hexadecimal characters) for any text input using the browser native Web Crypto API. It is the recommended general-purpose hash today, suitable for integrity verification and for the hashing step of a signature scheme. All computation happens locally.

How to use SHA-256 Generator

1. 1Type or paste your text and the digest is generated instantly.
2. 2Toggle between uppercase and lowercase output.
3. 3Compare the result character by character against the officially published checksum.

How do I do this in code?

Use the tool above for one-off work; for anything you repeat, move it into a script or your project.

const sha256 = async (text) => {
  const buf = await crypto.subtle.digest('SHA-256', new TextEncoder().encode(text));
  return [...new Uint8Array(buf)].map((b) => b.toString(16).padStart(2, '0')).join('');
};
