Hash Generator

SHA-256, SHA-512 and SHA-1 hashes for any text — computed in your browser.

FREE TOOL · WORKS OFFLINE · NO SIGN-UP

Hashes update as you type (with a short delay so long pastes stay smooth).

SHA-256 (64 hex chars)

SHA-512 (128 hex chars)
—
SHA-1 (40 hex chars)

MD5 is intentionally not offered: it is broken for security use, and the browser's built-in crypto API does not provide MD5.

🔐 How to Use This Hash Generator

  1. 1.Type or paste any text. All three hashes update automatically — try "abc" and compare with any reference table.
  2. 2.Pick the hash you need. SHA-256 is the everyday standard; SHA-512 is its longer, stronger sibling; SHA-1 is shown only for legacy checks and should not be used for security.
  3. 3.Copy with one tap. Each hash has its own Copy button for pasting into a checksum check or a verification step.
  4. 4.Verify a file or password safely. Hashing the same text twice always gives the same result, so a matching hash proves the content is unchanged.
  5. 5.Nothing leaves your browser. Hashing uses the built-in WebCrypto API on your own device — no server ever sees your text.

❓ FAQ

What is a hash?

A hash is a fixed-length fingerprint of a piece of text. Change even one character and the hash changes completely, but the same text always produces the same hash. SHA-256 gives 64 hex characters, SHA-512 gives 128, and SHA-1 gives 40.

Why is MD5 not included?

MD5 is intentionally omitted. It is broken and unsafe for security use, and the browser's built-in crypto API does not offer MD5 at all. Rather than ship a slow, unsafe JavaScript MD5, this tool sticks to the secure hashes your browser provides natively.

Is my text uploaded anywhere?

No. Hashing runs entirely in your browser using the WebCrypto API. Your text never leaves this page, is never sent to a server, and is never saved or tracked.

Is this hash generator free?

Yes — 100% free, no sign-up. Generate as many hashes as you like, for any text, at no cost.
