Hash Generator
SHA-1, SHA-256, SHA-384 and SHA-512 hashes of any text.
Hashes are computed locally with WebCrypto. Empty input hashes the empty string.

About the Hash tool
Type or paste text and get its SHA digests instantly, computed with the browser’s native WebCrypto API. Copy any digest with one click.
Hashes are one-way: same input always gives the same digest, but the digest reveals nothing about the input. Use SHA-256 or better for anything security-adjacent.
Everything runs locally in your browser: no data is uploaded, no account is needed, and it works offline once the page has loaded.
