SHA-256 Hash Generator
Type or paste text and get its SHA-256 digest instantly. Hashing runs entirely in the browser, so nothing is sent anywhere.
About SHA-256
SHA-256 is the workhorse of the SHA-2 family — a 256-bit digest with no practical attacks. It is the default choice for integrity checks, signatures, content addressing and most things labeled "checksum" today.
Digests here are computed with the browser's WebCrypto API; MD5 runs locally in JavaScript, since WebCrypto dropped it. A hash is one-way: the same input always produces the same 256-bit digest, but the digest cannot be reversed back into the input. Text entered here never leaves the page.
