SHA-256 Generator
The right default for integrity checks today. The digest is produced by the browser crypto layer, not by a re-implementation in page script.

Frequently Asked Questions
Which algorithms run natively?
SHA-1, SHA-256, SHA-384 and SHA-512 use the browser SubtleCrypto API. MD5 is computed by a local implementation because browsers do not expose it.
Can I use these hashes to protect passwords?
No. A plain hash is not a password storage mechanism — MD5 and SHA-1 are broken for signatures, and fast hashes are brute-forced quickly. Use bcrypt, scrypt or Argon2 in your application.
Why does SHA-256 sometimes not work?
SubtleCrypto is only available in a secure context, meaning HTTPS or localhost. Over plain HTTP the browser hides it and the tool says so instead of returning a fake digest.
