Is this safe to use with sensitive data?
Yes — hashing runs entirely in your browser via the built-in Web Crypto API. Your input never leaves your machine.
Why is MD5 not included?
MD5 is cryptographically broken and should not be used for security purposes. Use SHA-256 or SHA-512 instead.
Can I hash a file?
Yes — click \"Hash a file…\" and pick any file up to 100 MB. It is hashed locally with the Web Crypto API and never uploaded.
