Perguntas frequentes
›Which hash algorithms are supported?
SHA-1, SHA-256, SHA-384 and SHA-512 via the Web Crypto API. MD5 is intentionally omitted — it's broken for security use.
›Is my input sent anywhere?
No. Hashing runs in your browser using the native Web Crypto API.
›Why no MD5?
MD5 has been cryptographically broken since 2004 — collisions can be generated trivially. Use SHA-256 or stronger.
›What about SHA-3?
SHA-3 isn't available in the Web Crypto API yet. SHA-256 is still the standard recommendation for new projects.
›Are hashes reversible?
No — that's the point. Hashes are one-way. To 'crack' a hash you'd need to brute-force the input, which is infeasible for strong inputs.
›Is the generator free?
Yes — fully free, no signup.
