Gerador de hash
Gere hashes SHA e MD5.
Type or paste text and generate cryptographic hashes. SHA-1/256/384/512 use the browser's Web Crypto API; MD5 is included as a legacy, non-secure option. Everything runs locally in your browser.
Recomenda-se SHA-256 ou mais forte. SHA-1 e MD5 não são seguros e são incluídos apenas por compatibilidade legada.
Sua entrada é processada localmente no navegador — nada é enviado, armazenado ou registrado.

Perguntas frequentes
Is my input sent to a server?
No. Everything runs locally in your browser — your input is never uploaded, stored or logged.
Which algorithm should I use?
Use SHA-256 or stronger for security. SHA-1 and MD5 are broken for security and are provided only for legacy compatibility.
Are hashes reversible?
No. Hashes are one-way. This tool also does not store anything — it runs entirely in your browser.
Is it really free?
Yes — free, with no signup and no limits.
