Hash Generator (sha-256/512) Passo A Passo

Last reviewed: 2026-07-16

Hash Generator (SHA-256/512) funciona em tres passos: abrir a ferramenta, digitar ou colar seu texto, depois escolher um algoritmo e copiar o digest. Esta pagina detalha o que cada passo espera.

Passo 1 - abrir a ferramenta

Va ate Hash Generator (SHA-256/512). Nao e preciso instalar nada nem fazer login antes de comecar.

Passo 2 - digitar ou colar seu texto

Digite ou cole o texto que quer hashear na caixa; depois escolha SHA-1, SHA-256, SHA-384 ou SHA-512 no menu suspenso. O digest atualiza em tempo real abaixo enquanto voce digita.

Passo 3 - copiar o digest

Clique em Copy para pegar o digest hexadecimal resultante. O calculo do hash roda totalmente no navegador via a WebCrypto API - nada e enviado a um servidor.

MD5 nao esta disponivel aqui porque navegadores modernos o omitem por ser inseguro; use a ferramenta relacionada md5-converter para esse algoritmo especifico.

Why trust these tools

Ten-plus years of web tooling. The freetoolonline editorial team has shipped browser-based utilities since 2015. The goal has never changed: get you to a working output fast, without an install.
No install, no sign-up. Open a tool and get a working output in seconds - nothing to download and no account to create. Tools that need heavy processing run it on our service, so even a low-powered machine gets the job done.
Analytics stops at the page view. We measure which pages get visited, not what you type or upload inside a tool. There is nothing to sign in to and no profile is attached to your input.
Open-source core components. The processing engines underneath (libheif, libde265, pdf-lib, terser, clean-css, ffmpeg.wasm, and others) are public and audit-able. We link to each one in its tool page's footer.
Free, with or without ads. All tools are fully functional without sign-up. The Disable Ads button in the header is always available if you need a distraction-free run.
