Generate SHA-1, SHA-256, SHA-384, and SHA-512 hashes of any text or file. Computed locally with the browser's Web Crypto API.
Type or paste text — or drop in any file — to compute four hashes at once: SHA-1, SHA-256, SHA-384, and SHA-512. Output is rendered in lowercase hex by default; toggle “Uppercase” to switch case. Each row has its own copy button.
Hashes are computed in the browser via Web Crypto’s crypto.subtle.digest, so neither your text nor your files ever leave your device.
