What is Hash Generator?
A hash function turns any text into a fixed-length, irreversible fingerprint. It's used to verify the integrity of a file or message, index content, or as part of secure password storage. This tool computes SHA-1, SHA-256, SHA-384 and SHA-512 in real time with the browser's native Web Crypto API.
Type the text and get all the fingerprints instantly, ready to copy. It's useful for comparing a checksum, generating a deterministic identifier, or checking that two inputs produce the same hash. All computation happens locally.
