Hash any text
Type or paste text and all four SHA digests update live. SHA-1 is included for legacy checksums only — it is no longer collision-safe.

When NOT to use Hash Generator
- SHA-1 is collision-broken — it is included for legacy checksums only; use SHA-256 or stronger for anything security-related.
- Never hash passwords with fast general-purpose hashes like SHA-256 for storage — password storage needs a slow KDF such as bcrypt, scrypt, or Argon2.
Questions people ask
Is my input sent to a server?
No. This tool runs entirely in your browser using JavaScript. Nothing you paste is uploaded, stored, or sent anywhere.
Which algorithms are available?
SHA-1, SHA-256, SHA-384, and SHA-512 — all computed with the browser's built-in Web Crypto API, the same implementations used by production software.
Is a hash the same as encryption?
No. Hashing is one-way: you cannot recover the text from the digest. It is used for integrity checks and fingerprinting, not for keeping data secret.
