Hash Generator

Generate a SHA-1, SHA-256, or SHA-512 hash of any text using your browser's built-in crypto — nothing is uploaded.

How it works

  1. Type or paste text into the box.
  2. Pick an algorithm SHA-1, SHA-256, or SHA-512.
  3. Copy the hash which updates as you type.

Frequently asked questions

Why no MD5?

MD5 is cryptographically broken and isn't provided by the browser's native crypto API. SHA-256 is the modern default.

Is my text sent anywhere?

No — hashing uses the browser's SubtleCrypto API and never leaves your device.
