Hash Generator

MD5, SHA-1, SHA-256 and SHA-512 hashes of text. Free, no sign-up, your text stays on your device.

🔒 100% private — processing happens in your browser. Nothing is uploaded.

How to use the hash generator

  1. Type or paste text — hashes update as you type.
  2. Optionally enter a secret key to get HMAC signatures.
  3. Copy the hash you need. For files, use File Checksum.

Hashes are short fingerprints of data used to check integrity, store password fingerprints, sign API requests and compare values without revealing them. This page computes MD5, SHA-1, SHA-256, SHA-384 and SHA-512 instantly using the Web Crypto API, plus HMAC variants for webhook and API signatures. MD5 and SHA-1 are shown for compatibility but should not be used for security anymore.
