Free Online Hash Generator — MD5, SHA-1 & SHA-256

Compute MD5, SHA-1, and SHA-256 hashes from any text input instantly. UtilHub's Hash Generator runs the algorithms directly in your browser using the Web Crypto API — your input text never leaves your device. Use it to verify file integrity, generate checksums for data validation, create password hashes for testing, or compare hash outputs across different algorithms side by side. Simple, fast, and private.

How to use Hash Generator

  • Enter text into the input field.
  • View MD5, SHA-1, and SHA-256 hashes instantly.
  • Click "Copy" next to any hash to save it.

Features

  • Multiple algorithms — Generate MD5, SHA-1, SHA-256, and SHA-512 hashes simultaneously from the same input. Compare results side by side.
  • Real-time hashing — Hash output updates as you type, giving you instant feedback without needing to click a button.
  • 100% client-side — Uses the Web Crypto API to compute hashes locally. No text is sent to any server. Ever.
  • Input flexibility — Handles any Unicode text, including special characters, emojis, and multi-line strings.

Frequently Asked Questions

Which hash algorithm should I use?

It depends on your use case. SHA-256 is the current standard for security-sensitive applications like digital signatures and blockchain. SHA-1 is still used for non-security checksums but is cryptographically broken. MD5 is fast and widely used for file integrity checks and non-security checksums, but it's not safe for passwords or security purposes due to known collision vulnerabilities.

Is my text safe when generating hashes here?

Yes. All hashing is done in your browser using the Web Crypto API. Your text input never leaves your device and is not stored, logged, or transmitted anywhere. This is verifiable — you can disconnect from the internet after loading the page and the tool will continue to work.
