⚠️ Security Notice
- NTLM hashes are used for Windows authentication protocols
- Never transmit actual NTLM hashes over insecure networks
- This tool is for testing and educational purposes only
- Modern systems should use NTLMv2 or Kerberos instead
Convert any password to an NTLM hash locally in your browser. Zero data sent to any server.
NTLM (NT LAN Manager) is a Microsoft authentication protocol that stores passwords as MD4-hashed values. Whether you're a sysadmin testing Active Directory configurations, a penetration tester verifying hash outputs, or a developer working with Windows authentication systems, having a reliable NTLM hash generator is essential.
Our NTLM Hash Generator runs entirely in your browser using client-side JavaScript — meaning your password input never touches a server. It's the safest way to generate NTLM hashes online, with no logging, no storage, and no risk of credential exposure.
NTLM hashes are used by Windows operating systems to store and verify user passwords in Active Directory and local authentication. They are also commonly used in penetration testing and security research to verify authentication flows without exposing plaintext passwords.
With UtilDash, yes — completely. Our tool processes everything locally in your browser using JavaScript. Your password is never transmitted to any server, making it as safe as running the hash generation on your own machine.
NTLM uses the MD4 algorithm (not MD5) applied to the UTF-16LE encoded password. While both produce fixed-length hashes, they use different algorithms and are not interchangeable. NTLM is specifically used in Windows authentication systems.
Yes. Security professionals commonly use NTLM hash generators to verify hash outputs during authorized penetration tests. Always ensure you have explicit permission before testing any system.
Yes. NTLM hashing is based on the UTF-16LE encoding of the password, and our tool fully supports Unicode characters including special symbols and non-Latin characters.
All processing happens locally in your browser. We never see, store, or transmit your data. This tool is fully client-side and secure.
