NTLM (NT LAN Manager) uses MD4 applied to the UTF-16 little-endian encoding of the password. It is used in Windows authentication. This tool computes the NTLM hash entirely in your browser using a pure-JavaScript MD4 implementation — nothing is sent to a server.
Cryptographic hashing is a foundational technique in security, data integrity verification, and authentication systems. The NTLM Hash is Generate NTLM hash (MD4 of UTF-16LE) for any string — and it runs entirely in your browser with no data sent to any server. Whether you are a developer, data analyst, student, or technical user, this free tool removes friction from your workflow and gives you instant, accurate results every time. If you need to take the output a step further, try the MySQL Password Hash — it handles the next stage of the workflow.
The NTLM Hash is a free, browser-based utility that generate ntlm hash (md4 of utf-16le) for any string. It processes your input locally using JavaScript, which means all operations happen on your device — no uploads, no server processing, and no privacy concerns. The result is immediate, updating as you interact with the tool. Alternatively, if you are looking for something slightly different, the Bcrypt Generator may be a better fit.
Tools like this are used every day by web developers, DevOps engineers, data scientists, security professionals, and content creators. The NTLM Hash belongs to this class of essential utilities that save time, reduce errors, and streamline everyday technical tasks.
There are many generic tool sites online, but the NTLM Hash on Chunky Munster is built with a developer-first mindset. Everything runs in your browser — there are no paywalls, no rate limits, no forced sign-ups, and no advertisements disrupting your concentration. For related work, the MD5 Hash Calculator is another popular tool worth bookmarking.
The NTLM Hash generates a fixed-length hash from any input using a specific cryptographic algorithm. The result is deterministic — the same input always produces the same hash.
No. Cryptographic hashes are one-way functions. It is computationally infeasible to reverse a hash back to its original input.
General-purpose hash functions like MD5 or SHA-256 are not suitable for password storage by themselves. For passwords, use bcrypt, Argon2, or scrypt which are specifically designed to be slow and resistant to brute force.
Yes — completely free, browser-based, and your data never leaves your device.
