This tool runs open-source code from CyberChef by GCHQ (Apache License 2.0). See open-source credits.

NT Hash Calculator uses NT Hash Calculator for the supplied input. It returns the MD4 digest of UTF-16LE password bytes. This is not an NTLM challenge-response message.

It returns the MD4 digest of UTF-16LE password bytes. This is not an NTLM challenge-response message. This result runs in the browser for this catalog category. Processing runs in the browser.

This operation reports a digest or checksum; it does not provide encryption, identity, or complete application security.

Instructions

  1. Provide text or data for this tool.
  2. Enter password without a newline for the fixture. This applies to NT Hash Calculator.
  3. Do not pre-encode the text as hexadecimal unless you first decode those bytes. This applies to NT Hash Calculator.

Example

Input: Use text "password"; the NT hash is 8846F7EAEE8FB117AD06BDD830B7586C.

Settings: NT Hash Calculator: Input is text; the implementation converts code units to UTF-16LE before MD4. The output uses uppercase hexadecimal and exposes no salt or cost setting.

Result: It returns the MD4 digest of UTF-16LE password bytes. This is not an NTLM challenge-response message.

Limits

  • NT Hash Calculator: Fast unsalted password hashing does not provide modern password-storage protection.
  • NT Hash Calculator: This tool neither authenticates to Windows nor checks account permissions.

Questions

What input does NT Hash Calculator accept?

NT Hash Calculator accepts text. An NT Hash, sometimes referred to as an NTLM hash, is a method of storing passwords on Windows systems. It works by running MD4 on UTF-16LE encoded input. NTLM hashes are considered weak because they can be brute-forced very easily with modern hardware.

Does NT Hash Calculator need extra settings?

NT Hash Calculator does not define extra operation settings. It uses its built-in behavior with the supplied input.

What does NT Hash Calculator return?

NT Hash Calculator returns text. An NT Hash, sometimes referred to as an NTLM hash, is a method of storing passwords on Windows systems. It works by running MD4 on UTF-16LE encoded input. NTLM hashes are considered weak because they can be brute-forced very easily with modern hardware.
