NTLM hash calculator

NTLM hash and this calculator

The NTLM hash refers to the hashed version of a user’s plain password that is used for authentication using NTLM protocol (see below). Instead of transmitting the actual password over the network, NTLM uses a hash to verify a user's identity, which helps protect the password from being exposed during the authentication process. This online NTLM hash generator is designed to help you calculate the NTLM hash of any string you enter.

What is NTLM?

NTLM (NT LAN Manager) is a family of authentication protocols used in Microsoft networks for authenticating clients and servers. It has been widely used in various Microsoft operating systems since the release of Windows NT.

NTLM and Modern Security Practices

While NTLM is still used for backward compatibility, modern systems and networks use more secure authentication mechanisms such as Kerberos, OAuth, and SAML. These protocols offer stronger encryption, better support for multi-factor authentication, and fewer vulnerabilities compared to NTLM.

NTLM remains an important part of legacy Microsoft systems and networks, but it is increasingly considered insecure. Modern systems should use more secure alternatives like Kerberos for authentication, and NTLM should only be used in situations where it’s absolutely necessary
