 NTLM is an authentication protocol used in various Microsoft network
 protocol implementations and supported by the NTLM Security Support
 Provider ("NTLMSSP"). Originally used for authentication and negotiation
 of secure DCE/RPC, NTLM is also used throughout Microsoft's systems as
 an integrated single sign-on mechanism.
 .
 NTLM employs a challenge-response mechanism for authentication, in which
 clients are able to prove their identities without sending a password to
 the server. It consists of three messages, commonly referred to as Type 1
 (negotiation), Type 2 (challenge) and Type 3 (authentication).
