NTLMv2
- -U --user

- -K
--session-key
- Session Key
- -R --response
- response type space separated: lm ntlm lm2 ntlm2 ntlm2-session
- -u --unicode
- transmit user, workstation, ... as unicode strings
- -f --flags
- Space separated NTLM flags neg-unicode:
- Indicates that
Unicode strings are
- supported for use in security buffer data.
- neg-oem:
- Indicates that OEM strings are supported for use in security buffer
data.
- req-target:
- Requests that the server's authentication realm be included in the Type 2
message.
- neg-sign:
- Specifies that authenticated communication between the client and server
should carry a digital signature (message integrity).
- neg-seal:
- Specifies that authenticated communication between the client and server
should be encrypted (message confidentiality).
- neg-datagram-style:
- Indicates that datagram authentication is being used.
- neg-lm-key:
- Indicates that the Lan Manager Session Key should be used for signing and
sealing authenticated communications.
- neg-netware:
- This flag's usage has not been identified.
- neg-ntlm-key:
- Indicates that NTLM authentication is being used.
- neg-anonymous:
- Sent by the client in the Type 3 message to indicate that an anonymous
context has been established. This also affects the response fields.
- neg-domain-supp:
- Sent by the client in the Type 1 message to indicate that the name of the
domain in which the client workstation has membership is included in the
message. This is used by the server to determine whether the client is
eligible for local authentication.
- neg-workstation-supp:
- Sent by the client in the Type 1 message to indicate that the client
workstation's name is included in the message. This is used by the server
to determine whether the client is eligible for local authentication.
- neg-local-call:
- Sent by the server to indicate that the server and client are on the same
machine. Implies that the client may use the established local credentials
for authentication instead of calculating a response to the
challenge.
- neg-always_sign:
- Indicates that authenticated communication between the client and server
should be signed with a "dummy" signature.
- target-type-domain:
- Sent by the server in the Type 2 message to indicate that the target
authentication realm is a domain.
- target-type-server:
- Sent by the server in the Type 2 message to indicate that the target
authentication realm is a server.
- target-type-share:
- Sent by the server in the Type 2 message to indicate that the target
authentication realm is a share. Presumably, this is for share-level
authentication. Usage is unclear.
- neg-ntlm2-key:
- Indicates that the NTLM2 signing and sealing scheme should be used for
protecting authenticated communications. Note that this refers to a
particular session security scheme, and is not related to the use of
NTLMv2 authentication. This flag can, however, have an effect on the
response calculations
- req-init-res:
- This flag's usage has not been identified
- req-accept-res:
- This flag's usage has not been identified
- req-nonnt-session-key:
- This flag's usage has not been identified
- neg-target-info:
- Sent by the server in the Type 2 message to indicate that it is including
a Target Information block in the message. The Target Information block is
used in the calculation of the NTLMv2 response.
- neg-128:
- Indicates that 128-bit encryption is supported.
- neg-key-exchange:
- Indicates that the client will provide an encrypted master key in the
"Session Key" field of the Type 3 message.
- neg-56:
- Indicates that 56-bit encryption is supported.
