Detailed Description

KNTLM class implements the NTLM authentication protocol.

The KNTLM class is useful for creating the authentication structures which can be used for various servers which implements NTLM type authentication. A comprehensive description of the NTLM authentication protocol can be found at https://davenport.sourceforge.net/ntlm.html The class also contains methods to create the LanManager and NT (MD4) hashes of a password. This class doesn't maintain any state information, so all methods are static.

Member Function Documentation

getAuth()

bool KNTLM::getAuth ( QByteArray &  auth, const QByteArray &  challenge, const QString &  user, const QString &  password, const QString &  domain = QString(), const QString &  workstation = QString(), AuthFlags  authflags = Add_LM  )

static

Creates the type 3 message which should be sent to the server after the challenge (type 2) received.

Parameters

auth	- a buffer where the Type 3 message will returned.
challenge	- the Type 2 message returned by the server.
user	- user's name.
password	- user's password.
domain	- the target domain. If left NULL (i.e. QString()), it will be extracted from the challenge. If set to an empty string (QString("")) an empty domain will be used.
workstation	- the user's workstation.
authflags	- AuthFlags flags that changes the response generation behavior. Force_V1 or Force_V2 forces (NT)LMv1 or (NT)LMv2 responses generation, otherwise it's autodetected from the challenge. Add_LM adds LMv1 or LMv2 responses additional to the NTLM response.

Returns

true if auth filled with the Type 3 message, false if an error occurred (challenge data invalid, NTLMv2 authentication forced, but the challenge data says no NTLMv2 supported, or no NTLM supported at all, and Add_LM not specified).

Deprecated:

Since 5.91, no known users.

getLMResponse()

QByteArray KNTLM::getLMResponse ( const QString &  password, const unsigned char *  challenge  )

static

Returns the LanManager response from the password and the server challenge.

Deprecated:

Since 5.91, no known users.

Definition at line 298 of file kntlm.cpp.

getLMv2Response()

QByteArray KNTLM::getLMv2Response ( const QString &  target, const QString &  user, const QString &  password, const unsigned char *  challenge  )

static

Calculates the LMv2 response.

Deprecated:

Definition at line 379 of file kntlm.cpp.

getNegotiate()

bool KNTLM::getNegotiate ( QByteArray &  negotiate, const QString &  domain = QString(), const QString &  workstation = QString(), quint32  flags = Negotiate_Unicode | Request_Target | Negotiate_NTLM  )

static

Creates the initial message (type 1) which should be sent to the server.

Parameters

negotiate	- a buffer where the Type 1 message will returned.
domain	- the domain name which should be send with the message.
workstation	- the workstation name which should be send with the message.
flags	- various flags, in most cases the defaults will good.

Returns

true if creating the structure succeeds, false otherwise.

Deprecated:

Since 5.91, no known users.
