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.

◆ 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).

◆ getNegotiate()

bool KNTLM::getNegotiate ( QByteArray negotiate,

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.
