*
|
|
* 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 http://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.
