Field Detail

ANONYMOUS

public static final NtlmPasswordAuthentication ANONYMOUS

Constructor Detail

NtlmPasswordAuthentication

public NtlmPasswordAuthentication(java.lang.String userInfo)

Create an NtlmPasswordAuthentication object from the userinfo component of an SMB URL like "domain;user:pass". This constructor is used internally be jCIFS when parsing SMB URLs.

NtlmPasswordAuthentication

public NtlmPasswordAuthentication(java.lang.String domain,
                                  java.lang.String username,
                                  java.lang.String password)

Create an NtlmPasswordAuthentication object from a domain, username, and password. Parameters that are null will be substituted with jcifs.smb.client.domain, jcifs.smb.client.username, jcifs.smb.client.password property values.

NtlmPasswordAuthentication

public NtlmPasswordAuthentication(java.lang.String domain,
                                  java.lang.String username,

                                  byte[] ansiHash,
                                  byte[] unicodeHash)

Create an NtlmPasswordAuthentication object with raw password hashes. This is used exclusively by the jcifs.http.NtlmSsp class which is in turn used by NTLM HTTP authentication functionality.

Method Detail

getPreNTLMResponse

public static byte[] getPreNTLMResponse(java.lang.String password,
                                        byte[] challenge)

Generate the ANSI DES hash for the password associated with these credentials.

getNTLMResponse

public static byte[] getNTLMResponse(java.lang.String password,
                                     byte[] challenge)

Generate the Unicode MD4 hash for the password associated with these credentials.

getLMv2Response

public static byte[] getLMv2Response(java.lang.String domain,
                                     java.lang.String user,
                                     java.lang.String password,
                                     byte[] challenge,
                                     byte[] clientChallenge)

Creates the LMv2 response for the supplied information.

Parameters:

domain - The domain in which the username exists.

user - The username.

password - The user's password.

challenge - The server challenge.

clientChallenge - The client challenge (nonce).

getNTLM2Response

public static byte[] getNTLM2Response(byte[] nTOWFv1,
                                      byte[] serverChallenge,
                                      byte[] clientChallenge)

nTOWFv1

public static byte[] nTOWFv1(java.lang.String password)

                                       byte[] targetInfo)

getDomain

public java.lang.String getDomain()

Returns the domain.

getUsername

public java.lang.String getUsername()

Returns the username.

getPassword

public java.lang.String getPassword()

Returns the password in plain text or null if the raw password hashes were used to construct this NtlmPasswordAuthentication object which will be the case when NTLM HTTP Authentication is used. There is no way to retrieve a users password in plain text unless it is supplied by the user at runtime.

getName

public java.lang.String getName()

Return the domain and username in the format: domain\\username. This is equivalent to toString().

Specified by:

getName in interface java.security.Principal

getAnsiHash

public byte[] getAnsiHash(byte[] challenge)

Computes the 24 byte ANSI password hash given the 8 byte server challenge.

getUnicodeHash

public byte[] getUnicodeHash(byte[] challenge)

Computes the 24 byte Unicode password hash given the 8 byte server challenge.

getSigningKey

public byte[] getSigningKey(byte[] challenge)
                     throws SmbException

Throws:

SmbException

getUserSessionKey

public byte[] getUserSessionKey(byte[] challenge)

Returns the effective user session key.

Parameters:

challenge - The server challenge.

Returns:

A byte[] containing the effective user session key, used in SMB MAC signing and NTLMSSP signing and sealing.

equals

public boolean equals(java.lang.Object obj)

Compares two NtlmPasswordAuthentication objects for equality. Two NtlmPasswordAuthentication objects are equal if their caseless domain and username fields are equal and either both hashes are external and they are equal or both internally supplied passwords are equal. If one NtlmPasswordAuthentication object has external hashes (meaning negotiated via NTLM HTTP Authentication) and the other does not they will not be equal. This is technically not correct however the server 8 byte challage would be required to compute and compare the password hashes but that it not available with this method.

Specified by:

equals in interface java.security.Principal

Overrides:

equals in class java.lang.Object

hashCode

public int hashCode()

Return the upcased username hash code.

Specified by:

hashCode in interface java.security.Principal

Overrides:

hashCode in class java.lang.Object

toString

public java.lang.String toString()

Return the domain and username in the format: domain\\username. This is equivalent to getName().

Specified by:

toString in interface java.security.Principal

Overrides:

toString in class java.lang.Object
