Class NtlmPasswordAuthentication
public final
class
NtlmPasswordAuthentication
extends Object
implements Principal, Serializable
This class stores and encrypts NTLM user credentials. The default
credentials are retrieved from the
jcifs.smb.client.domain,
jcifs.smb.client.username, and
jcifs.smb.client.password
properties.
Read jCIFS Exceptions and
NtlmAuthenticator for related information.
Constructor Summary |
| NtlmPasswordAuthentication(String userInfo)
Create an NtlmPasswordAuthentication object from the userinfo
component of an SMB URL like "domain;user:pass". |
| NtlmPasswordAuthentication(String domain, String username, String password)
Create an NtlmPasswordAuthentication object from a
domain, username, and password. |
| NtlmPasswordAuthentication(String domain, String username, byte[] challenge, byte[] ansiHash, byte[] unicodeHash)
Create an NtlmPasswordAuthentication object with raw password
hashes. |
Method Summary |
boolean | equals(Object obj)
Compares two NtlmPasswordAuthentication objects for
equality. |
byte[] | getAnsiHash(byte[] challenge)
Computes the 24 byte ANSI password hash given the 8 byte server challenge. |
String | getDomain()
Returns the domain. |
static byte[] | getLMv2Response(String domain, String user, String password, byte[] challenge, byte[] clientChallenge)
Creates the LMv2 response for the supplied information.
|
String | getName()
Return the domain and username in the format:
domain\\username. |
static byte[] | getNTLMResponse(String password, byte[] challenge)
Generate the Unicode MD4 hash for the password associated with these credentials. |
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. |
static byte[] | getPreNTLMResponse(String password, byte[] challenge)
Generate the ANSI DES hash for the password associated with these credentials. |
byte[] | getUnicodeHash(byte[] challenge)
Computes the 24 byte Unicode password hash given the 8 byte server challenge. |
String | getUsername()
Returns the username. |
byte[] | getUserSessionKey(byte[] challenge)
Returns the effective user session key.
|
int | hashCode()
Return the upcased username hash code. |
String | toString()
Return the domain and username in the format:
domain\\username. |
public NtlmPasswordAuthentication(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.
public NtlmPasswordAuthentication(String domain, String username, 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.
public NtlmPasswordAuthentication(String domain, String username, byte[] challenge, 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.
public boolean equals(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.
public byte[] getAnsiHash(byte[] challenge)
Computes the 24 byte ANSI password hash given the 8 byte server challenge.
public String getDomain()
Returns the domain.
public static byte[] getLMv2Response(String domain, String user, 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).
public String getName()
Return the domain and username in the format:
domain\\username. This is equivalent to toString().
public static byte[] getNTLMResponse(String password, byte[] challenge)
Generate the Unicode MD4 hash for the password associated with these credentials.
public 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.
public static byte[] getPreNTLMResponse(String password, byte[] challenge)
Generate the ANSI DES hash for the password associated with these credentials.
public byte[] getUnicodeHash(byte[] challenge)
Computes the 24 byte Unicode password hash given the 8 byte server challenge.
public String getUsername()
Returns the username.
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.
public int hashCode()
Return the upcased username hash code.
public String toString()
Return the domain and username in the format:
domain\\username. This is equivalent to getName().
