Package jcifs.smb
Class NtlmPasswordAuthentication
java.lang.Object
jcifs.smb.NtlmPasswordAuthentication
- All Implemented Interfaces:
Serializable
,Principal
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.

NtlmPasswordAuthentication
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
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(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.

Method Details
-
getPreNTLMResponse
Generate the ANSI DES hash for the password associated with these credentials. -
getNTLMResponse
Generate the Unicode MD4 hash for the password associated with these credentials. -
getLMv2Response
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).
-
getNTLM2Response
public static byte[] getNTLM2Response(byte[] nTOWFv1, byte[] serverChallenge, byte[] clientChallenge) -
nTOWFv1
-
nTOWFv2
-
getLMv2Response
public static byte[] getLMv2Response(byte[] responseKeyLM, byte[] serverChallenge, byte[] clientChallenge) -
getNTLMv2Response
public static byte[] getNTLMv2Response(byte[] responseKeyNT, byte[] serverChallenge, byte[] clientChallenge, long nanos1601, byte[] targetInfo) -
getDomain
Returns the domain. -
getUsername
Returns the username. -
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
Return the domain and username in the format: domain\\username. This is equivalent to toString(). -
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
- 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
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. -
hashCode
public int hashCode()Return the upcased username hash code. -
toString
Return the domain and username in the format: domain\\username. This is equivalent to getName().
