C# Class SharpCifs.Smb.NtlmPasswordAuthentication

This class stores and encrypts NTLM user credentials.

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.

Method	Description
Equals ( object obj ) : bool	Compares two `NtlmPasswordAuthentication` objects for equality. 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.

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.
