Class MasterPasswordClient

java.lang.Object
  ariba.util.core.MasterPasswordClient

public final class MasterPasswordClient
extends java.lang.Object

Manages master password. For security reasons, it may be required to pass in the master password via std in. Whether this is the case is specified by 1 of the 2 command line options: -readMasterPassword and -masterPasswordNoPrompt. When a commmand line tool is invoked, ArgumentParser will invoke methods from this class to read the master password from the stdin. Whether the user is prompted or not depends on which of the above options are present. If -masterPasswordNoPrompt is present, then the user will not be prompted (in such cases the 'user' is most likely some parent process executing the command line). Otherwise, if -readMasterPassword is present, then the user will be prompted. The master password is then stored and made available for the process via the call getMasterPassword().

Method Detail

getMasterPasswordClient

public static MasterPasswordClient getMasterPasswordClient()

Get the master password client. Note that this is a singleton. Also this method is not synchronized. If multiple threads call this method, the last one wins, and previously instantiated instances of this class are simply garbage collected.

getMasterPassword

public java.lang.String getMasterPassword()

Returns the master password. Should be called after processArguments. It is incorrect to call this method before prcoessArguments is called, in which case null will be returned.

the master password, null if no masterPassword options are specified in the command line when processArguments(ariba.util.core.CommandLine, ariba.util.core.ArgumentParser) is called.
