     [java] Now you can login using an SSH client, with:
     [java]  User Name: sjsh
     [java]  Private Key: D:\workspace\SecureJSH\SJSH-Demo-Root\home\sjsh\.ssh\id_rsa
     [java]
     [java] Type in anything to stop:

Using username "sjsh".
Authenticating with public key "imported-openssh-key"

This is an interactive Java(TM) shell, type in Java(TM)
statements to get them executed.

Type in Ctrl^D to logout.

Type in ? or help for a list of available commands.

Type in <Tab> to complete commands.

Use UP/DOWN arrow keys for command history.

Here you are in the demo shell.

There are two demo built-in commands: 'msg' and 'msgs',
and one built-in field: 'msgs', those are added by this demo.

Try them out and write your own shell similarly.

Built-in commands:

class <class-name> +<class-code>
   Start defining a new class in current package
def <field-name> [ <type> [<comment> | -] | - ]
   Define a field that persists across statements
feedback [ on | off ]
   Control display of feedbacks
fields
   Show all fields currently defined
import <package-name>.* | static <qualified-class-name>.*
   Add an import
imports
   Show all imports in current import list
lineNo [ on | off ]
   Control display of line numbers
msg <message> | +<multi-line message>
   Leave a message
msgs
   Show all messages in demo shell 'msgs' list
package [ <package-name> ]
   Specify current package
preview [ on | off ]
   Control display of previews
redef <field-name> [ <type> [<comment> | -] | - ]
   Redefine a field that persists across statements
undef <field-name>
   Undefine an existing field
unimport <existing-import> | *
   Remove specified import

Type in:   help | ? <cmd-name> [<topic>]
for more details of a built-in command.

The following built-in methods:
  void javap(Class<?> c); void javap(Class<?> c,int depth);
  void javap(Object o); void javap(Object o,int depth);
can be used to examine the structure of any Java class (of an
Java object), where <depth> specifies how many classes up the
inheritance hierarchy should be printed, 0 for infinite.

Type in:   javap(this);
to see all built-in methods and fields listed.

博主你好。关于这个项目不知道你熟悉吗，有些问题想请教你。我现在运行起这个项目的demo，但是使用SecureCrt无法指定公钥文件链接到server程序，希望博主能指点一二。另外如果我希望把认证方式改为传统的user/password方式，不知道这个项目是否实现了这种认证方式。

    public PasswordAuthResult authenticateUser(String userName,
        char[] password, char[] newPassword)
    {
        // TODO implement password authentication, consider JAAS for it
        return PasswordAuthResult.FAILURE;
    }
