Method Detail

getMethod

public java.lang.String getMethod()

Description copied from interface: AuthenticationMechanism

Return the SSH method name for this authentication. e.g "password"

Specified by:

getMethod in interface AuthenticationMechanism

Returns:

String

init

public void init(TransportProtocol transport,
                 AuthenticationProtocol authentication,
                 byte[] sessionId)
          throws java.io.IOException

Description copied from interface: AuthenticationMechanism

Initializes the mechanism with variables.

Specified by:

init in interface AuthenticationMechanism

Parameters:

transport - the transport protocol

authentication - the authentication protocol

sessionId - the id of the current session.

Throws:

java.io.IOException

createDefaultConfiguration

protected javax.security.auth.login.Configuration createDefaultConfiguration(SshContext context)

Create the default JAAS Configuration. Sub-classes may override instead of using the configuration supplied by SshContext.

Parameters:

context - context

Returns:

JAAS configuration

getServicePrinicipal

protected java.lang.String getServicePrinicipal(SshContext context)

startRequest

public boolean startRequest(java.lang.String username,
                            byte[] msg)
                     throws java.io.IOException

Description copied from interface: AuthenticationMechanism

Start an authentication transaction. If the authentication mechanism is simple and you can determine the result from all information received in the SSH_MSG_USERAUTH_REQUEST message, you should call the approriate completion methods on the AuthenticationProtocol instance that was passed in the initialization process. The request data varies according to the authentication method.

 if (success)
   authentication.completedAuthentication(method, username, service);
 else
   authentication.failedAuthentication(method);
 

Specified by:

startRequest in interface AuthenticationMechanism

msg - the request data from the SSH_MSG_USERAUTH_REQUEST message

Returns:

true if the message was processed, otherwise false

Throws:

java.io.IOException

processMessage

public boolean processMessage(byte[] msg)
                       throws java.io.IOException

Description copied from interface: AuthenticationMechanism

If the SSH protocol authentication method defines additional messages which are sent from the client, they will be passed into your implementation here when received.

Specified by:

processMessage in interface AuthenticationMechanism

Returns:

boolean

Throws:

java.io.IOException
