public TwoQuestionsPlugin()

Method Detail

destroy

public void destroy()

Description copied from interface: AuthenticationPlugin

Called by the driver when this extension should release any resources it is holding and cleanup internally before the connection is closed.

Specified by:

destroy in interface AuthenticationPlugin<NativePacketPayload>

getProtocolPluginName

public java.lang.String getProtocolPluginName()

Description copied from interface: AuthenticationPlugin

Returns the client-side name that the MySQL server uses on the wire for this plugin.

Specified by:

getProtocolPluginName in interface AuthenticationPlugin<NativePacketPayload>

Returns:

plugin name

requiresConfidentiality

public boolean requiresConfidentiality()

Description copied from interface: AuthenticationPlugin

Does this plugin require the connection itself to be confidential (i.e. tls/ssl)...Highly recommended to return "true" for plugins that return the credentials in the clear.

Specified by:

requiresConfidentiality in interface AuthenticationPlugin<NativePacketPayload>

Returns:

true if secure connection is required

isReusable

public boolean isReusable()

Specified by:

isReusable in interface AuthenticationPlugin<NativePacketPayload>

Returns:

true if plugin instance may be reused, false otherwise

setAuthenticationParameters

public void setAuthenticationParameters(java.lang.String user,
                                        java.lang.String password)

Description copied from interface: AuthenticationPlugin

This method called from Connector/J before first nextAuthenticationStep call. Values of user and password parameters are passed from those in NativeAuthenticationProvider#changeUser() or NativeAuthenticationProvider#connect(). Plugin should use these values instead of values from connection properties because parent method may be a changeUser call which saves user and password into connection only after successful handshake.

Specified by:

setAuthenticationParameters in interface AuthenticationPlugin<NativePacketPayload>

Parameters:

user - user name

password - user password

nextAuthenticationStep

public boolean nextAuthenticationStep(NativePacketPayload fromServer,
                                      java.util.List<NativePacketPayload> toServer)

Description copied from interface: AuthenticationPlugin

Process authentication handshake data from server and optionally produce data to be sent back to the server. The driver will keep calling this method on each new server packet arrival until either an Exception is thrown (authentication failure, please use appropriate SQLStates) or the number of exchange iterations exceeded max limit or an OK packet is sent by server indicating that the connection has been approved. If, on return from this method, toServer is a non-empty list of buffers, then these buffers will be sent to the server in the same order and without any reads in between them. If toServer is an empty list, no data will be sent to server, driver immediately reads the next packet from server. In case of errors the method should throw Exception.

Specified by:

nextAuthenticationStep in interface AuthenticationPlugin<NativePacketPayload>

Parameters:

fromServer - a buffer containing handshake data payload from server (can be empty).

toServer - list of buffers with data to be sent to the server (the list can be empty, but buffers in the list should contain data).

Returns:

return value is ignored.

reset

public void reset()

Description copied from interface: AuthenticationPlugin

Resets the authentication steps sequence.

Specified by:

reset in interface AuthenticationPlugin<NativePacketPayload>
