The client's IP address.

isConnected

public boolean isConnected()

Returns:

if client still connected

public abstract int encrypt(byte[] data,
                            int offset,
                            int size)

Encrypt the data in-place.

Parameters:

data - - the data to be encrypted

offset - - the initial index to be encrypted

size - - the length of data to be encrypted

Returns:

The data size after encrypted

decrypt

public abstract boolean decrypt(byte[] data,
                                int offset,
                                int size)
