Node RC4 chat

A wrapper for socket that implement a p2p connection with possibility of adding a cryptographic Layer

This class does not allow multiple clients

Internal Fields:

• server = socket listener
• port = port where the server listen to
• cipher = transform stream to cipher messages
• decipher = transform stream to decipher incoming messages
• endPoint = point where the clear messages can be read (it can be the socket itself, if no cryptographic layer was set)
• startPoint = point where the clear messages can be written (it can be the socket itself, if no cryptographic layer was set)
• socket = connection to another instance of this chat

Public Read Only Attribute

• connected = true if a connection was established

Public Write Only Attribute

• key = when a key is set, new cipher and decipher are created and piped in socket, so new messages are encrypted before they are sent, and decrypted when they come.

Public Methods

• write(data, enc) = write data into startPoint
• connect(options) = connect this chat to a remote instance.
• disconnect() = disconnect the chat if a connection is established
• setCryptoLayer(cipher, decipher) = wrap chat with a cryptographic layer. cipher and decipher are Transform streams

Triggered Events

• connect = triggered when a client was connected
• busy = triggered when a connection is about to be established with a chat in progress
• close = triggered when a connection is closed
• data = triggered when a message arrives
