Cyptalk is a HTML5/Node.js based encrypted instant chat

Features

• Client side AES-256-CBC encryption/decryption (the server is just a messenger)
• 256 bit key derived from your passphrase using PBKDF2
• Optional nicknames
• Random (UUID v4) channel name generation för less guessability
• Quick-links (not recommended) using http://server/#Room:Passphrase
• Super simple setup
• Notification sounds (mutable)
• Flashing title on new messages
