If you are looking for a securely encrypted chat method, consider using the website CryptoCat...
If the country you live in is possibly spying on you (ok, any country these days) and you need encrypted chat that also allows for multiple person party chat, this could be for you. This could save lives be it sharing off the record news, planning an uprising, a revolution, or just talking about who the world elite will pick for the next president of the United States come November. You can never be too safe these days.
The teen author who developed CryptoCat, Nadim Kobeissi, has been routinely detained and interrogated at U.S. border crossings and questioned about the encryption algorithms.
