> kontalk is a Free Software replacement for whatsapp - you can chat
> with anyone if you know their phone number using a data connection
> (cheaper sms for many people). See http://kontalk.org

> Currently it is available only on android. Their next version would
> support XMPP and it would make it easy to get it working on other
> platforms.

> One person in the audience at Mumbai asked me how they would know if
> my contact has a kontalk account if they don't store everyone's
> number? I asked the upstream and he confirmed my guess.

> When you register your number, the server sends you an sms to confirm
> your number and the number is discarded. A one way hash of the number
> is used as username (like storing passwords, the server can never
> guess the number based on the hash). So when you want to talk to
> someone in your phone contact list, the client will make a hash and
> send it to the server to find the public. The public key of the user
> will be signed by the server and all communications will be end to end
> encrypted. Only way to spy would installing apps on the users' phones.

> This is simply brilliant, the encryption solution we have been waiting

> This is a real, easy, working, free software solution for completely

> harder to catch terrorists now, but you gave us no choice when you
> misused your powers. You were not looking for terrorist when you were
> listening to Angela Merckel, Dilma Rouseff, UN or EU parliament, it is
> only about power and control.

> Please share this widely in your local lists and networks.
