Kontalk Messenger
A fully open source short message service featuring encrypted communication.
What is Kontalk Messenger?
Kontalk is a secure instant messenger, allowing you to send and receive text, image and voice messages (other file types coming soon) to and from other Kontalk users completely free of charge.
Kontalk Features:
- Your phone number is your ID. No usernames or passwords.
- It automatically finds other Kontalk users by looking at your address book, making it even easier to start chatting on Kontalk with your friends.
- End-to-end encryption ensures safe and private conversations, so that only you and the person you are talking to can read them.
- Both client-to-server and server-to-server channels are fully encrypted. Users can be safe with end-to-end encryption — servers can't decrypt it.
- Your and all phone numbers used on the network are irreversibly encrypted.
- It supports multiple devices, making it very easy to start chatting on your phone and continue the conversation on your tablet.
- Based on open standards: XMPP and OpenPGP.
