The description of Twino

Simple instant messenger based on XMPP (Jabber) protocol with enhanced security.
Please note, software is under active development.

- Strong end-to-end encryption.
- Encrypted P2P (if available) voice calls (in Twino+ available for Android 4.0+)

- If you forget your password - there's NO way to restore it or encryption keys.
- If you disable backup & sync - you'll greatly improve safety, but you'll be unable to chat with your contacts using another device, since your keys will be out of sync.
- If you want guaranteed security during conversations - add contacts with "Generate Verification Key" option, and deliver it to your party using trusted channel.

How it works (in brief):
- Each contact in your list uses unique pair of RSA and AES encryption keys.
- Each message is encrypted with unique key.
- Each voice call is encrypted with unique key.
- Your password is improved with unique random key stored in your phone.
- If you use Verification Key for contact, there's no known way to send or read your messages for anyone except you and your party.

- Interface improvements including tablet version.
- More languages.
- Windows/Linux version
