More and more messengers and chat apps to encrypt their communication. No one wants that other parties can see what is written or said. The one chat app is a bit better protected than the other, and an app as the Signal crosses some privacy concerns still top out. But Cyphr is also a throw back to the app where privacy is of paramount importance. Cyphr enables the sending of encrypted messages a lot easier.

Only the most necessary metadata is stored, so that your message reaches the receiver.

Then generate the app, a special key for you, both a public and a private key that will be used to get your messages to encrypt. It is, therefore, a unique key that only works for you. You can then have a conversation with someone start. Invite someone through your contact list, where the app access to have to give or e-mail.

The way of communicating works more or less the same as other apps. You can easily have a conversation with a person or start a conference call.

You can do this easily in the settings. That way you will have control over what happens.
