Last January skype announced end-to-end encrypted Private Conversations and now it becomes live for users on Android, iOS, Mac, Linux and Windows desktop platforms. During the skype private conversation all the calls, messages and image/audio/video are encrypted. At this time the users can make only one private conversation from a single device at a time and the messages will strike at the same device, but you can switch the conversations. The invitation is valid only for 7 days.”]
