Microsoft has teamed up with Encrypted Messaging App Signal to bring an end-to-end encryption feature to Skype.
The new Skype feature, dubbed Private Conversations, will be powered by Signal Protocol. The Skype Private Conversations will enable users to have more secure conversations, with strong encryption properties.
Skype will have a New Private Conversation option, using which an invitation for private chat can be sent to the selected contact. This invitation should be accepted within a week or it will expire.
The users can have private conversation only from the device with which the conversation was initiated. For example, if you have initiated conversation from your cell phone, you can’t continue it from laptop (unless you send a new invitation).
Additionally, users can’t edit the messages or forward files from private conversations to any other user. Private Conversations can only take place between two people; not in groups.
Skype will feature End Conversation and Delete Conversation options for private conversations. The deleted and ended conversations can’t be continued without sending a new invitation.
