After WhatsApp, Facebook Messenger and Google Allo, Skype also jumped in the field of encrypted and safe chat. The software for VoIP calls and video calls owned by Microsoft is the latest instant messaging platform to integrate within their source code the protocol encryption end to end Signal.
Made by the homonymous software house – and used by the homonymous instant messaging app – Signal is recognized by many as the best cryptographic protocol for the chat. With this addition, Skype joins the large group chat that allows their users to send private messages and safe (like Google incognito Allo, the secret conversations of Messenger and all conversations on WhatsApp and Signal). At the moment, end-to-end encryption will be applied only to text chats (text messages, images, videos), while VoIP calls and video calls are still “unencrypted”.
With end-to-end encryption, Microsoft developers have been able to add the “Private Conversation” feature to the many already present in Skype. To create a private chat, click on the “+” button at the top of the user interface and choose “Private conversation” from the options available. At this point, you can choose the contact to send an invitation to join the secret chat.
The chosen contact has seven days to accept and start to send with you in a secure and encrypted way: in case the invitation expires, you will have to send another one for a new encrypted chat. If, on the other hand, the invitation should be accepted, the private conversation will appear in the list along with the other active chats: just click on it to read the messages sent or send new ones.
To delete a secret chat Skype, all you have to do is select it from the list of active chats, click on it with the right mouse button and select ” Delete conversation ” in the context menu that appears. To retrieve the deleted messages Skype just sends a new invitation and wait for our contact to accept it: the entire message history will be retrieved from the servers, decrypted and made accessible again to the two contacts.
