Facebook Messenger: secret conversations encryption and end-to-end inbound


To date, the most effective technology to protect online conversations from prying eyes is the end-to-end encryption. The company Zuckerberg explains it this way: "It means that the messages are intended only for you and the other person and no one else, including us. In a secret conversation, You can also set a timer to control the time during which each message is displayed in the conversation. "

Facebook's technology uses the Signal Protocol Open Whisper Systems, the same on which the cryptographic protection system used by WhatsApp, application - remember him - still belongs to Facebook. Unlike the approach used on WhatsApp, not all conversations made using your Facebook Messenger will be protected by encryption, end-to-end. Start a secret conversation with someone will optional, will be the user to set it as "secret."

The reason is simple: unlike WhatsApp, which is used only on a single device, Messenger can be used on smartphones, tablets, and personal computers. The secret conversations can only be read on one device and it is for this that the approach on the two applications is so different. In secret conversations is also not expected (at least temporarily) support for advanced content such as GIF or video, it is not possible to make payments or use other typical features of the service.


At the time of writing the secret conversations are available on a limited test basis, but a complete roll-out will be started later this summer. During the test, the company will collect feedback on the functionality from users, by measuring performance and introducing tools to help flag content.

Hello and welcome back to Max Q! Last week wasn’t the most successful for spaceflight missions. We’ll get into that a bit more below. In this issue: First up, a botched launch from Virgin Orbit… …followed by one from ABL Space Systems News from Rocket Lab, World View and more Virgin Orbit’s botched launch highlights shaky financial future After Virgin Orbit’s launch failure last Monday, during which the mission experienced an  “anomaly” that prevented the rocket from reaching orbit, I went back over the company’s financials — and things aren’t looking good. For Virgin Orbit, this year has likely been completely turned on its head. The company was aiming for three launches this year, but everything will remain grounded until the cause of the anomaly has been identified and resolved. It’s unclear how long that will take, but likely at least three months. Add this delay to Virgin’s dwindling cash reserves and you have a foundation that’s suddenly much shakier than before. ...
