The "Signalgate" scandal has raised the issue of encryption to a broader audience in the past week. On the plus side, many sources say that 95% of digital traffic is encrypted now, compared to 43% in 2014, but most people have no idea that their personal data is being encrypted. It’s one of those invisible technologies that touch many people.

But there is a basic fact, that a lot of stuff that should be secured, isn’t because users don’t know they have to turn it on For example, WhatsApp, the messenger platform from Meta, advertises that they have end to end encryption, but they don’t tell you that you have to turn it on to get that benefit.

And not just encryption but fully homomorphic encryption, an important step forward in protecting our data
