Encryption is a way to protect all sorts of data through different kinds of networks. It allows us to share private data including our financial details, medical records and personal information online in a secure way, knowing that it cant be intercepted or seen by other people. It means people can communicate with another person, safe in the knowledge no-one is listening in. But some policymakers and law enforcement are putting all this at risk by creating ways to break into your encrypted data. Why? Because they think this is the best solution to catching criminals who use encryption too. The problem is you can't just allow certain people to break encryption. If law enforcement can break in to your stuff, so can criminals. The threat to encryption is massive, but on Global Encryption Day, together, can we defend it!
