What is Encryption?
Scrambling information so only someone with the right key can read it. It protects data on your devices and as it travels online.
Encryption is everywhere: the padlock (HTTPS) in your browser encrypts data between you and a website; your phone encrypts its storage once a screen lock is set; encrypted messaging apps protect conversations. It is the digital equivalent of closing the curtains — normal, not suspicious — and it protects ordinary things: bank details, medical news, private conversations.
