Encryption
Turning readable data into scrambled data that can only be read with the right key
What's it for?
Makes information unreadable to people who are not supposed to see it.
For example…
A laptop disk is encrypted so a stolen machine does not expose readable customer files without the key
A stolen laptop contains encrypted files, so someone without the key cannot simply remove the drive and read the customer data
Think of it like…
Putting a message in a locked box: anyone may see the box, but only someone with the right key can open it
