What is encryption?

Explanation:
Encryption is the process of turning readable data into a scrambled form so that only someone with the right key can read it again. It’s about keeping information confidential, so even if someone intercepts or steals the data, they can’t understand it without the key. This is why describing encryption as scrambling data to stop third parties from accessing it fits best. Other options refer to different goals: compression reduces size, checksums verify that data hasn’t been tampered with, and deduplication cuts duplicate data to save space. Those techniques don’t inherently protect the content from being read like encryption does.
