# Encryption

Concept · [Cloud, hosting and security](https://ecosystem.samcarlton.com/cloud)

Also called: encrypted, encrypt, encryption at rest, encryption in transit, encrypted at rest

Scrambling data with a key so only someone with the right key can read it. Encryption in transit protects data moving across a network. Encryption at rest protects data stored on a [disk](https://ecosystem.samcarlton.com/filesystem).

**For example:** A thief steals a laptop that holds an encrypted customer list. Without the key, the thief sees only scrambled data.
