Encryption
Simple Explanation
A way of scrambling information so people without the correct key cannot easily read it. It helps protect messages, payments and stored files. Encryption does not guarantee that every website or message is trustworthy.
Technical Explanation
Encryption transforms plaintext into ciphertext using a cryptographic algorithm and key. Authorized parties decrypt it with the appropriate key; implementations vary by use case.
Business Use Case
A healthcare provider encrypts stored patient files to reduce exposure if storage is accessed without authorization.
Real-Life Example
When you visit a secure HTTPS website, encryption helps protect information traveling between your browser and the site.
