What is Encryption?

Scrambling data into an unreadable code, so that only someone with the right key can turn it back, is called encryption. It protects data by making it worthless to anyone who intercepts or steals it without the key.

Encryption is like sending a secret letter. You scramble the message into a code before mailing it. Anyone who opens the envelope along the way sees only gibberish. Only the friend who holds the right key can turn the code back into words.

How Encryption Works

Readable data is called plaintext
