UNDERSTAND THE IDEA

Public and private keys

THE CONCEPT

Asymmetric encryption helps solve key distribution. A public key can encrypt for its owner; only the matching private key decrypts. A key pair does not itself prove whose key it is.

YOUR MISSION

Generate keys, encrypt a made-up message, then decrypt it. The private key never leaves this browser session.
