Definition
Public-key cryptography uses a key pair: a public key anyone can use to encrypt or verify, and a private key only the owner should use to decrypt or sign.
Real-World Example
HTTPS certificates rely on public-key cryptography so your browser can verify a site’s identity and negotiate secure keys.
