Encryption & Security

What Is Public Key Encryption?

Encryption using a key pair - a public key for encrypting, a private key for decrypting.

In asymmetric encryption, each user has a key pair: a public key, which can be shared freely, and a private key, kept secret. Data encrypted with the public key can only be decrypted with the matching private key - the foundation of protocols like TLS.
