System of encrypting electronic files using a key pair. The key pair contains a public key used during encryption, and a corresponding private key used during decryption.
An encoding scheme that uses a public key to encrypt data, which can be decrypted with the corresponding private or secret key (or, alternatively, one that encrypts using a secret key and decrypts with a public key).
public key encryption - A method of encryption that uses a pair of mathematically related keys: a public key and a corresponding private key. Either key can be used to encrypt data, but the corresponding key must be used to decrypt it. Also called asymmetric encryption.
