#### Answer Description

Public/Private key encryption is asymmetric, meaning anything encrypted with one key must be decrypted using the opposite key. If the data was encrypted with the public key, only the private key can decrypt it.

#### Wikipedia

Public-key cryptography, or asymmetric cryptography, is a cryptographic system that uses pairs of keys Each pair consists of a public key (which may be known to others) and a private key (which may not be known by anyone except the owner) The generation of such key pairs depends on cryptographic algorithms which are based on mathematical problems termed one-way functions Effective security requires keeping the private key private the public key can be openly distributed without compromising securityIn such a system, any person can encrypt a message using the intended receiver's public key, but that encrypted message can only be decrypted with the receiver's private key
