What is public key encryption?
Rating:
Public key encryption is one of the encryption types, which uses a public key that is known to everyone and a private key that is known only to the recipient of the message. When a user wants to send a secure message to another user, the sending user uses the target user's public key to encrypt the message, and the target user then decrypts the message using his private key, which is known only to the target user. If a public key is used to encrypt a message, only the corresponding private key can be used to decrypt it.
