The problem with private key encryption is that the private key must somehow be transmitted to the other party without it being intercepted and used to decrypt the information. In addition, each unique two parties would need a unique key to protect the data. The resulting key management is the main obstacle to implementing private key encryption, which is a must-have technology.
Public key, or asymmetric, encryption uses a combination ...
