Question

Quizplus · Accepted Answer

Public key encryption ciphers are generally not used to encrypt very long messages directly due to their slow processing speed. Instead, they are often used to encrypt a small piece of data, such as a key for a symmetric cipher, which is then used to encrypt the actual message. This approach combines the security of public key encryption with the efficiency of symmetric encryption.
