CISA · Question #644
Which of the following BEST describes the process of creating a digital envelope?
The correct answer is C. A message is encoded using symmetric encryption, and then the encryption key is secured using. A digital envelope is created by encrypting the message using symmetric encryption for efficiency, then securing the symmetric encryption key by encrypting it with the recipient’s public key so it can be safely transmitted and only decrypted by the intended recipient.
