In a hybrid cryptographic system, usually:
A.
Digital certificates cannot be used.
B.
Neither public key nor private key cryptography is used.
C.
Public key cryptography is used for the encryption of the message.
D.
Private key cryptography is used for the encryption of the message.
Someone mind explaining the answer? Its not very clear to me. I thought Public Key Encryption is used for the initial encrypt/decrypt, and then the shared key (private key encryption) is then used for the final decryption?

“Hybrid encryption is achieved through data transfer using unique session keys along with symmetrical encryption. Public key encryption is implemented for random symmetric key encryption. The recipient then uses the public key encryption method to decrypt the symmetric key. Once the symmetric key is recovered, it is then used to decrypt the message.”
