What popular encryption algorithm requires that both the sender and receiver know a pre-shared key?

  • PKI
  • MD5
  • HMAC
  • AES
    Answers Explanation & Hints:

    MD5 is a hashing algorithm that guarantees that no one intercepted the message and altered it. Advanced Encryption Standard (AES) is a popular symmetric encryption algorithm where each communicating party needs to know the pre-shared key. Public key infrastructure (PKI) is an asymmetric encryption algorithm based on the assumption that the two communicating parties have not previously shared a secret key. HMAC is a hash message authentication code that guarantees that the message is not a forgery and actually comes from the authentic source.
