Certified Ethical Hacker (CEH) Practice Question

While reviewing an HTTPS capture, you notice the negotiated cipher suite is TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256. From the standpoint of bulk data encryption in the TLS session, which part of the suite actually carries out the confidentiality function and what is its effective key size?

  • ECDHE performs the content encryption by deriving a 256-bit key.

  • AES in GCM mode with a 128-bit key provides the session's confidentiality.

  • RSA with a 2048-bit (or larger) modulus encrypts the bulk data.

  • SHA-256 is the algorithm that encrypts the application records.
