To transmit data over TLS, firstly TLS handshake should be finished and then the application data will be transferred over TLS. Which phase does QAT engage in: only TLS handshake, or both TLS handshake and application data transferring over TLS?
Intel® QAT engage in both phases: TLS handshake and data transferring over TLS. Basically, what Intel® QAT does is offloading the computation of cryptographic related operations that may happen during the TLS handshake or during data transferring over TLS.
