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 engages in both TLS handshake and data transferring phases. It offloads the computation of cryptographic operations during these phases.
