ion which handles BoringSSL TLS RSA operations using Intel AVX-512 multi-buffer acceleration. When a new handshake happens, BoringSSL invokes the private key provider to request the cryptographic operation, and then the control returns to Envoy. The RSA requests are gathered in a buffer. When the buffer is full or the timer expires, the private key provider invokes Intel AVX-512 processing of the buffer. When processing is done, Envoy is notified that the cryptographic operation is done and that it may cont
