[openssl-users] Openssl async support

Hi all,

I have some queries regarding OpenSSL async operation.

Current setup
I have one* OpenSSL dynamic engine (with RSA and AES-GCM support) *and
linked it with *Nginx* server. Multiple *WGET* commands on the client side.

Current issue
  Since OpenSSL *do_cipher call *(the function in which actual AES-GCM
encryption/decryption happening) comes from one client at a time which is
reducing file downloading performance. So we need an *asynchronous
operation in OpenSSL* ie. we need multiple do_cipher calls at the same time
from which we should submit requests to HW without affecting the incoming
requests and should wait for HW output.

 1) Is there is any other scheme for multiple do_cipher calls at a time?.
 2) Any method to enable asynchronous call from OpenSSL?

Openssl - 1.1.0h
Wget 1.17.1

 Kindly support me. Please inform me if any more inputs needed. Thanks in
