…honGH-97613) Fix a shell code injection vulnerability in the get-remote-certificate.py example script. The script no longer uses a shell to run "openssl" commands. Issue reported and initial fix by Caleb Shortt. Remove the Windows code path to send "quit" on stdin to the "openssl s_client" command: use DEVNULL on all platforms instead.
