Using the terminal we are going to connect to cyberstorm.mu which is acting as the server here, using OpenSSL from our VM which is the client. The command to be used : openssl s_client cyberstorm.mu:443 Note: s_client means we are in client mode and 443 is the port through which we are connecting to cyberstorm.mu Result from the command But what we are most interested in all of the output given is the ' Server Temp Key ' field. This field will help us identify whether this connection is using a post-quantum secure connection. As we are only focusing on the ' Server Temp Key ' field, we are going to use ' grep ' command with a pipe so we can search that field from the given output. The command to be used :  openssl s_client cyberstorm.mu:443 | grep 'Server Temp Key' Result from above command How to know if a connection is using a post-quant...
