Encrypted reverse connections using OpenSSL

To encrypt our communication, we will use SSL here. To do that, we first need to generate an SSL certificate. We can generate a custom SSL certificate using the following command:

openssl req -x509 -newkey rsa:4096 -keyout key.pem -out cert.pem -days 365 -nodes req -x509 → requests from openssl to generate X.509 certificate 
-newkey rsa:4096 → generate new keys with size 4096 using RSA 
-keyout key.pem → saves the keys in key.pem file 
-out cert.pem → saves the certificate in cert.pem file 
-days 365 → certificate valid for 365 days 

The nodes command is not nodes; it's no DES. This refers to the fact ...
