SSL

1. 1-way SSL (a.k.a. Server Authentication)
   1. Client confirms the server’s identity via the server’s provided certificate by verifying it with a CA (Certificate Authority).
   2. Then the Public Key contained in the received certificate is used along the Session Key to encrypt all sent/received messages.
2. 2-way SSL (a.k.a. Client Authentication, Mutual Authentication)
   1. Server and Client confirm the other’s identity after each share their own public certificate by verifying it with a CA.
   2. Then the Public Key contained in the received certificate is used along the Session Key to encrypt all sent messages.

Install dnsmasq

Via brew or other method

Set up DNS resolver order

In order to work on every connection and on any TLD, dnsmasq needs to be the first DNS resolver receving the query.

And since dnsmasq is a local process, all DNS queries need to go to 127.0.0.1

On macOS, /etc/resolv.conf is automaticaly created, depending on a variety of things (network settings, etc), so it cannot be edited.
