PSQL

Magic words:

psql -U postgres

Some interesting flags (to see all, use -h or --help depending on your psql version):

-E: will describe the underlaying queries of the \ commands (cool for learning!)
-l: psql will list all databases and then exit (useful if the user you connect with doesn't has a default database, like at AWS RDS)

1. Overview

This is an example of using module tls in NodeJS to create a client securely connecting to a TLS server.

It is a modified version from documentation about TLS, in which:

The server is a simple echo one. Clients connect to it, get the same thing back if they send anything to the server.
The server is a TLS-based server.
Clients somehow get the server's public key and use it to work securely with the server
