Generate private key (.key)

# Key considerations for algorithm "RSA" ≥ 2048-bit
openssl genrsa -out server.key 2048

# Key considerations for algorithm "ECDSA" ≥ secp384r1
# List ECDSA the supported curves (openssl ecparam -list_curves)

Secure sessions are easy, but not very well documented.  
Here's a recipe for secure sessions in Node.js when NginX is used as an SSL proxy:

The desired configuration for using NginX as an SSL proxy is to offload SSL processing 
and to put a hardened web server in front of your Node.js application, like:

[NODE.JS APP] <- HTTP -> [NginX] <- HTTPS -> [PUBLIC INTERNET] <-> [CLIENT]

Edit for express 4.X and >:  Express no longer uses Connect as its middleware framework, it implements its own now.

Postgres Cheatsheet

This is a collection of the most common commands I run while administering Postgres databases. The variables shown between the open and closed tags, "<" and ">", should be replaced with a name you choose. Postgres has multiple shortcut functions, starting with a forward slash, "". Any SQL command that is not a shortcut, must end with a semicolon, ";". You can use the keyboard UP and DOWN keys to scroll the history of previous commands you've run.
