This document is an attempt to pin down all the things you don't think about when quoting for a project, and hopefully provide a starting point for some kind of framework to make quoting, working and delivering small-medium jobs more predictable and less stressful.

The hardest bit of any job, and lots of pitfalls

This guide will demonstrate the steps required to encrypt and decrypt files using OpenSSL on Mac OS X. The working assumption is that by demonstrating how to encrypt a file with your own public key, you'll also be able to encrypt a file you plan to send to somebody else using their private key, though you may wish to use this approach to keep archived data safe from prying eyes.

Assuming you've already done the setup described later in this document, that id_rsa.pub.pcks8 is the public key you want to use, that id_rsa is the private key the recipient will use, and secret.txt is the data you want to transmit…

$ openssl rand 192 -out key

$ openssl aes-256-cbc -in secret.txt -out secret.txt.enc -pass file:key
