The repository for the assignment is public and Github does not allow the creation of private forks for public repositories.
The correct way of creating a private frok by duplicating the repo is documented here.
For this assignment the commands are:
git clone --bare [email protected]:usi-systems/easytrace.git

const ENCRYPTION_KEY: string = process.env.ENCRYPTION_KEY || ""; // Must be 256 bits (32 characters) | |
const IV_LENGTH: number = 16; // For AES, this is always 16 | |
/** | |
* Will generate valid encryption keys for use | |
* Not used in the code below, but generate one and store it in ENV for your own purposes | |

export function keyGen() { |
This service assumes that you followed the SSR receipt at ng-cli (i.e. you use the '@nguniversal/express-engine' package).
This is a quick guide for setting up a kill switch using UFW (Uncomplicated FireWall). It is assumed you are using OpenVPN and optionally Network-Manager with network-manager-openvpn.
Before we can start we're going to need the IP address (or the IP addresses) of your VPN so that we can whitelist those later on, write them down. They are obviously going to be different for every VPN and VPNs with multiple servers, so I'll leave this up to you.
On some systems UFW is installed and enabled by default (Ubuntu, for example). Installation procedure is going to be different for every distribution of GNU/Linux, but it's usually something like
