Use Multiple CPU Cores with Worker

A Worker provides a way for you to have code that runs on multiple CPU cores. A Worker achieves this by running its code in a Console app. One or more of these console apps are started based on your Worker settings. Since these run as Console apps, the OS treats them as separate processes and spreads them out amongst available CPU cores.

Code Tip: How to Implement the ARC4 Encryption Algorithm

ARC4 is a symmetric encryption algorithm fast and easy to implement. Being symmetric does means that it uses the same function with the same key (varying from 40 to 2048 bits) both for cyphering and de-cyphering a block of data.

Is it the most secure or robust encryption algorithm around? Not really. But it provides a good amount of performance and you can take further steps in order to correct some of its flaws. So, continue reading if you are interested in having this one in your developer toolset implemented as a Class with separate methods to encrypt and decrypt a block of information (even if it uses the same function in both cases).
