Getting started with encryption of documents

What is the problem

If you work with sensitive (human) data (e.g. anything that contains an identifier of an individual), you occasionally want to share that data. The most straightforward way to do so is to send them by email (and yes - we are all guilty of that!). The problem arises, if the data get into wrong hands. Let's say you send the email accidentally to the wrong person. Or worse, without your knowledge, the email gets into the wrong hands.

The good news is, that there is a secure & handy solution for this. But let's first have a look at some other solutions.

What about dropbox and other file hosting systems? ❌

The Revealing Module Pattern in Javascript

Zach Caceres

Javascript does not have the typical 'private' and 'public' specifiers of more traditional object oriented languages like C# or Java. However, you can achieve the same effect through the clever application of Javascript's function-level scoping. The Revealing Module pattern is a design pattern for Javascript applications that elegantly solves this problem.

The central principle of the Revealing Module pattern is that all functionality and variables should be hidden unless deliberately exposed.

Let's imagine we have a music application where a musicPlayer.js file handles much of our user's experience. We need to access some methods, but shouldn't be able to mess with other methods or variables.

Using Function Scope to Create Public and Private Methods

This is a quick tutorial explaining how to get a static website hosted on Heroku.

Why do this?

Heroku hosts apps on the internet, not static websites. To get it to run your static portfolio, personal blog, etc., you need to trick Heroku into thinking your website is a PHP app. This 6-step tutorial will teach you how.
