What’s going on guys?

I have a short encryption tutorial for you today, which is kind of a continuation from my recursive file encryption post a while back.

In that post we did encryption of multiple files recursively, while this time we’ll be doing in-memory AES encryption over the network.

This tutorial will be limited in scope in the sense that we’ll only send the data one way for now (from client to server); however, the plan is to incorporate it into my python control server series soon.

We’ll be using Python 3 for this tutorial (as one should by now). For the encryption side of things we’re using pyAesCrypt, which can be easily installed with pip by running the following command in a terminal:

python -m pip install pyaescrypt

In the video above, after going through the code and explanations, I also fire up wireshark and show the difference from both a plaintext server/client traffic to the encrypted data we’re implementing here.

What’s going on guys?

We’re off to another series: Python Control Server.

Yes, there’s three series going on at once in the blog, so what! 😀

I like having multiple things going so that I don’t have to think much whenever I have some free time to code. I can just sit down and choose whichever series/project to work on at the moment.

Anyway, many people emailed me to post my old videos (from like 10 years ago) from this same series – written in Python 2.X.

However, with Python 2.X reaching end of life in January 2020, I figure: Why not just redo the whole thing in Python 3?

It’s also worth mentioning that some of the libraries I used back then have not been properly ported over to Python 3. Overall it just makes a lot of sense to redo the project using more current libraries.

Control Server

Why make a Python Control Server?

For many (ahem, very educational) reasons of course! Like for example, we are two days away from Christmas and many people enjoy taking vacations around this time. Well, why not setup a nice control server to have access to your systems while your away?

Sounds like a good idea time to me!

About Christmas though, I had my first batch of family visiting and let me tell you… its rather easy to get a cold when there’s a lot of people in the same household for hours at a time. So pardon my voice in the video.

What’s going on guys?

We’re continuing with our Ionic 4 series today.

As explained in part one, we’re making a simple card matching game in order to learn the different components of the Ionic framework.

If you’re clueless about the Ionic framework, you should go check out the first part where I explain it in more detail.

I won’t ramble for too long in this post (as usual), since I explained that I’m not planning on covering code in these blog posts for Ionic – that’s what the videos are for anyway alright.

Instead, I’ll leave a summary of what goes down in this part.

Coding Summary

In this second part, we’ll get our card matching game to a playable state.

Basically, by the end of it, you’ll be able to select both cards and we’ll put conditions in place to check if the selected cards match or not.

[ Part 1 (Introduction) – Part 2 – Part 3 – Part 4 ]

Howdy! How you doing today?

Welcome to another series of videos!

This time we’re diving into hybrid applications with Ionic 4.

We’ll be developing a simple card matching game that you can run in many different platforms like: Android, Apple devices (iPhone, iPad, etc.) and basically anything that runs HTML, CSS and JavaScript.

I’m always excited to learn new technologies and of course, share the knowledge with you guys in my path moving forward. But why Ionic?

Ionic Framework

With the explosion of smartphones and mobile applications of this decade, there had to be new developments for programmers as well. Why?

Well, imagine that programmers would have to learn how to make applications for Android, then for Apple devices, then Microsoft products and the list goes on… something had to be done.

It turns out that hybrid applications would make our lives incredibly easier by allowing programmers to use a single codebase for applications.

All thanks to frameworks like Ionic, among others, usually JavaScript-based.

Now that you know more about the framework and its capabilities, let’s take a look at the required software for this project.

Hello there, how’s it going? (Download script here)

In today’s post, I want to show you a short script to do recursive file encryption in Python 3 – using pyAesCrypt with AES encryption.

Its amazing how powerful this programming language is, really. This is mostly what I wanted to show you guys this time and one of the main reasons I keep coming back time after time to Python.

Using about 20 lines of code, we’re able to encrypt many files in seconds.

Anyway, this post will basically function as a introduction into encryption in Python 3. I had many posts about using encryption in my previous blog with PyCrypto – and I’m still a big fan. However, with Python 2.X in the midst of sunsetting, I figure its time to start looking at newer libraries.

I know there are recent forks for PyCrypto such as PyCryptodome, but in any case, its always good to have some variety in your arsenal.

With that said, pyAesCrypt seems to work rather seamlessly and provides a few different options for functionality – file encryption, stream encryption and in-memory encryption (sounds spicy ay?).

Encryption Using pyAesCrypt

Before we get into the recursive file encryption script, let’s take a look at their brief, yet effective example of basic file encryption:
