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:

What’s up guys? Got a sweet and short tutorial for you today!

Before we begin, I want to clarify this tutorial is for Windows 10. I’m pretty sure it should work for other Windows version as well. I will probably make a Linux version for it soon too, so watch out for it! If you’re interested in it for a different operating system, leave a comment below.

Also, if you just want the script and don’t care about the article, head all the way down to the end of the post where you will find a download for either the Python 2.7 version or Python 3 scripts. Please watch the video though, so you know the instructions to get the script working (its easy!).

Yesterday I was looking for a way to automatically change the background / wallpaper of both my monitors using a Python script (every X seconds).

Although I was able to find a few sources to change the background, it would change the background for both of my monitors at once.

I then ran into this stackoverflow post, where a user replied suggesting merging two images into one and then setting the background as a tiled image using Win32 API functions – thank you fine sir.

Well, luckily I had some previous experience with Win32 API and its functionality under Python and I also had some experience working with images in Python using Python Imaging Library (PIL).

I decided this could be a fun little challenge and set out to do it. 😉
