What’s up guys?

In this part we’ll be implementing file transfer and encryption.

I use these programs on my own system and you absolutely have to be able to download and upload files in order to get anything done.

Now some of you might remember in part three I mentioned that our encrypted channel wasn’t stable enough to handle several megabytes of data without any mishaps.

Because of that, I had to implement file encryption and decryption in the client as well, since we’re already working with pyAesCrypt anyway.

This allows us to, at the very least, encrypt files locally before sending them over a standard tcp tunnel – or keep them encrypted on the system.

Like much of the functionality we’re going through here, these functions could be copied and used in other code without much hassle.

File Encryption

I’ve already made some posts regarding file encryption using pyAesCrypt in the blog, most notably: recursive file encryption in Python 3.

I recommend to check that one out if you haven’t seen it yet.

In any case, file encryption with pyAesCrypt is pretty straightforward. We are basically working with the following methods:

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.
