8 hours of advanced C projects: Cyber Security from Udemy

8 hours of advanced C projects: Cyber Security

This is an 8 hour composite course (divided in 13 different 40min videos) containing my best content with regards to Cyber Security. You will get an in-depth knowledge in writing encryption tools, connecting to the Tor privacy network, and how to write safe, un-hackable C code by making a safe string library.

When doing all of this practically, I will explain all the necessary theory while we're coding. So there are no dense sections of heavy theory but you will still learn everything you need in order to fully understand the things we are building. While on this journey, you will also improve your knowledge of some of the more advanced features of the C language. Like how dynamic memory works, how you deal with linked lists, everything about advanced pointers, operating system functions (syscalls) as well as some binary bitwise operations, etc.

You will also learn the basics of Linux file system security and a whole lot more. And, as always, in 1080p resolution. Enjoy.

Best regards,JB

Free previewDo not miss out of the free preview. You can watch the entire first episode (40min. ) for free. That contains the most part of one of my best C projects, the Toralizer. It is a command-line tool which lets you redirect any other Linux command through the Tor network.

Example:bash$ toralize curl http://website-url

This will connect to the Tor privacy network and access the website. This works with any Linux command and we will code this tool from scratch to the finish line, in this course.

PrerequisitesThis is not a beginner course in the C language (I have courses like that too). This is for people who already knows the basics of C and wants to take the next step to intermediate-advanced level knowledge of the C language.

This course is also for C coders who wish to know more about Cyber Security.

The authordr. Jonas Birch has been programming the C language for more than 25 years and he's been teaching for the last 7-8 years. He has a background in the Cyber Security industry and he's a Senior network engineer. His videos are very popular (some are the highest rated courses on Udemy, in its category) and he's got a very soothing voice which is easy for the ears.
