SecureFromScratch

At Secure From Scratch, we teach secure coding in high schools and academic institutions. We tailor each course to the programming languages students already know—so they can learn secure coding effectively and fast.

Our vision is to build complete programming courses with security baked in from the start.

This repository contains all the materials we use in our workshops. For the Java secure coding course, there’s a supporting YouTube playlist (soon to be translated to English). We aim to create video content for all materials presented here.

Your sponsorship helps us make security education accessible, practical, and language-specific—empowering the next generation of developers to write secure code by default.

@SecureFromScratch

Our goal is to reach $5,000/month to scale our secure coding initiative. Sponsorships will fund the development of full-language course tracks (Java, C#, Node.js, Python), high-quality educational videos, translations.
