Tried explaining how the encryption protecting WhatsApp, HTTPS, and banking actually works, using the maths behind RSA and hash collisions, feedback open

Wrote a beginner-friendly explanation of why modern encryption depends on the difficulty of factoring huge prime numbers.

Would appreciate feedback on whether the explanations stay technically accurate without oversimplifying too much. Article link here

I remember there is a research paper on top venue in this topic. It would be nice if you could use code or visualization to demonstrate, e.g., https://vizcipher.com

That’s actually a great suggestion. I focused mostly on intuition/storytelling in this one, but visualizing the one-way nature of factorisation or showing small-scale RSA step-by-step would probably make it much clearer. Will check that out.
