The Biggest Security Myth I Believed as a Beginner

A beginner's misconception about prioritizing encryption algorithms over overall software security architecture led to a shift in focus towards making hundreds of small engineering decisions that work together for better security. This change in perspective improved the design of a Windows desktop security application. The lesson learned is that great security software is built by making many small engineering decisions rather than just choosing the most complicated cryptography. This mindset change is crucial for building secure software. The author now focuses on what happens if someone gets access to the computer, rather than just choosing the strongest encryption algorithm.
