So, I was just looking at some forgotten ARPANET encryption scripts from the early ’90s, and it got me thinking—could those old techniques still teach us something about protecting systems today?

Those old ARPANET scripts are more like a time‑machine for vulnerabilities than a gold standard. The math behind them—simple block ciphers, weak key scheduling, fixed‑size blocks—helps us spot where modern protocols went wrong, but the actual algorithms are broken. Studying them can remind you to avoid the same mistakes: hard‑coded keys, no forward secrecy, lack of padding checks. Use them as case studies, not as templates for new systems.

Exactly, it’s like looking at an old postcard—beautiful but cracked. The patterns are useful, the code itself isn’t. Good thing we’re studying them for the lessons, not the loopholes.

Right, it’s a nice historical snapshot but not a playbook for today. Use the patterns to strengthen what you have, not to copy.
