The next era of encryption starts with knowing what you protect.
Post-quantum security sounds distant. The first useful skill is surprisingly practical.
The signal
In August 2024, NIST released its first three finalised post-quantum cryptography standards. They address key establishment and digital signatures, with algorithms designed to resist attacks from future quantum computers. This is an explainer of that milestone, not a claim that today’s encryption has suddenly stopped working.
Our take: start with the map
Before a team can plan a migration, it needs to know which systems use cryptography, who maintains them and how long the information must remain confidential. That makes inventory, documentation and careful change management useful skills alongside the mathematics.
A small exercise
Draw three boxes: browser, website and database. Mark where data travels and where it is stored. Ask what establishes the website’s identity and which team owns each connection. Do not invent your own encryption scheme; use this as an exercise in understanding dependencies.
