Brussels launched an age checking app. Hackers took 2 minutes to break it

The EU's mandated age-verification app was broken in under two minutes by security researchers — a case study in what happens when regulation outruns engineering competence. The app was collecting far more data than needed, on top of being trivially bypassable. A cautionary tale about compliance theater vs. actual privacy-preserving design.

Quantum Computers Are Not a Threat to 128-Bit Symmetric Keys

Cryptographer Filippo Valsorda cuts through quantum FUD: Grover's algorithm only halves the effective key space, making 128-bit symmetric keys still computationally safe even against large quantum computers. Clear, rigorous, and corrects a lot of half-baked takes in the "post-quantum" discourse. Essential reading before you over-engineer your encryption stack.
