Not a lab — a read. Myths debunked, the physics of why brute force actually fails, what quantum computers really threaten, and where all of it shows up in a tool you already use: SSH.
Done
Physics, not vibes.
Every myth in this lesson collapses the same way: someone treated a security property as a feeling instead of a number. AES-256 isn't safe because it "seems strong" — it's safe because the energy bill for breaking it exceeds what the universe has to spend. RSA isn't at risk from quantum computers because they're "powerful" — it's at risk because Shor's algorithm changes the actual math problem being solved. Hold onto that instinct. It's the same one every live-break in this track's labs was building: don't assume, check the number.
