The whole series
Every week of White-Hat Sundays
12 weekly sessions, each its own step. Built for ages 9 to 13. Every week builds on the last, so the learning is a real climb, not a set of one-off games.
The pledge, and what ethical hacking is
A white hat finds weaknesses to FIX them, only ever with permission. Sign the pledge, then train the careful eye that spots what is not safe.
Everything is numbers, and the Caesar cipher
Letters are numbers underneath, so shifting them hides a message. Make and break your first cipher.
The one-time pad (XOR), unbreakable
One secret key, used once, makes a message mathematically unbreakable. Feel why.
Clock (modular) arithmetic
The maths behind modern crypto: numbers that wrap around like a clock.
Share a secret in the open (Diffie-Hellman)
Two people agree a secret while everyone listens, and the listener still cannot know it.
Hashing: the fingerprint machine
Check a password without ever knowing it: one-way fingerprints that cannot be run backwards.
Passwords: why they fall, how to build strong ones
Feel the crack race: length beats cleverness, and a passphrase beats both.
How the internet carries a message
Your message rides in addressed parcels, hop by hop, across the world.
The secure handshake
How two machines that never met agree to speak privately, in front of everyone.
Where it leaks: your footprint, and the imposter
What the internet already knows about you, and how an imposter slips into a network.
Break in safely, then defend
A break-in is a chain; a defender breaks one link. Attack the practice range, then defend it.
Family Showcase Day
Each learner runs a station and teaches their family one real security idea.
