> HOW THIS WORKS

Hey, I'm Bestie. Here's how this works:

1. 1. Type your secret in the MISSION BRIEFING box.
2. 2. Pick a CIPHER. I'll hide your message in code.
   CAESAR slides each letter forward. HI becomes KL.

   ATBASH mirrors the alphabet. HI becomes SR.

   SUBSTITUTION scrambles all 26 letters. Trickier.

   RANDOM lets me pick.
3. 3. Hit DEPLOY. Your message turns into a puzzle.
4. 4. Hit COPY LINK to text it, or PRINT WORKSHEET to hand it over on paper.
5. 5. When they send one back, paste it in PASTE A MESSAGE TO DECODE and hit DECODE. Crack their code.

Back-and-forth. Like text messages, but secret.
