Kiwicon 2038AD - Badge Challenge - Part 3
Two more puzzles.
The code in the kiwicon guide book is a simple substitution cypher. this can be solved by looking at the frequency of letters. In english the letter E is the most common. The most common letters in order are e-t-a-o-i-n. So popular is this method of analysis, there is software than can do this for you.
If you solved the code in the book and sent a txt to the phone number then you got a link to a pdf file full of symbols.
That PDF is just another substitution cypher.
If you solve that then you get a link to some audio.
That audio is encoded with Kansas City Standard.
