Teddy asked Kevin Sands:

what kinds of codes and puzzles did you use in The Blackthorn Key series? I would like to get a better grip on the ciphers you use!

Kevin Sands Substitution ciphers of various sorts, reverse writing, Vigenere, atbash, Polybius square, Cistercian numbers, Ave Maria, scytale, symbology, steganography, plus riddles and visual puzzles. Maybe some others? I might be missing some, there were a lot.
