I have completed the Caser cipher, translationMatrix interface and the Cipher class. I am lost on how to start the substitution. 

Where would I start to implement this cipher properly?

 

NH 2 3 5 6 7 8 TranslationMatrix.java no usages public class Substitution implements Translation Matrix { Caesar.java } 1 usage @Override public String translate(String[] words) { Substitution.java return null; Translator.javax Cipher.java Vigenere.java
