Warning This Section Does Contain Spoilers For Solving The Cyphers For Episode Three
The Binary code is a code that the computers recognize using only 1's and 0's. Binary cypher has different code of 1's and 0's for upper and lower case letters. Mr. James' letter has many L's and O's replaced with 1's and 0's. When putting all of these numbers written down in order and separating into sections of 8 for a binary sequence we receive a binary cypher code.
01001001 = I
01100111 = g
01101111 = o
01110100 = t
01001101 = M
Our binary cypher reads: I got M
Transposition cyphers, or anagrams, are where the letters are jumbled up together. Instead of replacing characters with other characters, this cypher just changes the order of the characters. Typically the text to be encrypted is arranged in a number of columns. These columns are then recorded resulting in encrypted text e.g. (1, 2, 3, 4, 5) (4, 5, 3, 2, 1). To decrypt you need to work out the number of columns usually based on a common factor of the total number of characters in the text and then rearrange the columns. In the letter from JWJ two words are such an anagram, transposition, cypher. "Mooded" and "Scungy". When rearranged these words spell: Doomed Cygnus.
