Unless we know the M08 cipher alphabet by heart, we should create one. Since it's a pretty long message, you may want to add '/' between each two-digit (each two-digit represents a letter). Here's an example of a message you want to decipher:
#Alphabet cipher full
Continue in this way until you get your full code. The third letter is a 'h' which corresponds to '10'. The second letter is 'o', and that corresponds to the '17' on the key.
#Alphabet cipher code
Therefore, the first two-digit of the code is a '12'. The first letter is 'j', and we can see it corresponds to the '12' on the key. To encipher the message, we must use the key. Note that you should write all numbers as two-digits, adding a '0' in front if necessary. Continue the number until we reach '26', at which point we loop back to '01' until we finish the key. Then, put the number on our key and write it directly below the key's letter. To create a cipher alphabet, write the alphabet out. We should write out the cipher alphabet, using A=03 also known as A03. Also, A=03 can be written as B=04, C=05, as the letter increases at the same rate as the number. Note that A=01 is the letter-to-number cipher and is easy to break. For the sake of simplicity, we'll have A=03, but A can equal anything from 1-26. The recipient of the message will see a string of numbers, with each number standing for a letter.įirst, we must choose a key. Using the key M=8, by the order of numbers and the alphabet the cipher can continue as N=9, O=10, P=11, etc.
For example, in the books Christopher and Master Benedict use the key M8, to show that M=8. The cipher requires the user to choose a substitution key to show how the cipher is enciphered and deciphered. The key consists of a letter, followed by the number by which it stands for in the code. In theory, the substitution cipher is quite simple. However, they differ in the sense that the letter-to-number cipher has a fixed substitution of a=1, b=2, z=26, etc meanwhile, the book's substitution cipher can be coded in 26 different ways (for each letter of the alphabet).Ī substitution cipher looks like a string of numbers, headed by a key. The substitution cipher used in the books is very similar to the letter-to-number cipher, as they both replace a letter in the alphabet with a number.
For example, the Vigenère cipher uses multiple Caesar shifts in order to code a message.
This is the opposite of a polyalphabetic cipher, which uses multiple different ciphers to encode a single piece of plaintext. This means that each letter of plaintext is replaced with only one other ciphertext.
#Alphabet cipher series
While the umbrella term 'substitution cipher' is extremely broad, the type of cipher used in the book series is a monoalphabetic cipher.
