Digraph Cipher; Homophonic Cipher; Playfair Cipher; Vigenère Cipher. Mary Queen of Scots famously used a mono alphabetic cipher with several variations that was incredibly difficult, however when it was finally broken, the messages therein gave the evidence needed by her enemies to sentence her to death. In contrast to codes, ciphers are based on syntax, or symbols. The reason this is so secure is that mathematically it is very difficult to find divisors of large numbers. For everyday life, however, codes are slow and making a code book is cumbersome. The keyword is only five letters long, so for the sixth letter of the message a C cipher is used again. Substitute your plaintext letters with other letters, images, or codes. Its key is simple: each letter of the alphabet is replaced with the following letter, so A is replaced with B, B is replaced with C, and so on. All Enigma machines were identical, and knowing the initial configuration of the wheels inside was the key to enciphering messages. SUBSTITUTION CIPHERS A substitution cipher is a method of encryption where each letter in the alphabet is associate with a unique letter, word, or even symbols. If the rearrangement rule is complex, it might seem very difficult to decipher, however, with modern algorithms on the computer, it can be easily deciphered. This particular cipher involves the use of some key, essentially in a book.
