The lack of clear images of the original ciphers, combined with the large quantity of numerals, has led to numerals being misprinted or omitted in many sources. The Beale Papers text, on pages 20 to 21, gives an alleged translation of the second ciphertext, but it has nine differences from the actual one.
In cryptography, a Caesar cipher, also known as Caesar's cipher, the shift cipher, Caesar's code, or Caesar shift, is one of the simplest and most widely known encryption techniques. It is a type of substitution cipher in which each letter in the plaintext is replaced by a letter some fixed number of positions down the alphabet.

It was employed extensively by Nazi Germany during World War II, in all branches of the German military. The Enigma machine was considered so secure that it was used to encipher the most top-secret messages. [1] The Enigma has an ...
