Binary code breaker pdf
Bacon's cipher or the Baconian cipher is a method of steganography a method of hiding a secret message as opposed to just a cipher devised by Francis Bacon in To binary code breaker pdf a message, each letter of the plaintext is replaced by a group of five of the letters 'A' or 'B'. This replacement is a binary encoding and is done according to the alphabet of the Baconian cipher from the Latin Alphabetshown below:.
A second version of Bacon's cipher uses a unique code for each letter. In other words, IJU and V each have their own pattern in this variant:.
The writer must make use of two different typefaces for this cipher. Binary code breaker pdf preparing a false message with the same number of letters as all of the As and Bs in the real, secret message, two typefaces are chosen, one to represent As and the other Bs.
Then each letter of the false message must be presented in the appropriate typeface, according to whether it stands for an A or a B. To decode the message, the reverse method is applied. Each "typeface 1" letter in the false message is replaced with an A and each "typeface 2" letter is replaced with a B.
The Baconian alphabet is then used to recover the original message. Any method of writing the message that allows two distinct representations for each character can be used for the Bacon Cipher. Binary code breaker pdf himself binary code breaker pdf a Biliteral Alphabet  for handwritten capital and small letters with each having two alternative forms, one to be used as A and the other as B. Because any message of the right length can be used to carry the encoding, the secret message is effectively hidden in plain sight.
The false message can be on any topic and thus can distract a person seeking to find the real message. The word 'steganography', encoded with padding, where text in italics represents "typeface 2" and standard text represents "typeface 1":.
Some proponents of the Baconian theory of Shakespeare authorshipsuch as Ignatius L. Donnelly and Elizabeth Wells Galluphave claimed that Bacon used the cipher to encode messages revealing his authorship in the First Folio.
However, American cryptologists William and Elizebeth Friedman refuted the claims that the works of Shakespeare contain hidden ciphers that disclose Bacon's or any other candidate's secret authorship in their The Shakespeare Ciphers Examined Typographical analysis of the First Folio shows that a binary code breaker pdf number of typefaces were used, instead of the two required for the cipher, and that printing practices of binary code breaker pdf time would have made it impossible to transmit a message accurately.
