A book cipher is an example of a homophonic substitution cipher, since the same word or letter can be encoded in different ways. For example, the word THE could have been translated into 1:4, 2:3 or any of the other places where it has been used.

WebThe order of the letters in the grid can be modified using a key to generate a deranged alphabet. The encryption phase is a substitution of each letter by its coordinates (row, column) in the grid. Example: D is located row 1, column 4, so coded 14; C is located row 1, column 3, it is coded 13. The ciphered message DCODE is then 14,13,35,14,15. WebTranslations are done in the browser without any server interaction. This is an Open Source project, code licensed MIT.
