Then you run your message through the tabula recta, a table where you use the letter you want revealed and the letter in your running key to pick the letter in your encryption. This page describes how to use the Index of Coincidence to determine the key length for the Vigenere, the same process can be used for the Porta. Here, we can see Cipherface mapping out the encrypted message using this method. Posted on 18/03/2012 15/02/2019 by Jinavie.

References § [1] The ACA(American Cryptogram Association) has a good description of the encryption/decryption process. 4. Decode The tabula recta used with the Beaufort cipher is called a Beaufort square, and is similar to a Vigenere square except it’s arranged in reverse order, with the letter Z coming first, and letters cascading in reverse alphabetical order from there. However, the table was first used by German author and monk Johannes Trithemius in 1508, which it was used in his Trithemius polyalphabetic cipher. How do you solve a tabula recta?

The tabula recta is often referred to in discussing pre-computer ciphers, including the Vigenère cipher and Blaise de Vigenère's less well-known autokey cipher. if you have the first key letter of a length 7 key, then the 1st, 8th, 15th, 22nd etc. It's main weakness is that partial keys can be tested i.e. 2. The reason Autokey is more difficult to break than Vigenere ciphers is that the key does not repeat, which means the Kasiski test fails, and the Index of Coincidence can't be used to determine the key length. I've been using a Tabula Recta for my passwords and used a Python script someone wrote to generate the table and do table traversal. Diese Funktionen können natürlich unabhängig voneinander genutzt werden. The Challenge. The keystream is taken from this book, choosing a page and line number to start at.

Trithemius used the tabula recta to define a polyalphabetic cipher which was equivalent to Leon Battista Alberti's cipher disk except that the alphabets are not mixed. It has the alphabet written out 26 times in different rows, each alphabet shifted cyclically to the left compared to the previous alphabet, corresponding to the 26 possible Caesar ciphers. 3.
