Background Theory. He also perfected a useful communication code that could for sending messages over long distances. To give a small level of encryption, this table can be randomized and shared with the recipient. To install it, use pip install pycipher.To encipher messages with the Polybius square cipher (or another cipher, see here for documentation): >>>from pycipher import PolybiusSquare >>>p = PolybiusSquare('phqgiumeaylnofdxkrcvstzwb',5,'ABCDE') >>>p.encipher('defend the east wall of the … In order to fit the 26 letters of the alphabet into the 25 spots created by the table, the letters i and j are usually combined.
