I would like to know how to find the keyword of the Playfair cipher, given some ciphertext and the corresponding plaintext. In first step, construct a modified table of PF cipher Since we already have Caesar cipher, it seems logical to add the Vigenère cipher as well. Create a 5 x 5 table populating each cell with a capital letter in alphabetical order, row-by-row, from left to right, as seen above. Here is the calculator, which transforms entered text (encrypt or decrypt) using Vigenere cipher. Next we take the plain text two characters at a time, and then draw a rectangle around then, and the other letters which bound the rectangle are then used. The technique encrypts pairs of letters (bigrams or digrams), instead of single letters as in the simple substitution cipher and rather more complex Vigenère cipher systems then in use. The Playfair Cipher requires paired letter input, so when the text length is odd, a padding character is typically added to complete the final letter pair. The key might be any word or phrase. Unlike simpler substitution ciphers like the Caesar cipher or the monoalphabetic cipher, the Playfair cipher encrypts digraphs (pairs of letters) instead of Ø Polyalphabetic Cipher is a substitution cipher in which the cipher alphabet for the plaintext alphabet may be different at different places during the encryption process. In this work, the modified Playfair cipher and two modifications of the RSA will be made to increase the level of security and reduce the time required for encryption and decryption. The Playfair cipher or Playfair square is a manual symmetric encryption technique and was the first literal digraph substitution cipher. Invented by Lester S. 1 Working of 2D Playfair Cipher 2D Playfair cipher is a key substitution and block cipher. It is due to the fact that keyword cipher is mono alphabetic and thus can be cracked using frequency analysis. As technology evolves, so do the tactics employed by cybercriminals, making When it comes to wireless communication, RF modules are indispensable components that facilitate seamless data transmission.
