Here is the source code of the Java Program to Enode a Message Using Playfair Cipher. The Java program is successfully compiled and run on a Windows system. The program output is also shown below Java Program to Implement Playfair Cipher Algorithm. Last Updated : 28 Mar, 2021. Cipher is an algorithm for encryption and decryption. The cipher text is a process that applies to different types of algorithms to convert plain text to coded text. It is referred to as ciphertext The Playfair cipher is one of the traditional ciphers which comes under the category of substitution ciphers. In Playfair Cipher, unlike traditional cipher, we encrypt a pair of alphabets (digraphs) instead of a single alphabet. In Playfair cipher, initially, a key table is created Implementation of Playfair cipher in Java.

The Playfair cipher was the first practical digraph substitution cipher. The scheme was invented in 1854 by Charles Wheatstone, but was named after Lord Playfair who promoted the use of the cipher. The technique encrypts pairs of letters (digraphs), instead of single letters as in the simple substitution cipher import java.util.Scanner; public class playfair { private String KeyWord=new String(); private String Key=new String(); private char matrix_arr[][]= new char[5][5]; public void setKey(String k){ // This function will take the input key from the user // Then it'll remove duplication of letters from the key // Will add it to the private KeyWord for matrix generation String K_adjust=new String(); boolean flag = false; K_adjust = K_adjust + k.charAt(0); for(int i=1; i<k.length();i++. The Playfair cipher or Playfair square or Wheatstone-Playfair cipher is a manual symmetric encryption technique and was the first literal digram substitution cipher. The scheme was invented in 1854 by Charles Wheatstone, but bears the name of Lord Playfair for promoting its use. The technique encrypts pairs of letters, instead of single letters as in the simple substitution cipher and rather more complex Vigenère cipher systems then in use. The Playfair is thus significantly. // encodes text input using the Playfair cipher // results (both encode and decode) are output with the table // requires a user keyword for the cipher // ues letter 'X' for insertion, I replaces Plaintext is encrypted two letters at a time, according to the following rules: Take the characters in the text (plain/cipher) and make a group of two characters. If the numbers of characters in the text is odd then add a filler letter (usually we use 'x'). Text=HELLO then it would be group a

Playfair is one of the best-known traditional ciphers but it is limited to different aspects such as: white space, numbers and other printable characters. The existing technique is based on the use of a 5 × 5 matrix. This algorithm can only allow the text that contains uppercase alphabets only Playfair cipher is also a substitution cipher technique but it is a bit different than other substitution cipher techniques. Its rules are different. In this cipher, we already know the plain text and the keyword. In this technique, we have to construct a matrix of 5x5 and we have to put each letter of the keyword in that matrix

Playfair is rather more secure than simpler substitution ciphers because it works with digrams rather than single letters, rendering simple frequency analysis moot. Frequency analysis on digrams is possible, but requires considerably more cipher-text than frequency analysis on single letters because Playfair admits 600 digrams whereas simple substitution admits only 26 letters Playfair Cipher Gui Java Code .

Beginning with the letter on the same line as the first letter to crypt The Playfair cipher was the first cipher to encrypt pairs of letters in cryptologic history. Wheatstone invented the cipher for secrecy in telegraphy, but it carries the name of his friend Lord Playfair, first Baron Playfair of St. Andrews, who promoted its use. The first recorded description of the Playfair cipher was in a document signed by Wheatstone on 26 March 1854 Java Program on Caesar Cipher. The Caesar cipher, also known as a shift cipher, is one of the simplest forms of encryption.
