In this article, we are going to learn three Cryptography Techniques: Vigenére Cipher, Playfair Cipher, and Hill Cipher. I have a project to make an encryption and decryption for string input in java. The content must be between 30 and 50000 characters. Do you need your, CodeProject, As per Wikipedia, Hill cipher is a polygraphic substitution cipher based on linear algebra, invented by Lester S. Hill in 1929. Therefore, making the key matrix default will be more convenient. Hill Cipher in Java or C. You must write a program in either Java or C that encrypts the alphabetic letters in a file using the Hill cipher where the Hill matrix can be any size from 2 x 2 up to 9 x 9.

To encrypt a message, each block of n letters (considered as an n -component vector) is multiplied by an invertible n × n matrix, against modulus 26. In classical cryptography, the Hill cipher is a polygraphic substitution cipher based on linear algebra. The user should enter the message and the key matrix (2x2 or 3x3) to the program as ROW matrix not a column!. Provide an answer or move on to the next question. This implementation follows the algorithm recipe at Crypto Corner here. The hill cipher encryption technique uses mathematics to encrypt the plain text. This article do not cover algorithm behind the Hill cipher. Invented by Lester S. Hill in 1929 and thus got it’s name. *; class Basic{ String allChar="ABCDEFGHIJKLMNOPQRSTUVWXYZ"; boolean indexOfChar(char c) { for(int i=0;i < allChar.length();i++) { if(allChar.charAt(i)==c) return true; } return false; } } class PlayFair{ Basic b=new Basic(); char keyMatrix[][]=new char[5][5]; boolean repeat(char c) { if(!b.indexOfChar(c)) { return true; } for(int i=0;i < keyMatrix.length;i++) { for(int j=0;j < keyMatrix[i].length;j++) { if(keyMatrix[i][j]==c || c=='J') return true; } } return false; } void insertKey(String key) { key=key.toUpperCase(); key=key.replaceAll("J".
