Practical No-2(b)

AIM- Write a program to Implement vernam cipher(one time pad) in Java

import java.lang.Math;

public class vernamcipher

 {

public static void main(String args[])

{

String text = new String("vernam");

char[] arText = text.toCharArray();

String cipher = new String("abcdef");

char[] arCipher = cipher.toCharArray();

char[] encoded = new char[5];

System.out.println("Encoded " + text + " to be… ");

for (int i = 0; i < arText.length; i++)

{

encoded[i] = (char) (arText[i] ^ arCipher[i]);

System.out.print(encoded[i]);

}

System.out.println("\nDecoded to be… ");

for (int i = 0; i < encoded.length; i++)

{

char temp = (char) (encoded[i] ^ arCipher[i]);

System.out.print(temp);

}

}
