Vigenere Cipher C++ code

Code

Vigenere Cipher C++ code

Here we assume that plain text length is equal or more than key length

#include<iostream>

#include<string.h>

using namespace std;

class VigenereCipher

{

char plain[33],cipher[33],key[11];

int i,j,pl,kl;

public:

VigenereCipher(){ }

void GetPlain()

{

cout<<"\t\t\t ***ENTER PLAIN TEXT***"<<endl;

cin>>plain;

pl=strlen(plain);

}

void GetKey()

{

cout<<endl<<"\t\t\t ***ENTER KEY***"<<endl;

cin>>key;

kl=strlen(key);

}

void KeyManip()

{

for(i=0;i<pl;i++)

{

key[i]=key[i%kl];

}

void Encryption()

{

for(i=0;i<pl;i++)

{

cipher[i]=(((plain[i]-97)+(key[i]-97))%26)+97;

}

void DisplayCipher()

{

cout<<endl<<"\t\t\t ***CIPHER TEXT IS***"<<endl;

for(j=0;j<pl;j++)

{

cout<<cipher[j];

}

cout<<endl<<endl<<"\t\t\t+++END OF PROGRAM+++";

}

};

int main()

{

VigenereCipher v1;

v1.GetPlain();

v1.GetKey();

v1.KeyManip();

v1.Encryption();

v1.DisplayCipher();

return 0;
