make a cesar cipher statistical attack using c++

Answer 1

#include <iostream>

#include <string>

#include <algorithm>

using namespace std;

char encode(char, int);

char decode(char,int);

string encoding(string,int);

int main()

{

string message;

string deco;

string enco;

cout<<"Input text: ";

getline(cin,message);

int size;

cout<<"Enter cipher key: ";

cin>>size;

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

enco=enco+encode(message[i],size);

}

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

deco=deco+decode(enco[i],size); //appending result

}

cout<<"Encoded Message: "<<enco<<endl;

cout<<"Decoded Message: "<<deco<<endl;

return 0;

}

char encode(char c, int seed){

return (int)c+seed;

}

char decode(char c, int seed){

return (int)c-seed;

}
