Question

d. Write a function Encode as follows:
• // Return M^e mod PQ
• int Encode (int M, int e, int PQ);

e. Write a function Decode as follows:
• //Return C^d mod PQ
• int Decode (int C, int d, int PQ);

f. Verify that RSA algorithm works, i.e.,
• int M;
• /* M is an integer that is smaller than PQ */
• cout <<"Enter an integer that is smaller than"<< PQ;
• cin <<M;

• C=Encode (M, e, PQ);
• M1=Decode (C, d, PQ);
• assert (M==M1); //Note: include assert.h header file to use this
//macro/function.
