RSA uses computation in set Z_n={0,1,2,…,n-1}, where n is product of two fairly large prime numbers p and q. Here is the encryption and decryption algorithms for RSA Let n=pq (as indicated above), where p and q are prime numbers. Find two integers in Z_n such that ab≡1 mod(p-1)(q-1)) Encryption function e: Let x be a word (message). Then e(x)=x^b mod n Decryption function d: Let y be an encrypted message with function e. Then x=d(y)=y^a mod n In this project you will implement function e and d. I will provide a text message and you should be able to encrypt the message by using function e and decrypt the encrypted message by using function d.
