Instructions Modify the attached program to add RSA encryption and decryption. The following variables are used m- plaintext message c-ciphertext message d- private key e- public key n-a large special number For encryption: me mod n The program does encryption and prints the ciphertext. Now add the code for decryption. For decryption the computation to be done: cd mod n The above computation returns a Biglnteger. So you have to convert that to a String by calling convertBigIntegerString) method. Finally, print the string after decryption. A block diagram for public key encryption for PDF format is also attached for your reference. Submit .java file before the deadline. B public-key-encryption-diagram....
