Question

Perform encryption and decryption for the RSA algorithm using these parameters: p = 13; q = 19; e = 5;
Plaintext should be the first three letters of the month you were born (convert letters to the values 0-25). Note you need to do three encryptions. Show how decryption works.
The above calculation is performing a cipher on the alphabet. How does this method compare with a classic cipher?

Answer 1

The above is the solution for one alphabet M for the birth month MAY
Similarly we can proceed for further(3-times) for the other 3-alphabets
