To use RSA encryption on words, the computer first must convert the letter into a number. To do this, it uses a system called ASCII (American Standard Code for Information Interchange) which assigns a decimal value to each letter. Here are the ASCII codes for uppercase letters A-Z: A five letter word was converted to decimal values, then encrypted using the RSA public key e = 5, n = 3953. The encrypted message was: 3544 3192 1669 2639 3181 Decrypt this message back to letters using the private key d = 2297
