The message M in the RSA system can be any number between 0

The message M in the RSA system can be any number between 0 and N - 1. The coded message R is also a number between 0 and N - 1, but can it be any such number? Justify your answer.

Solution

yes it can be.

if we take message M is:854623

then the coaded message is 965734

it is just nothing but add +1 to each character.

then codeed message is:965734.

    if the massage is:999999

then we can write coaded message as:10-10-10-10-10-10 or any oher coads.
