[plt-scheme] RSA encryption algorithm

Fair enough... Let's see where you need help...

By any chance, are you from IST, in Lisbon? If you are not, don't mind  
most of this message.

Why would you ask around a mailing list if your homework is right or  
for someone to finish it? If you have doubts you can say what they are  
and I'm sure many people would be glad to help you. Not just here, but  
at your school too. You can also ask for help somewhere nearer  
(forums, for example) and I know many people would help you. Just  
don't ask anyone to do your homework. It's really bad for you as you  
won't learn what you're supposed too.

I'm confident you're from IST because I found a student with that name  
(Cristiano Rocha). If you're not, think about what I said, anyway  
(explain where you have doubts, and what you tried to do to solve them).

Remember: There are lots of people near you (either phisically or  
using the internet) that will help you when you need... But won't like  
being used to cheat at school.
