Comment (by nbruin):
Before people spend too much time on the code here: Is there a reasonable
scenario that justifies having this in the library? We're not going to use
it for industrial encryption applications, so I think people think it's
for teaching. However, when I teach RSA, the students have to *see* the
exponentiation and the construction of the moduli. At that point, the fact
that you can do square-and-multiply to do the exponentiation efficiently
is already a worthwhile revelation for them.
So having that all wrapped up in library routines is no help at all.
They're going to have these things in front of them on a worksheet.
Do people have some lower level scenario in mind where it's sufficient for
the students to play around with a crypto "black box"?
I don't mind if it gets included for a good reason, but if the code here
isn't going to be used properly and frequently in teaching I'd rather not
have it in there, because it will take away from the excitement that
students get from implementing their own RSA if there's already such an
implementation available in sage.
