Do you mean 50 numbers of some given size, of do you mean a number with
50 digits. It's not the same thing... I'm sure you can change my code
from 27 digits to 50 it you wish. Making it into a function that takes
length as a parameter isn't exactly rocket science either...

Encryption is a very tricky subject, and I fear that Python is all
too slow to be really useful for real encrytion. Maybe it would be
more worthwhile to study some of the already existing encryption
libraries for python that are wrappers to C libraries, and to make
some useful application that really uses one of them. I think that's
the practical way to do crypto with Python. See
