Rijndael?  Sounds dutch.  What module is that?
Ooh its a C++ lib maybe.  I'm still wishing for functions in the
Python library that have a good reputation (everybody bashes the
"rotor" module I like).

import pycrypt   # wishlist module
secret = 'mysecret'
encoded = pycrypt.encrypt('message', secret)
decoded = pycrypt.decrypt(encoded, secret)
assert( decoded == 'message')

That would be nice.  With um Rijdael, if that is a cool one?

I have a setup where I use rotor and some others and base64
sequentially (has to be normal characters).  Is that bad?

And that is encrypted of course?  Then what could be your problem?  As
long as they don't guess your secret of course.  How do you distribute
the secret.  Email is out.  Snailmail too maybe.
