Comment:
In the associated branch, I've added RSACryptosystem to the global
namespace. Is there any reason why this is a bad idea?
!BlumGoldwasser, the public key system already included with Sage, has a
very similar API to RSACryptosystem. There are a few differences:
* In RSACryptosystem, I combined the `public_key` and `private_key`
methods into a single `calculate_keys` method. This is because the
exponent `e` would have had to be calculated independently (and
identically) in the two methods. In !BlumGoldwasser, the keys can more
naturally be calculated independently.
* I am missing a `random_key` method. This would be an easy addition, but
I'm not sure how valuable it is; for RSACryptosystem it would only need to
find two primes, and plug them into `calculate_keys`.
