[Botan-devel] RSA key size

Security is the reason for that particular size (though realistically it should
probably be 1024 if I'm actually trying to keep people from shooting themselves
in the foot).
I would not be willing to make a strong bet that the RSA keygen routines work
correctly for very small bitsizes (I've just made a note to myself to check on
this). So if you need smaller keys, I'd recommend leaving the check in, and
changing the constant to something like 128 (I've also made a note to move that
magical 512 from a constant to the Conf:: subsystem, so it can be changed or
disabled without having to actually edit the code).
