User can supply only public key and invoke encrypt() or verify() without any problem.
When the user invokes decrypt() or sign() then it will work only after the setkey was
given a private key. This is checked in the actual operation.
So the user is responsible for providing an appropriate key for given operation.
We can split it if you think this is the right thing to do, but currently it works fine.
