[pycrypto] Public key algos usage

[Lorenz Quack]

Hi Stefano,

As far as I know the API remains the same whether the key is a private/public key pair
or only the public key. So this should work (However, I didn't test this code):

 >>> message = "this is a secret"
 >>> pub_key = key_pair.publickey()
 >>> cipher_text = pub_key.encrypt(message, "")

I also think that the API-Reference [1] is fairly accurate.

I hope that helps. If not, maybe you show some code how you try to use it.

yours
