<PRE>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
