[pycrypto] Exporting/importing RSA publickeys

[death]

i'm just wondering is there a way to import AND export the public keys
from RSA so i can, send the public key over a socket, import it on the
otherside so i can create a "secure" socket ( i know authentication is
not done in this process ). 
the socket is still subject to a MIM attack, but this is not the point
at the moment 

it could be my inability to read the documentation but i found no way to
dump the key, and import it again.
