socket error in python 2.7, sending public rsa key to client -

i'm programming client-server communication encrypted rsa, using tcp sockets. generate public , private keys, when want exchange public keys between client , server error:

typeerror: must convertible buffer, not publickey

this server code:

import socket import rsa  print "generating keys" (public, private) = rsa.newkeys(1024, poolsize=2) print "keys generated."  tcpsocket = socket.socket(socket.af_inet, socket.sock_stream)  tcpsocket.setsockopt(socket.sol_socket, socket.so_reuseaddr,1) tcpsocket.bind(("0.0.0.0", 1025))  tcpsocket.listen(1)  print "waiting client..." (client, (ip, port)) = tcpsocket.accept()   print "connection received from: ", ip   client.send(public) #this error 

i've tried line too:

client.send(str(public)) 

with can send public key, can't use encrypt data (because public key string).

thank !

you can use pickle or cpickle:

import cpickle to_send=cpickle.dumps(the_key) sock.send(to_send) 

and unpickle it:

import cpickle s=sock.recv() key=cpickle.loads(s)
