Is there a module to control the SSL handshake in python, Both client side and server? The python default SSL module is great but does the handshake automatic. I was wondering if there is a module that will allow me to do it manual similar to this:
import SSLManuel
import socket
s = socket.socket()
s.connect(("server.com",9999))
ClientHello = SSLManuel.generateClientHelloMessage(ssl=TLSv1_2, cipher="ECDHE-RSA-AES128-GCM-SHA256", server="www.server.com")
s.send(ClientHello)
ServerHello = s.recv()#this would receive the server hello
#This would verify the certificate of the server
if SSLManuel.check_cert(ServerHello) == true:
Pre-Master-Key = SSLManuel.generatePreMasterKey()
ClientKeyExchange = SSLManuel.generateClientKeyExchange(Pre-Master-Key)
ChangeCiherSpec = SSLManuel.generateChangeCipherSpec()
ClientFinished = SSLManuel.generateClientFinished()
Sessionkey = SSLManuel.generateMasterKey(Pre-Master-Key)
s.send(ClientKeyExchange)
s.send(ChangeCiherSpec)
s.send(ClientFinished)
ServerFinished = s.recv()
#This will check if the server is ready to communicate securely.
if SSLManuel.checkServerFinshed(ServerFinished) == true:
#I can now use the SessionKey to encrypt data to and from the server
s.send(SSLManuel.encrypt(SessionKey, "GET / HTTP/1.0\n\n"))
response = s.recv()
print(SSLManuel.decrypt(SessionKey, response))
I hope the naming conventions used in this example can help you understand what I'm trying to accomplish. Most of my knowledge of SSL comes from This Article. I have tried to write my own but have failed and I can't seem to find any module that will allow me to do this.
