This will probably be just another unsolved thread but i'll fill in some info anyway.
I can't get my SSL wrapping together not even for a second. Any ideas to what i'm doing wrong with my wrap_socket() and do_handshake()?
The key files appear to be 100% perfect, and i've tried with AND without the .recv() before the handshake. That just generates these depending on where i put the recv():
SSL3_GET_CLIENT_HELLO:wrong version number
SSL3_GET_RECORD:wrong version number
class Server():
def __init__(self, listen = '', port = 8080, ssl = False):
self.sock = socket.socket()
self.sock.bind((listen, port))
self.sock.listen(5)
def accept(self):
newsocket, fromaddr = self.sock.accept()
newsocket.recv(32)
newsocket.setblocking(0)
sslsock = ssl.wrap_socket(newsocket,
server_side=True,
certfile="./kernel/sock/server.crt",
keyfile="./kernel/sock/server.key",
cert_reqs=ssl.CERT_NONE,
ssl_version=ssl.PROTOCOL_TLSv1,
do_handshake_on_connect=False,
suppress_ragged_eofs=True)
sslsock.do_handshake()
return sslsock, fromaddr
For the record, if it's not obvious or i'm wrong, it's the handshake that fails :)
I modified the code a bit, trying SSLv3 and also change the position of the wrapping a bit:
import socket, ssl, time, select
class Server():
def __init__(self, listen = '', port = 443, ssl = False):
self.sock = socket.socket()
self.sock.bind((listen, port))
self.sock.listen(5)
def accept(self):
self.sock = ssl.wrap_socket(self.sock,
server_side=True,
certfile="./kernel/sock/server.crt",
keyfile="./kernel/sock/server.key",
cert_reqs=ssl.CERT_NONE,
ssl_version=ssl.PROTOCOL_SSLv3,
do_handshake_on_connect=False,
suppress_ragged_eofs=True)
newsocket, fromaddr = self.sock.accept()
print [newsocket.recv(32)]
newsocket.setblocking(False)
newsocket.do_handshake()
return newsocket, fromaddr
s = Server()
ns, na = s.accept()
print ns.recv(1024)
Now i get with the newsocket.recv(32):
ssl.SSLError: [Errno 1] _ssl.c:1331: error:140940E5:SSL routines:SSL3_READ_BYTES:ssl handshake failure
and without:
ssl.SSLError: [Errno 2] _ssl.c:490: The operation did not complete (read)
Also: i refuse to use Twisted
Scaling things down:
import socket, ssl, time, select
from OpenSSL import SSL
class Server():
def __init__(self, listen = '', port = 443, ssl = False):
ctx = SSL.Context(SSL.SSLv23_METHOD)
ctx.use_privatekey_file("server.pem")
ctx.use_certificate_file("server.pem")
self.sock = SSL.Connection(ctx, socket.socket())
self.sock.bind((listen, port))
self.sock.listen(5)
def accept(self):
newsocket, fromaddr = self.sock.accept()
return newsocket, fromaddr
s = Server()
ns, na = s.accept()
print ns.recv(1024)
This works just as good as the "native" ssl library. However now i get this error:
OpenSSL.SSL.Error: [('SSL routines', 'SSL23_READ', 'ssl handshake failure')]
This is where i'm at now:
import socket, ssl, time #, select
class Server():
def __init__(self, listen = '', port = 443, ssl = False):
self.sock = socket.socket()
self.sock.bind((listen, port))
self.sock.listen(5)
def accept(self):
self.ssl_sock = None
while not self.ssl_sock:
self.ssl_sock = ssl.wrap_socket(self.sock,
server_side=True,
certfile=r"C:\moo.pem",
keyfile=r"C:\moo.key",
cert_reqs=ssl.CERT_NONE,
ssl_version=ssl.PROTOCOL_TLSv1)
newsocket, fromaddr = self.ssl_sock.accept()
print([newsocket.recv()])
return newsocket, fromaddr
s = Server()
ns, na = s.accept()
print(ns.recv(1024))
This works "prefectly" in Firefox, but NOT in Google Chrome. Why? what's the difference? -.-
I don't know Python at all to tell you if you have a problem in your code.
The error though is clear. The client supports SSLv3
and your server only TLSv1
.
So you should enable support for SSLv3
or upgrade your client.
This line seems to be the problem:ssl_version=ssl.PROTOCOL_TLSv1
. Perhaps you can also add SSLv3
here?
Update:
I see that you have problem between browsers. See if SSLv3
is enabled in Crome.
In IE for example this is under Internet Options
-> Advanced Tab
.
Something similar should be in Chrome. Disable SSv3
and enable TLSv1
instead
