python3-dtls 1.0.3 does not work with OpenSSL 1.1.1b

[mcfreis]

An "import dtls" fails with a Segmentation fault. This is due to a missing parameter in OPENSSL_init_ssl() in sslconnection.py.

Even after applying the previous patch I'm getting the following exception when running the example code from README.md:

Traceback (most recent call last):

During handling of the above exception, another exception occurred:

Well yes, I found that out myself a few days ago. The patch only makes the import dtls work but fails in all tests. unit.py, unit_warpper.py, echo_seq.py and simple_client.py all fail. With what version of OpenSSL do they work?

What is this testdtls.py? It is not included in the soruce.

@mcfreis testdtls.py is this:

import ssl
from socket import socket, AF_INET, SOCK_DGRAM
from dtls import do_patch
do_patch()
sock = ssl.wrap_socket(socket(AF_INET, SOCK_DGRAM))
sock.connect(('10.1.1.222', 5684))
sock.send('Hi there')
