DTLSClientSocket

✓ import dtls

✗ from dtls import DTLSClientSocket

Simple DTLS client and server example using DTLSClientSocket and DTLSServerSocket.

import os from dtls import DTLSClientSocket, DTLSServerSocket # Client example client_socket = DTLSClientSocket() client_socket.connect(('localhost', 4433)) client_socket.send(b'Hello over DTLS') data = client_socket.recv(1024) print(data) client_socket.close() # Server example server_socket = DTLSServerSocket() server_socket.bind(('', 4433)) client, addr = server_socket.accept() data = client.recv(1024) print('Received:', data) client.send(b'Hello from server') client.close()

Debug

Known issues

gotchaThe library does not automatically handle DTLS retransmission timers. You must implement application-level timeouts or use threading to avoid blocking on recv() indefinitely if packets are lost.

fix

Wrap socket operations with timeout or use select module.

affects: <=1.3.0

deprecatedVersion 1.3.0 lacks support for DTLS 1.2; only DTLS 1.0 is supported. Upcoming versions may drop DTLS 1.0 completely.

fix

Be prepared to migrate to a library supporting DTLS 1.2 or later (e.g., pyOpenSSL with DTLS).

affects: <=1.3.0

gotchaThe library depends on pycrypto and pyopenssl. On some platforms, pycrypto may require a C compiler or additional system libraries (e.g., libffi-dev, libssl-dev).

fix

Install system dependencies: on Ubuntu/Debian run 'sudo apt-get install build-essential libssl-dev libffi-dev' before pip install.

affects: <=1.3.0

breakingIn version 1.3.0, the DTLSClientSocket and DTLSServerSocket classes were renamed from older names. Code using old class names will break.

fix

Use DTLSClientSocket and DTLSServerSocket instead of any previous names.

affects: 1.3.0
