Library Updates for 2024

[frobnitzem]

This project pypi:Dtls seems to have been re-released and updated as pypi:python3-dtls, which exists at github:mcfreis/pydtls.

Unfortunately, github:mcfreis/pydtls is a fork, so can't handle its own issues. It also does not appear to have all its tests modernized to python3.

Most urgently, loading github:mcfreis/pydtls
shows that the openssl wrapper has been affected by bitrot between libssl.so.1.1 and libssl.so.3:

dtls% python3
Python 3.10.12 (main, Sep 11 2024, 15:47:36) [GCC 11.4.0] on linux

>>> import dtls

AttributeError: /lib/x86_64-linux-gnu/libssl.so.3: undefined symbol: SSL_get_peer_certificate
>>> exit()

Fixing this could ideally be done by replacing dtls/x509 and dtls/openssl by community-supported wrappers from py/cryptography.

Anyone willing to support / take on this task?

You are right - since Python 2 is deprecated, I no longer maintain this project. However, I do sometimes accept contracts for work such as this. If you're interested in that, let me know.
