idna-ssl

The `idna-ssl` library provides a patch for Python's standard `ssl.match_hostname` function to correctly support Unicode (IDNA) domains. It aims to offer backward compatibility for older Python versions (pre-3.7) where `ssl.match_hostname` had significant issues with internationalized domain names, and to address lingering IDNA2008 compliance problems even in later Python releases. The library's current version is 1.1.0, released in July 2018. The project's GitHub repository has been archived and is read-only since October 2020, indicating it is no longer actively maintained.
