In the simplest case, this means *host name verification*. However, ``service_identity`` implements `RFC 6125`_ fully and plans to add other relevant RFCs too. ``service_identity``\ ’s documentation lives at `Read the Docs `_, the code on `GitHub `_. .. _Twisted: https://twistedmatrix.com/ .. _pyOpenSSL: https://pypi.org/project/pyOpenSSL/ .. _MITM: https://en.wikipedia.org/wiki/Man-in-the-middle_attack .. _RFC 6125: https://www.rfc-editor.org/info/rfc6125 .. _PyCA cryptography: https://cryptography.io/
