Pure-python forbids using the cryptography package. Only python code and
the python stdlib are allowed. The fact that TLS uses AES at all means
it might be possible to trick the python ssl module to do arbitrary AES,
with some effort.
At the end of the day, the TLS protocol is also part of the ssl module's
API surface. It's not the API surface you'd usually interact with, but
nothing really stops you from doing so.

TLS does not use AES in a way that is consistent with what you would
get if you just used a typical AES library.

Python doesn't expose raw AES, etc. But it does expose a fairly
rich TLS library. Wondering if it would be possible to just
connect a TLS socket to a raw TCP socket and somehow write bytes
into TLS and get ciphertext out or write bytes into the raw TCP
socket and get plaintext out.
The point is to use AES for non-TLS protocols.

I'm not aware of any. Why would you want to do this? Most such
libraries I am aware of expose low-level primitives or are built
on libraries which do.

Has anyone done any work towards tricking a TLS library into

cryptographic primitives? We know of similar work with
regards to
javacard https://arxiv.org/abs/1810.01662 but not sure if it
can be
applied to TLS.
