[spam][crazy] Adding Cert Pinning to E-X

[Undiscussed Horrific Abuse, One Victim of Many]

so I websearched around ssl python connection fingerprint or somesuch
and got to https://www.solrac.nl/retrieve-thumbprint-ssltls-python/
which has example code showing using the peercert, but they pass True
to a function to get it, which seems to work:

(Pdb) ctx = session.transport._asyncio_transport.get_extra_info('ssl_object')
(Pdb) p ctx.getpeercert()
{}
(Pdb) p ctx.getpeercert(True)
