In CPython 3.10 there were private APIs SSLObject.get_verified_chain() and _ssl.Certificate.public_bytes(_ssl.ENCODING_DER) methods added.

Ref: python/cpython#25467

import hashlib
import _ssl
fingerprints = [hashlib.sha256(cert.public_bytes(_ssl.ENCODING_DER)).hexdigest() for cert in sock._sslobj.get_verified_chain()]
