This all looks good, however I still struggle with the public key. Using cryptography only this time:

public_key = cert.public_key() print public_key <cryptography.hazmat.backends.openssl.ec._EllipticCurvePublicKey object at 0x10fc6dfd0>

So it has the public key, and correctly knows its elliptic curve.

If I now want to break out all of the components/attributes of the public key object then how should I do it? What would be the best way? I guess I want SubjectPublicKeyInfo as well as the actual public key?

The details I am hoping to find include:

Subject Public Key Info:
