[Cryptography-dev] what to import

[Robert Moskowitz]

Unfortunately, I go too much be copying examples.

I am not learning how to find the various components to load,

For example, I want to load an x509 cert:

https://cryptography.io/en/3.4.7/x509/reference.html#loading-certificates

with open(x509cert, "rb") as f:
     cert = f.read()
     cryptography.x509.load_pem_x509_certificate(cert)
     cert.serial_number

ImportError: cannot import name 'load_pem_x509_certificate' from 
'cryptography.hazmat.primitives' 
(/usr/lib64/python3.11/site-packages/cryptography/hazmat/primitives/__init__.py)

I can't find on the website where I am advised what to load.  So far, 
shotgunning it as not worked.  Nor should I really count on that approach.

So where is there advise for importing what from where?

thanks
