Generating public key with EC in Python

Question

I'm creating JWT parser and now I need to create public key. I made it in Kotlin. But now I have to create same parser in Python. But I got stuck in creating X.509 certificate in python. I tried with cryptography library but with no success. Code in Kotlin. Thanks for responses.

val factory = KeyFactory.getInstance("EC")
val publicSpec = X509EncodedKeySpec(Base64.getMimeDecoder().decode(key))
return factory.generatePublic(publicSpec)

You should probably combine this tutorial about generating a self-signed certificate and replacing the private key generation with this material.

Key generation example with SECP384R1:

from cryptography.hazmat.backends import default_backend
from cryptography.hazmat.primitives import hashes
from cryptography.hazmat.primitives.asymmetric import ec
key = ec.generate_private_key(
     ec.SECP384R1(), default_backend()
)

I tried this library but with no success. – Patrik Dendis Sep 05 '19 at 14:31
@PatrikDendis Well, show your code so we can help – Lou_is Sep 06 '19 at 05:43
Thanks @Lou_is but I gave it up and I used generated public key from Kotlin and then just paste to Python. – Patrik Dendis Sep 06 '19 at 07:56
