如何在python中从RSA公钥中提取N和E？

pip install cryptography

from cryptography.hazmat.primitives import serialization
from cryptography.hazmat.primitives.asymmetric import rsa

# 从文件中加载公钥
with open('public_key.pem', 'rb') as key_file:
    public_key = serialization.load_pem_public_key(
        key_file.read(),
        backend=default_backend()
    )

# 提取N和E
n = public_key.public_numbers().n
e = public_key.public_numbers().e

print("N:", n)
print("E:", e)
