如何从RSA公钥中提取N和E

python实现

#!/usr/bin/env python3
from Crypto.PublicKey import RSA

path = '<key file path here>'
with open(path) as f:
    key = RSA.import_key(f.read())
    print('e = %d' % key.e)
    print('n = %d' % key.n)

python RSA Module ：RSA — PyCryptodome 3.17.0 documentation

openssl命令行实现

openssl rsa -inform PEM -in Key0_pub.pem -pubin -text -out Key1_pub.txt
