1、python3的PyCryptodome库用于密码学，属于对PyCrypto库的扩展

Linux上安装：

pip install pycryptodome

Windows上安装：

pip install pycryptodomex

from Cryptodome.PublicKey import  RSA
import Cryptodome.Signature.PKCS1_v1_5 as sign_PKCS1_v1_5  # 用于签名/验签
from Cryptodome.Cipher import PKCS1_v1_5  # 用于加密
from Cryptodome import Random
from Cryptodome import Hash
