关于非对称加密算法我就不过多介绍了，本文着重于python3对RSA算法的实现。 from Crypto.PublicKey import RSA import Crypto.Signature.PKCS1_v1_5 as sign_PKCS1_v1_5 #用于签名/验签 from Crypto.Cipher import PKCS1_v1_5 #用于加密 from Crypto import Random from Crypto import Hash x = RSA.generate(2048) # y = RSA.generate(2048, Random.new().read) #

PyCryptodome是python一个强大的加密算法库，可以实现常见的单向加密、对称加密、非对称加密和流加密算法。包含以下内容： 1.Base64编码 2.base64编码实现代码 3.单向加密算法 4.对称加密算法 5.非对称加密算法 6.流加密算法实现（以RC4为例）

官方学习手册，内含多个pdf文件，包括如何安装，到基本语法和高级的用法，讲的很全，是学习python3.8版本的很好资源包！
