代码环境，python3.5.2

RSA加密的过程是：使用公钥加密，私钥解密

RSA签名的过程是：使用私钥签名，公钥验证

所以核心代码就是，生成公钥私钥，使用公钥私钥分别进行加密解密。

在实际编码的时候，使用python自带的RSA库，需要特别处理编码问题，因为默认的加密解密函数是接收bytes类型的数据。

加密的核心代码如下：

# -*- coding: utf-8 -*-
import rsa
import base64
(public_key, private_key) = rsa.newkeys(1024)
msg = "M2Crypto python关于RSA的库还是蛮多的，当然也可以直接用openSSLｑｗｅａｓａｓｄ１２３"
msg = msg.encode(encoding="utf-8")
encrypt_msg = rsa.encrypt(msg, public_key)decrypt_msg = rsa.decrypt(encrypt_msg, private_key)
print("公钥:")
print(public_key.save_pkcs1().decode('utf8'))
print("\n私钥:")
print(private_key.save_pkcs1().decode('utf8'))
print("\n原始文本:")
print(msg.decode('utf8'))
print("\n加密后的文本:")
print(base64.encodebytes( encrypt_msg).decode('utf8'))
print("\n解密后的文本:")
print(decrypt_msg.decode('utf8'))

输出结果如下：

结合tkinter的代码如下，使用tkinter是因为绘制界面很简单：

# -*- coding:utf-8 -*-
from tkinter import *
import rsa
import base64def GenerateKey():(public_key, private_key) = rsa.newkeys(1024)print("\n生成公钥："+public_key.save_pkcs1().decode('utf8'))print("\n生成私钥："+private_key.save_pkcs1().decode('utf8'))publicKeyText.delete(0.0, END)publicKeyText.insert(END, public_key.save_pkcs1().decode('utf8'))privateKeyText.delete(0.0, END)privateKeyText.insert(END, private_key.save_pkcs1().decode('utf8'))def EncryptionByPublickey():           #用公钥加密public_key_str = publicKeyText.get("0.0", "end").encode(encoding="utf-8")public_key = rsa.PublicKey.load_pkcs1(public_key_str)entry_str = entryText.get("0.0", "end").encode(encoding="utf-8")encrypt_msg = rsa.encrypt(entry_str, public_key)print("公钥加密后的文本为：\n"+base64.encodebytes(encrypt_msg).decode('utf8'))outputText.delete(0.0, END)outputText.insert(END, base64.encodebytes(encrypt_msg).decode('utf8'))def EncryptionByPrivatekey(): private_key_str = privateKeyText.get("0.0", "end").encode(encoding="utf-8")private_key = rsa.PrivateKey.load_pkcs1(private_key_str)entry_str = entryText.get("0.0", "end").encode(encoding="utf-8")encrypt_msg = rsa.encrypt(entry_str, private_key)print("私钥加密后的文本为：\n"+base64.encodebytes(encrypt_msg).decode('utf8'))outputText.delete(0.0, END)outputText.insert(END, base64.encodebytes(encrypt_msg).decode('utf8'))  def DeryptionByPublickey(): public_key_str = privateKeyText.get("0.0", "end").encode(encoding="utf-8")public_key = rsa.PrivateKey.load_pkcs1(public_key_str)entry_str = entryText.get("0.0", "end").encode(encoding="utf-8")encrypt_msg = base64.decodebytes( entry_str)outputText.delete(0.0, END)try:decrypt_msg = rsa.decrypt(encrypt_msg, public_key)print("公钥解密后的文本为：\n"+decrypt_msg.decode('utf8'))outputText.insert(END,decrypt_msg.decode('utf8'))except:decrypt_msg = "公钥解密失败"print(decrypt_msg)outputText.insert(END,decrypt_msg)
