一. 安装RSA模块
参考http://changfengmingzhi.blog.163.com/blog/static/167105288201331594158559/
1. 下载ez_setup.py（http://peak.telecommunity.com/dist/ez_setup.py)
2. 用python解释执行它 （如使用IDLE打开该py文件，按F5解释执行）
3. 安装完成后，会在scripts文件夹下生成几个exe可执行文件。（如： D:Python27Scripts目录下）
4.可以把之前下载的文件rsa-3.1.1-py2.7.egg拷贝到D:Python27Scripts目录下, 然后在cmd中切换到D:Python27Scripts目录下，执行egg文件：easy_install.exe rsa-3.1.1-py2.7.egg
二. 用Python进行RSA加密实例
实例源码如下：
import os import sys import math def GetDataFromFile(filename): f = open(filename) n = int(f.read(),16) print('*'*77) print(filename) print(hex(n)) print('*'*77) return (n) def my_RSA_encrypt(src, d, n): x = pow(src, d, n) print('*'*77) print("Encrypted Data is:") print(hex(x)) print('*'*77) return x def my_RSA_decrypt(src, e, n): y = pow(src, e, n) print('*'*77) print("Decrypted Data is:") print(hex(y)) print('*'*77) return y path = os.getcwd() #==================================== fname = path "\Firm_N.txt" plaintData = GetDataFromFile(fname) fname = path "\Manuf_private_d.txt" d = GetDataFromFile(fname) fname = path "\Manuf_N.txt" n = GetDataFromFile(fname) encryptedData = my_RSA_encrypt(plaintData, d, n) #==================================== fname = path "\Firm_public_e.txt" plaintData = GetDataFromFile(fname) fname = path "\Manuf_private_d.txt" d = GetDataFromFile(fname) fname = path "\Manuf_N.txt" n = GetDataFromFile(fname) encryptedData = my_RSA_encrypt(plaintData, d, n) #====================================
