scu_des's Introduction

DES不同模式下python实现

  1. 文件说明

    • ctf.py存放算法常量如ip置换矩阵等
    • des.py des算法部件模块
    • readandwrite.py 控制密钥,明文,密文,iv文件读写
    • mian.py主体文件
    • recording.txt 测试结果保存
    • des_key.txt 存放密钥
    • des_iv.txt 存放iv
    • des_plain.txt 存放明文
    • des_Cipher.txt 存放show()结果

    2.功能实现:

    1. 对简单明文在ECB,CBC,CFB,OFB进行DES加密;
    2. 生成随机固定大小文件并对文件内容进行加密;
    3. 测试不同模式50MB的文件反复加解密50次所用时间;

    3.代码结构展示:

    image-20200405123303875

    4.引用说明:

    1.生成随机固定大小文件摘自网络

    2.ctf静态数据文件数据摘自网络
