Description: S-DES的编程实现 S-DES的加密使用8位明文和10位密钥做为输入，产生8位的密文做为输出。加解密使用相同的密钥。要求:采用CBC模式对文本加解密 1.对话界面:选择加密或解密,输入密钥,在目录中选择明文或密文文件(内容为二进制,.txt文件,),提示加密或解密完成 2.输出:产生密文文本或明文文本 3.提供:说明文档,源码,可执行程序,通过加密实验,给出运行结果. 4.提交分析雪崩效应文档:相同密钥下明文改变任一位时密文的位差异情况 相同明文下密钥改变任一位时密文的位差异情况-S-DES Programming S-DES encryption using 8 and 10 expressly as a key input, have eight of dense text as output. Encryption and decryption using the same key. Requirements : CBC mode to a declassified version increases. Dialogue interface : Select encryption or decryption key input in the directory option expressly or dense text document (for binary content,. Txt file,), suggesting encryption or decryption completed 2. Output : produce dense text or text the text expressly 3. provide : documentation, source code, executables, through encryption experiment is running results. 4. analytical avalanche effect Document : Key under the same as an explicit change the text at the close of the differences in the same place where expressly as a key change at the potentiometer ciphertext the situation

Description: 之前，我在一个项目开发过程中，涉及到了TripleDes的算法，在实现过程中，我也参考了论坛现有的关于3DES的代码，发现大部分的代码在算法的实现上不够严谨，或者小有偏差，特别是对3DES的两种模式:ECB,CBC都罕有涉及。此版本提供的TripleDes可以实现3DES在两种模式下的2key/3key的加、解密。在速度优化和内存控制上都做了优化。-Before, I in a project development process, involving the TripleDES algorithms, in the realization of the process, I also made reference to a forum on the existing 3DES code and found that most of the code in the algorithm for the realization of loosely, or small deviations, especially for 3DES of two modes: ECB, CBC are rarely involved. This version provided by TripleDES 3DES can be achieved in two modes of 2key/3key increases, decryption. Optimized in terms of speed and memory control are optimized.
