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: 根据设计要求：1）具有文件加密和解密功能；2）具有加解密速度统计功能；3）采用密文反馈链接和密文挪用短块处理技术。我们可以知道，程序要有加密模块、解密模块、子密钥生成模块，这三个模块构成DES算法。DES算法再构成3DES，这很简单，只要加个密钥便可实现。3DES还必须工作在密文反馈连接模式下和使用密文短块挪用技术。至于速度统计功能就很好实现，用文件长度除以处理时间便是加解密速度。-based on the design requirements : 1) with file encryption and decryption function; 2) the speed with the encryption and decryption functions of statistics; 3) Use of dense text links and feedback secret misappropriation short pieces of text processing technology. We know that procedures have encryption module, decryption modules for key generating modules, which constitute three modules DES algorithm. DES algorithm constitute 3DES, this is very simple, as long as add key can be reached. 3DES must also work in close link text feedback mode and the use of short text block secret misappropriation of technology. As for the speed of statistical functions properly achieved, divided by the length of documents with the processing time is the speed encryption and decryption.

Description: DES工作的基本原理是，其入口参数有三个:key、data、mode。 key为加密解密使用的密钥，data为加密解密的数据，mode为其工作模式。当模式为加密模式时，明文按照64位进行分组，形成明文组，key用于对数据加密，当模式为解密模式时，key用于对数据解密。实际运用中，密钥只用到了64位中的56位，这样才具有高的安全性。
-The basic principle of DES is that its entrance there are three parameters: key, data, mode. key used for encryption and decryption keys, data encryption and decryption for the data, mode of its work. When the model for the encryption mode, expressly in accordance with the grouping 64 to form a specific group, key for data encryption, when the model mode for decryption, key for decryption of data. Practical application, the key has been used only 64 of 56, so that with high security.
