Description: 实现了三种古典密码学体制和DES体制及其分析。affine(仿射)读入文件11.txt中内容（小写字母，明文）加密并把内容写入12.txt，还可以解密生成文件13.txt。vigenere,hill体制类似。DES体制包括加密解密雪崩效应差分分析等内容。由于本人还是刚学习程序设计语言及密码学的在校本科生，水平很低，第一次上传只是为了试一下。可以考虑少给几点，呵呵。-achieve three classical cryptography system and DES system and its analysis. P14 (affine) read into the document 11. Txt contents (lowercase letters, expressly) encryption and written 12. txt, can also generate documents declassified 13. txt. Vigenere, hill similar system. DES encryption and decryption system, including avalanche effect Differential analysis of the contents. Because I still just learning programming language and Cryptography in undergraduate school, the low level Uploading is the first to try. Consider a smaller number of points-huh. Platform: |

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 Platform: |

Description: 实现了三种古典密码学体制与DES体制及其分析。affine(仿射)读入文件11.txt中内容（小写字母，明文）加密并把内容写入12.txt，还能解密生成文件13.txt。vigenere，hiill体体制类似。DES体制包含加密解密雪崩效应差分分析等内容。由于本人还是刚学习程序源码设计语言及密码学的在校本科生，水平非常低，第一次上传只是为了试一下。能考虑少给几点，呵呵。 可直接使用。
-Three classical cryptography system and DES system and its analysis. affine (affine) read the contents of a file 11.txt (lowercase letters, plaintext) is encrypted and write the contents 12.txt can decrypt the generated file 13.txt. vigenere, hiill body system is similar. DES system contains the encryption and decryption of the contents of the avalanche effect differential analysis. I still just learning the language of the program source code and cryptography in the undergraduate level is very low, the first upload just to try. Can consider less to a few points. Can be used directly. Platform: |
