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: 还有一个缺陷就是在只知道密文 x 及公钥（n,e）的情况下，只要将 (x^e) mod n 所得余数 s 再不断地循环操作 s = s^e mod n，此运算不断地循环 e 次之后，很多情况下都可以循环出原文，只是计算量过余多一些罢了。不过有不少情况下，根本都无须循环 e 次，不过对于1024位的 n 级别来说，e 也是一个相当大的数值，所以循环密文的余数以解得原文是有些不现实。 以上内容仅供参考，如有不实，请予更正-there is a defect in only know that the secret and public key-x (n, e) the circumstances, as long as (x ^ e) mod n from the remaining s to continuously cycle operation s = s ^ e mod n, this constant cycle of Operational e occasion, the very many circumstances can be recycled from the original, but I calculated the volume more than just. There are, however, many instances, simply do not need e cycle times, but for 1024 the level n, e is a very large figure, so secret circle the remainder of the text was obtained in the original is a bit unrealistic. The above is for reference only, if not true, I corrected

Description: pass.words是弱口令字典，是一个纯文本文件，每行一个口令，可以向里面添加候选口令。
pass.c是进行口令检查的c语言原程序，有两个命令行参数
-w file: 可以使用该选项指定口令字典
-P:默认情况下对/etc/shadow中的用户检查弱口令，可以使用该选项指定检查的文件
编译gcc –o pass pass.c –l crypt
由于要使用加密函数，所以要使用加密库crypt，使用选项-l crypt
运行程序：pass –w ./pass.words –p /etc/shadow
-pass.words is a weak password dictionary, is a plain text file, one per line password, you can add to the inside candidate password. Password pass.c is the c language of the original inspection procedures, there are two command-line parameters-w file: You can use the password option specifies a dictionary-P: By default on/etc/shadow user to check the weak password, you can use the option to specify the documents to check the compiler gcc-o pass pass.c-l crypt function due to the use of encryption, so the use of encryption library crypt, use the option-l crypt running the program: pass-w./pass.words-- p/etc/shadow
