本包内容包括信息系统安全工程课程中的密码学基础、公钥加密与RSA、分组密码与DES共3个章节的内容，原汁原味的老师课堂讲义~包你喜欢~~！...

Vigenere 体制 本程序使用dev c++开发实现，希望对大家有用.-Vigenere institutional procedures for the use of the dev c achieve development, we hope that the right useful.

AES加密软件，用于加密当前文本框中的内容。使用的是美国国家标准（也被ISO所采纳）最新加密算法AES。-AES encryption software, encryption for the current contents of the text box. The use of the American National Standards (also adopted by the ISO) the latest encryption algorithm AES.

c加密算法，比较实用的一程序，在别人那拷的.-c encryption algorithm, a more practical procedure, the copy of others.

大数运算库miracl。有了miracl这样的函数库，你可以直接调用函数，来实现你要的公钥密码学的某个功能。-Treasury computing large numbers miracl. With miracl this library, you can directly call the function, to realize that you ask for a public-key cryptography functions.

DES算法原理及实现,实现了3DES和DES的程序过程，支持8 16 24位密钥-DES algorithm and realize, realize the 3DES and DES procedures for the process to support the 81,624-bit keys

基于LSB的信息隐藏技术――MFC――编译已经通过运行正常-LSB-based Information Hiding- MFC- has been compiled by running the normal

uthash 是一个C语言的哈希表，支持各种结构类型的存储、添加、删除，这些操作都在固定的时间完成，跟哈希表本身的大小无关。键也可以是任何类型的数据。-is a C language uthash the hash table to support a variety of structural types of storage, add, delete, these operators are in a fixed time to complete, with the hash table size in itself has nothing to do. Keys can also be any type of data.
