des的变形算法，很有用的

the code can be used to encrypt your folder.

文本加密，利用异或操作对指定文件进行加密，加密密码由用户输入-Text encryption, the use of XOR operations on the specified file is encrypted, encryption, password from user input

其实网上这方面的代码已经不少了,但是大多都如出一辙,主要是给出的代码不但不好理解(主要是为了处理大文件,支持分块,这样就会屑弱初学者对算法的理解),该源代码在引入必要头文件后可以在VC6.0下顺利通过编译-fact that the Internet has been a lot of code, but most of all the same, given the code is not only poor understanding (mainly to handle large files, support block, which would litter beginners weak understanding of the algorithm), the source code necessary to the introduction of the first document in VC6 .0 smoothly through the compiler

This program encodes and decodes a character using the Vigenere Square method

密码算法中的单向散列函数之SHA算法的C代码-password algorithm for one-way hash algorithm SHA Function of C code

尹学渊版的DES第二版，注释写得非常清楚，并且执行效率不错，代码质量相比第一版有很大的改进，尹学渊保留所有权利，转载自：http://www.cnblogs.com/erwin/-The second edition of YinXueyuan s DES code,the Notes is very clear, and good performance, code quality compared to a significant improvement over the first edition, All rights reserved.YinXueyuan, reprinted from: http://www.cnblogs.com/ erwin /

一个用3DES加密文件的小测试程序！-a document using 3DES encryption small test program!

很多加密算法的C实现-lot of the encryption algorithm to achieve C

des加密算法的c程序实现，能够加密8位明文，经测试通过编译。-des encryption algorithm c Program to express encryption eight, the test compiler.

包含的.m 文件那土窖使用 RSA Algorihtme 所以享受它只笑着现在这由创建的 hahahahahhahahahhah"肖恩 · 戈麦斯"大家伙从我不知道请结束 100 字符:)
