用C写的DES加密的一个算法。是很不错的。-Using C written by a DES encryption algorithm. Is very good.

StreamSec Security Library含有多种算法的控件-StreamSec Security Library contains a variety of control algorithms

A simple cpp program, that receives a file, does a bit-wise "not" for every character, and adds "not" to the extension. Repeated running does the same and removes the "not" from extension. This a "pseudo-encryption", but very useful to avoid automated filtering software. This way it is possible to send "exe" files (or anything else) without the emails being blocked... First - send the source code, have your (enlightened) recipient compile it, then send the "notted" file. The code is not very efficient though, I only had 30 minutes to invest... :)-A simple cpp program, that receives a file, does a bit-wise "not" for every character, and adds "not" to the extension.

该程序是使用恺撒密码和transposotion密码。也许这个计划太简单了，但总比没有强。：V

是用的美国标准的DES加密算法用C++编写的可以完成以内的字符垢加密-the United States is using the DES encryption standard algorithm with C prepared to be completed within the characters scale encryption

一种国际上通用的加密算法―DES算法的原理-a common encryption algorithms-DES algorithm Principle

PGP 是一种混合密码系统。当用户使用PGP 来对纯文字加密的时候， PGP 首先会压缩这 段纯文字。数据压缩能够节省调制解调器传输时间以及磁盘类空间，还有更重要的、强化密码法的 保密程度。-PGP is a hybrid cryptosystem. When the user to use PGP to encrypt the text, PGP will first this text compression. Data compression can save time and modem transmission disk space, and more importantly, to strengthen the password confidentiality law.

用于GSM加密的A5算法实现- Uses in GSM the encryption A5 algorithm to realize

DES( Data Encryption Standard)算法，于1977年得到美国政府的正式许可，是一种用56位密钥来加密64位数据的方法。DES算法以被应用于许多需要安全加密的场合。（如：UNIX的密码算法就是以DES算法为基础的）。-DES (Data Encryption Standard) algorithm, in 1977 the United States government"s official permission, is a key 56 to 64-bit data encryption methods. DES algorithm to be applied to many needs security encryption occasions. (Eg : UNIX password algorithm is to DES algorithm-based).

md5例程 主要可以通过程序了解md5如何加密，在编程是可以直接借用。-md5 routines mainly through the process to understand how md5 encryption, in the programming can be borrowed directly.
