ISGCSSecure增强Client/Server系统安全的控件。(源代码，需注册）价格：$799。工作在：CB1 CB3 D3 D4 D5。作者：Infinity Software Group--Control which uses ISGCSSecure to enhanced Client/Server system security .(with source codes,needing register) price:$799.works in:CB1 CB3 D3 D4 D5.author:Infinity Software Group

算法参考于《密码编码学及网络安全》上关于RSA加密算法的定义。相关程序在Visual C++ 6.0上能正确运行（估计在其他C语言编程环境下也能运行吧），程序里面详细写上了注解，希望能够给你带来帮助。

密码生成器，很好用-password generator, a good use

DES算法全称为Data Encryption Standard,即数据加密算法,DES算法把64位的明文输入块变为64位的密文输出块,它所使用的密钥也是64位。RSA的安全性依赖于大数分解。公钥和私钥都是两个大素数（ 大于 100个十进制位）的函数。本程序为适合初学者的rsa算法java源码及des源码，开发环境eclipse3.4-DES algorithm called the Data Encryption Standard, that is, data encryption algorithm, DES algorithm to express the 64-bit input block into a 64-bit output ciphertext block, it is also used 64-bit key. RSA" s security depends on the decomposition of large numbers. Public key and private key are two large prime numbers (more than 100 decimal places) of the function. This procedure is suitable for beginners of rsa algorithm java source and des-source, development environment eclipse3.4

RC2算法源代码-RC2 algorithm source code

The Advanced Encryption Standard (AES) specifies a FIPS- approved cryptographic algorithm that can be used to protect electronic data.  The AES-128 pipelined cipher module uses AES algorithm which is a symmetric block cipher to encrypt (encipher) information. This module is optimized for speed as it pipeline hardware to perform repeated sequence called round
