椭圆曲线加密算法-elliptic curve cryptosystem

数据加密算法，很好的东东，下了试试看就知道了。-Data encryption algorithm, a very good Dongdong, a try to know.

实现数据库安全编程,写了一个MD5的加密库-Database Security Programming realize, write a MD5 encryption library

软件模拟CRC冗余校验，可以对任意长度的发送序列求16位校验和，并且可以对接收序列进行检查。有详细的中文注释，和模拟函数-simulation software CRC Redundancy Check, for any length of this sequence for 16 checksum, and to be able to receive sequence for the examination. The Chinese have detailed notes and simulation function

base64解码 -base64 decoding base64 decoding

one of example about hardware design language

C++ implementaion for RSA together with the Wiener attack. It uses NTL library for big numbers

base64码转换程序,不够完善-base64 code conversion, not perfect

用Visual c++实现数字图像迭代混沌加密-Using Visual c++ Realize digital image iterative chaotic encryption

按照分组密码运行的CBC方式，将其中的DES算法置换为S-DES，分组长度为8BIT，初始矢量V1分别设置为00H,FFH,及任意8BIT无符号整数，实现该加密/解密模型-running CBC, which will be the replacement for the DES algorithm S-DES, a length of 8BIT initial vector V1 were set to 00H, FFH, and the arbitrary 8BIT unsigned integers, the achievement of this encryption/decryption model
