Rijndael (AES) original small encryption algorithm implementation

RSA算法的C++实现。公钥加密算法中使用最广的是RSA。RSA算法研制的最初理念与目标是努力使互联网安全可靠，旨在解决DES算法秘密密钥的利用公开信道传输分发的难题。-RSA algorithm is the C++ implementation. Public key encryption algorithm is the most widely used is RSA. RSA algorithm is developed by the original idea and objective is to make the Internet safe and reliable, aimed at resolving the DES algorithm is a secret key transmitted using the open channel distribution problems.

MD5简单版的杂凑函数；使用C++语言编写-MD5 Hash Function

密码安全方面的PGP资料,很有用的!是学习密码学的好东西@-PGP password security information, very useful! Is a good thing to learn cryptography @

RSA密聊，用于网络上实现公锁和私锁的算法。-RSA secret chat for the network to achieve public and private lock lock algorithms.

DES算法，在VC++环境下调试，对成密码算法-DES algorithm, in VC++ Debugging environment, and into a cryptographic algorithm

本次实现采用流水线结构，分析子密钥与原始密钥的直接关系，利用组合逻辑同时产生16个子密钥，总体上既兼顾了效率，又不占用太多资源，经仿真测试，完全通过。

Converst a bit array into a single byte and vice versa

LZW编码是围绕称为词典的转换表来完成的。这张转换表用来存放称为前缀(Prefix)的字符序列，并且为每个表项分配一个码字(Code word)，或者叫做序号。这张转换表实际上是把8位ASCII字符集进行扩充，增加的符号用来表示在文本或图像中出现的可变长度ASCII字符串。扩充后的代码可用9位、10位、11位、12位甚至更多的位来表示。

这是一关于DES加密算法的C/C++实现范例-This is the one on the DES encryption algorithm C/C++ Realize Example

通过对OpenSSL对称密码算法函数的调用，实现常用的对称加密。这个工具主要的功能已经实现，而且还可以对大文件进行加密，可能效率上还需进一步完善，因为对大文件加密时，太差劲的电脑会感觉有点卡！另外，它还可以对电影加密，不妨一试。-Symmetric cryptographic algorithm through OpenSSL function calls to achieve common symmetric encryption. The main function of this tool has been achieved, but also can encrypt large files, you may need to further improve efficiency, because the large file encryption, too bad the computer will be felt Dianka! In addition, it can encrypt the film, worth a try.
