这个是关于des原吗的文件 是64位的 下次上传个32位的 请大家谅解...

windows的加密api源码-windows encryption api source code

由于BT老师的要求，非要将64位DES算法改编成16位的DES算法，小生在这里献丑了。-as teachers, add to the 64-bit DES algorithm adapted into 16 of the DES algorithm, Niche in a shortcoming here.

为一个字节或字符数组或串计算md5值，内部只创建一个数组，节省分配时间，节省内存 完全是static方法，线程安全 注意对返回值的处理，见注释-for a byte array or character string or md5 value calculation, only to create an internal array, saving time allocated to save memory is completely static method, thread-safe attention to the return value, see note

md5的源代码，我下了源代码不过不知道怎么使用哦，请各位大哥多多指教呀！-md5 source code, I had the source code but do not know how to use Oh, please enlighten me a lot of big brother!

AES Rijndael fast security system to encrypt and deycrypt information

RSA的实现，可以根据文章来实现RSA算法-RSA realized, according to the article to achieve RSA 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。
