我根据comp430s改写的DLL源码，可在多线程下使用。还带有DES加密算法函数 -DLL source which is overwirted by comp430s, can be used in multi-thread.Attached by DES encryption Algorithm

slrc632程序..网上绝对找不到.对RC632读TYPEB完整的程序包-procedures .. slrc632 absolutely can not find online. TYPEB of Reading RC632 complete package

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

数字水印，用MATLAB制作的，还有一些叙述情况-Digital Watermarking using MATLAB produced, and some described the situation

流密码算法,可用于文件加密和实时通信 ,设计者是著名的密码学家Rivest.该算法效率远高于一般分组密码,并且很适合用于随机数生成-Stream cipher algorithm, can be used for file encryption and real-time communication, the designer is well-known cryptographer Rivest. The algorithm efficiency is much higher than the general block cipher, and is suitable for random number generator
