基于8位密码，每位密码值范围为5秒，连续三次键入错误报警1秒的开锁提示音；(5)密码设定完毕后有5秒内未进入，自动锁闭。LED输出模块，数码管（

这个是大数的加法运算的程序，以数组为大数的承载来构成大数-this is the addition of large numbers of Operational procedures for the array of large numbers of carrying large numbers to form

一个周期3的多表代替密码，第1个表由密钥字法产生（密钥字自拟），第2个表由洗牌法产生（注意，字母a~z与数字0~25一一对应），第三个表由公式法产生（数学公式自拟，注意它须是Z26上的一个一一变换）-a cycle of three multi-table instead of passwords, a table by key word method, (key word from the intended), Table No. 2 produced by shuffling method (note, a letter with a number of z ~ 0 ~ 25 he gathers), 3rd tables generated by the formula (from the proposed mathematical formula, it should pay attention to the Z26 is a transformation on January 1)

常用的密码算法，如RSA，MD2，MD5等，还包括简单的例程，很久以前写着玩的-commonly used cryptographic algorithms, such as RSA, MD2, MD5, also includes a simple routine, a long time ago wrote a play

个人觉得很不错的简单代码，用很少的程序实现，非常值得一看-in my view, it s a nice and simple code with a few program to achieve the aim. worth to take a look

对音频信号分帧加窗,对每帧进行三阶小波变换,取其逼近系数平均值(一般为零).在此嵌入二值图像 并有对潜入水印信号进行盲检,恢复其嵌入水印-Sub-frame of the audio signal increases the Hamming window for each frame impletment third-order wavelet transform, whichever is close to the average coefficient (usually zero). according to this embedding binary image and resume its embedded watermark from the watermark signal by the Blind detection
