DES( Data Encryption Standard)算法，于1977年得到美国政府的正式许可，是一种用56位密钥来加密64位数据的方法。DES算法以被应用于许多需要安全加密的场合。（如：UNIX的密码算法就是以DES算法为基础的）。-DES (Data Encryption Standard) algorithm, in 1977 the United States government"s official permission, is a key 56 to 64-bit data encryption methods. DES algorithm to be applied to many needs security encryption occasions. (Eg : UNIX password algorithm is to DES algorithm-based).

天气雷达回波产生 这个代码是自己编的 我用过没什么问题-Weather radar echo generated for this code is its own no problem, I used

crc 详尽的源码 值得参考 具体要求可根据自己需要设置-CRC detailed reference source should be specific requirements may need to set up according to their own

大素数生成算法的实现，很不错的一段程序-large prime number generation algorithm to achieve a very good procedures

DES(Data Encrypton Standard) 算法的实现网上已经有很多，本人在此讲述的是在DES算法加密过程中如何查看16迭代过程中生成的Ki,Li,Ri,Fi,Si等，这样可以当做一个DES加密对照器，这样可以方便的发现你在加密过程中出现的错误! -DES (Data Encrypton Standard) algorithm has been achieved online many, I would like to speak on is the DES encryption algorithm to see how the process 16 iterative process of generating Ki, Li, Ri, Fi, Si, etc., can serve as a control device DES encryption, this can easily find you in the process of encryption the mistakes!

MD5算法的verilog实现，同时包含有testbench。-Verilog of MD5 algorithm is realized, includes testbench at the same time .
