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。-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.

硬件求解平方根源代码加密 (硬件求解平方根的，将license添加到原有的MaxplusII或QuartusII的license中就可以直接使用，但源代码加密。altera提供 )-solving square root of the hardware encryption code (square root of the hardware solution will be added to the original license MaxplusII or Quartus II of the license which can be directly used, but the source code encryption.

What Does the code DO? Sometimes we may desire to hide our file contents from others.One of the possible way is encrypting these files.Here a simple encryption technique is used(In VB - The same technique can be implemented in "c" also.) Program flow Explained * Open the File to be encrypted for Binary Access Read(Say Source File) * Open a temparory file where encrypted data is stored for Binary Access Write(Say Destination File) * Loop through the Source File Byte by Byte * For each byte read from the file, Complement the data. (Using Not operator (in C we have to use "~" operator) * Write Complemented Data to Destination File * Delete the Source File * Rename Destination file as Source File(Now Encryption is over) -What Does the code DO? Sometimes we may desire to hide our file contents from others.One of the possible way is encrypting these files.Here a simple encryption technique is used (In VB- The same technique can be implemented in

Internet ssl的加密软件-Internet ssl encryption software

使用7Z开源代码，实现的自定义的压缩解压程序，可以和自己的程序组合，提高效率

这是很好的源代码，对于很多的童鞋来说是非常好的资料，而且程序简单易懂。本程序是在VISUAL C++6.0运行，不过在其他版本的软件上应该也可以运行。
