用C编写的DES加密算法，通过运行。其中运用二叉树实现，只是例子，并不通用。为word格式。 -C prepared by DES encryption algorithm, by running. Which the realization of the use of binary tree, only examples, not generic. For the word format.

The program source code is in the word document. This is an encrption and decrption technique that uses the available tools for both the operations in CSharp. First a string is obtained from the user and stored in the specified file path. Then the co
