一种口令加密工具的设计与实现

在利用对称加密算法时，密钥管理是安全系统考虑的主要问题。现有保存密钥的方法大都需要借助物理介质来保存，给用户带来了不便。为了解决这个问题，该文提出了一种基于口令的加密方案，能很好的解决密钥保护问题．最后在．Net平台下编程实现了一个基于口令的加密工具：实现创建自提取的可执行加密文件，使得基于口令的加解密可以独立的进行。

Design and Implementation of the Password Encryption Tool

When using symmetric encryption algorithms,key management is the main issue to security system.Existing ways to save the key almost need to through physical media,bringing users the inconvenience.In order to solve the problem,this paper proposed a pass-word-based encryption scheme;it can be a good solution to the key protection issues.Finally,coding the program to implement a pass-word-based encryption tool on the.Net platform;On this basis,to achieve and create a self-extracting executable encrypted file,s...
