Solution to File Encryption Based on Multiple Mode Encryption Algorithm
一种基于多模式加密算法的文件保护方案*

This paper presented a solution to the file encryption which use symmetric encryption methods such as DES,IDEA,AES and hash algorithms such as MD5,SHA-1,SHA-256.Many encryptions can be used to encrypt a file in the solution.Files encrypted by this solution are more secure than those traditional ones.An implement method based this solution was given,its practicability is proofed by experiments.At last this paper discussed some strongpoints and shortages about this solution.
