Encryption File Used File

当今社会,对网络中传输的数据进行加密已变得越来越重要,特别是一些机密文件在网络上传输必须采取加密措施。加密可有效地防止有用或私有化信息在网络上被拦截和窃取。本文通过VS.NET2005下创建一个Visual C# windows应用程序,来实现利用文件加密文件。利用该程序可以实现文本文件、Office文件、RAR压缩文件、多媒体文件等各种类型文件的加密和解密,其密钥同样为各种类型的文件,相比字符加密方式,该方法更加安全高效。

Today＇s society, the network transmission of data encryption has become increasingly important; especially in some confidential documents on the network transmission encryption measures must be taken. Encryption can be effective in preventing the privatization or useful information on the Internet is blocked and the theft. Through the creation of a VS.NET 2005 under Visual C # windows application to achieve the use of file encryption document. The procedure can be achieved using text files, Office documents, RAR compressed files, multimedia files and other documents of various types of encryption and decryption, the key to the same types of documents, compared with characters encryption method, the method more efficient security.
