文件加密问题。 [英] Problem with file encryption.

问题描述

在我的程序中，我使用Triple DES算法加密和解密.dat文件。它加密但是desination文件中的所有字符都替换为这些字符：�$？ï/ <％



这是代码：

in my program, I am encrypting and decrypting a .dat file using the Triple DES algorithm. It encrypts but all the characters in the desination file are replaced with these characters: �$
ï/‹%

Here's the code:

public byte[] Transform(byte[] input, ICryptoTransform CryptoTransform)
       {
           // create the necessary streams
           MemoryStream memStream = new MemoryStream();
           CryptoStream cryptStream = new CryptoStream(memStream, CryptoTransform, CryptoStreamMode.Write);

           // transform the bytes as requested
           cryptStream.Write(input, 0, input.Length);
           cryptStream.FlushFinalBlock();

           // Read the memory stream and
           // convert it back into byte array
           memStream.Position = 0;
           byte[] result = memStream.ToArray();

           // close and release the streams
           memStream.Close();
           cryptStream.Close();

           // hand back the encrypted buffer
           return result;
       }

以下是代码：

Here's the code:

public byte[] Transform(byte[] input, ICryptoTransform CryptoTransform)
       {
           // create the necessary streams
           MemoryStream memStream = new MemoryStream();
           CryptoStream cryptStream = new CryptoStream(memStream, CryptoTransform, CryptoStreamMode.Write);

           // transform the bytes as requested
           cryptStream.Write(input, 0, input.Length);
           cryptStream.FlushFinalBlock();

           // Read the memory stream and
           // convert it back into byte array
           memStream.Position = 0;
           byte[] result = memStream.ToArray();

           // close and release the streams
           memStream.Close();
           cryptStream.Close();

           // hand back the encrypted buffer
           return result;
       }

您期望加密做什么？将其更改为这是加密数据的文本？





加密数据不具有可读性：这就是整体理念。当你使用Triple DES时，它返回一个加密的字节数组......因为它应该是。

What did you expect encryption to do? Change it to text which says "This is encrypted data."?


Encrypted data is not meant to be readable: that's the whole idea. When you use Triple DES it returns an array of bytes which are encrypted...because it is supposed to.
