Encrypt Text Using TripleDESCryptoServiceProvider In C#

This snippet uses the TripleDESCryptoServiceProvider Class to encrypt a string and save it to a text file. The key to decrypt the file is also saved into a seperate text file.

1. using System;
2. using System.IO;
3. using System.Security.Cryptography;
5. public class Encrypt
6. {
7.     public static void Main()
8.     {
10.         FileStream fStream = File.Create(@"C:\text.txt");
12.         TripleDESCryptoServiceProvider tdes = new TripleDESCryptoServiceProvider();
14.         CryptoStream cStream = new CryptoStream(fStream, tdes.CreateEncryptor(), CryptoStreamMode.Write);
16.         StreamWriter sWriter = new StreamWriter(cStream);
19.         sWriter.WriteLine("Please encrypt me.");
20.         sWriter.Flush();
21.         sWriter.Close();
23.         FileStream fStreamKey = File.Create(@"C:\key.key");
24.        
25.         BinaryWriter bWriter = new BinaryWriter(fStreamKey);
27.         bWriter.Write( tdes.Key );
28.         bWriter.Write( tdes.IV );
30.         bWriter.Flush();
31.         bWriter.Close();
33.     }
35. }
