C#实现简单的文件加密与解密方式

C#实现文件加密与解密

代码:

static class HandleFiles
 {
 public static void EncryptFile(string inputFile, string outputFile) //加密
 {
 try
 {
 string password = @"12345678";
 UnicodeEncoding UE = new UnicodeEncoding();
 byte[] key = UE.GetBytes(password);

 string cryptFile = outputFile;
 FileStream fsCrypt = new FileStream(cryptFile, FileMode.Create);

 RijndaelManaged RMCrypto = new RijndaelManaged();

 CryptoStream cs = new CryptoStream(fsCrypt,
 RMCrypto.CreateEncryptor(key, key),
 CryptoStreamMode.Write);

 FileStream fsIn = new FileStream(inputFile, FileMode.Open);

 int data;
 while ((data = fsIn.ReadByte()) != -1)
 cs.WriteByte((byte)data);


 fsIn.Close();
 cs.Close();
 fsCrypt.Close();


 MessageBox.Show("Encrypt Source file succeed!", "Msg :");
 }
 catch(Exception ex)
 {
 MessageBox.Show("Source file error!", "Error :");
 }
 }

 public static void DecryptFile(string inputFile, string outputFile) //解密
 {
 try
 {
 string password = @"12345678";
 UnicodeEncoding UE = new UnicodeEncoding();
 byte[] key = UE.GetBytes(password);

 FileStream fsCrypt = new FileStream(inputFile, FileMode.Open);

 RijndaelManaged RMCrypto = new RijndaelManaged();

 CryptoStream cs = new CryptoStream(fsCrypt,
 RMCrypto.CreateDecryptor(key, key),
 CryptoStreamMode.Read);

 FileStream fsOut = new FileStream(outputFile, FileMode.Create);

 int data;
 while ((data = cs.ReadByte()) != -1)
 fsOut.WriteByte((byte)data);

 fsOut.Close();
 cs.Close();
 fsCrypt.Close();

 MessageBox.Show("Decrypt Source file succeed!", "Msg :");

 }
 catch(Exception ex)
 {
 MessageBox.Show("Source file error", "Error :");
 }
 }
 }

C#进行url加密解密与jquery前端加密解密

当我们程序发布于服务器上会遇到前端报错。因为有特殊原因导致。

此时需要对传输的数据,进行加密,后台进行解密处理

C#进行url加密与解密

HttpUtility.UrlEncode(val);  //utf-8 编码
HttpUtility.UrlDecode(val);  //utf-8 解码
HttpUtility.UrlEncode(val, System.Text.Encoding.GetEncoding(936));  //gb2312编码
HttpUtility.UrlDecode(val, System.Text.Encoding.GetEncoding(936));  //gb2312解码
System.Web.HttpUtility.UrlEncode(val, System.Text.Encoding.GetEncoding("GB2312"));//gb2312编码
System.Web.HttpUtility.UrlDecode(val, System.Text.Encoding.GetEncoding("GB2312"));//gb2312解码

jquery

decodeURIComponent(val);//Jquery解码
encodeURIComponent(val);//Jquery编码

总结
