本文主要是介绍url加密传输C#，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！
通常我们在做系统的时候,要对参数加密处理再通过url传过去,根椐许多朋友对url安生性问题的解决，这是我常用到的加密方法如下。
能保证密码的安生性。
Des 加密 GB2312 :
/// <summary>
/// If don't input key , Use default key
/// </summary>
/// <param name="str"></param>
/// <returns></returns>
public static string Encode(string str)
{
return Encode(str, "Rainight");
}
/// <summary>
/// Des 加密 GB2312
/// </summary>
/// <param name="str"></param>
/// <param name="key"></param>
/// <returns></returns>
public static string Encode(string str, string key)
{
DESCryptoServiceProvider provider = new DESCryptoServiceProvider();
provider.Key = Encoding.ASCII.GetBytes(key.Substring(0, 8));
provider.IV = Encoding.ASCII.GetBytes(key.Substring(0, 8));
byte[] bytes = Encoding.GetEncoding("GB2312").GetBytes(str);
MemoryStream stream = new MemoryStream();
CryptoStream stream2 = new CryptoStream(stream, provider.CreateEncryptor(), CryptoStreamMode.Write);
stream2.Write(bytes, 0, bytes.Length);
stream2.FlushFinalBlock();
StringBuilder builder = new StringBuilder();
foreach (byte num in stream.ToArray())
{
builder.AppendFormat("{0:X2}", num);
}
stream.Close();
return builder.ToString();
}
Des 解密 GB2312 :
/// <summary>
/// if don't input key , Use default key
/// </summary>
/// <param name="str">Desc string </param>
/// <returns></returns>
public static string Decode(string str)
{
return Decode(str, "Rainight");
}
/// <summary>
/// Des 解密 GB2312
/// </summary>
/// <param name="str">Desc string</param>
/// <param name="key">Key ,必须为8位 </param>
/// <returns></returns>
public static string Decode(string str, string key)
{
DESCryptoServiceProvider provider = new DESCryptoServiceProvider();
provider.Key = Encoding.ASCII.GetBytes(key.Substring(0, 8));
provider.IV = Encoding.ASCII.GetBytes(key.Substring(0, 8));
byte[] buffer = new byte[str.Length / 2];
for (int i = 0; i < (str.Length / 2); i++)
{
int num2 = Convert.ToInt32(str.Substring(i * 2, 2), 0x10);
buffer[i] = (byte) num2;
}
MemoryStream stream = new MemoryStream();
CryptoStream stream2 = new CryptoStream(stream, provider.CreateDecryptor(), CryptoStreamMode.Write);
stream2.Write(buffer, 0, buffer.Length);
stream2.FlushFinalBlock();
stream.Close();
return Encoding.GetEncoding("GB2312").GetString(stream.ToArray());
}
加密之后url如:

paras是我们加密的参数。
ran 为一个随机 数，确保每次都不读缓存的
ran要以等于这个
function RefreshNumber() {
var d = new Date();
return d.valueOf();
}
这篇关于url加密传输C#的文章就介绍到这儿，希望我们推荐的文章对编程师们有所帮助！
