• Asp.net中URL加密和解密(转)


    下面介绍常用的加密解密方法:

    1.加密。   Response.Redirect("DetailInfo.aspx?id=" + Convert.ToBase64String(System.Text.Encoding.Default.GetBytes("sp10006")).Replace("+","%2B"));  

     2.解密。   string ID = System.Text.Encoding.Default.GetString(Convert.FromBase64String(Request.QueryString["id"].ToString().Replace("%2B","+")));

    二、DEC加密解密

    using System;
    using System.Security.Cryptography;
    using System.IO;
    using System.Text;
    namespace EIP.Framework
    {
    public class Security
    {
    string _QueryStringKey = "abcdefgh"; //URL传输参数加密
    Key string _PassWordKey = "hgfedcba"; //PassWord加密
    Key public Security() { }
    public string EncryptQueryString(string QueryString) { return Encrypt(QueryString,_QueryStringKey); } public string DecryptQueryString(string QueryString) { return Decrypt(QueryString,_QueryStringKey); } public string EncryptPassWord(string PassWord) { return Encrypt(PassWord,_PassWordKey); }
    public string DecryptPassWord(string PassWord)
    { return Decrypt(PassWord,_PassWordKey); } /// /// DEC 加密过程 /// /// /// ///
    public string Encrypt(string pToEncrypt,string sKey)
    { DESCryptoServiceProvider des = new DESCryptoServiceProvider(); //把字符串放到byte数组中
    byte[] inputByteArray = Encoding.Default.GetBytes(pToEncrypt); //
    byte[] inputByteArray=Encoding.Unicode.GetBytes(pToEncrypt);
    des.Key = ASCIIEncoding.ASCII.GetBytes(sKey); //建立加密对象的密钥和偏移量
    des.IV = ASCIIEncoding.ASCII.GetBytes(sKey); //原文使用ASCIIEncoding.ASCII方法的GetBytes方法 MemoryStream ms = new MemoryStream(); //使得输入密码必须输入英文文本
    CryptoStream cs = new CryptoStream(ms,des.CreateEncryptor(),CryptoStreamMode.Write);
    cs.Write(inputByteArray, 0, inputByteArray.Length);
    cs.FlushFinalBlock();
    StringBuilder ret = new StringBuilder();
    foreach(byte b in ms.ToArray()) { ret.AppendFormat("{0:X2}", b); }
    ret.ToString(); return ret.ToString(); } /// /// DEC 解密过程 /// /// /// ///
    public string Decrypt(string pToDecrypt, string sKey)
    { DESCryptoServiceProvider des = new DESCryptoServiceProvider();
    byte[] inputByteArray = new byte[pToDecrypt.Length / 2];
    for(int x = 0; x < pToDecrypt.Length / 2; x++)
    { int i = (Convert.ToInt32(pToDecrypt.Substring(x * 2, 2), 16));
    inputByteArray[x] = (byte)i; }
    des.Key = ASCIIEncoding.ASCII.GetBytes(sKey); //建立加密对象的密钥和偏移量,此值重要,不能修改 des.IV = ASCIIEncoding.ASCII.GetBytes(sKey);
    MemoryStream ms = new MemoryStream();
    CryptoStream cs = new CryptoStream(ms, des.CreateDecryptor(),CryptoStreamMode.Write);
    cs.Write(inputByteArray, 0, inputByteArray.Length);
    cs.FlushFinalBlock(); StringBuilder ret = new StringBuilder(); //建立StringBuild对象,CreateDecrypt使用的是流对象,必须把解密后的文本变成流对象
    return System.Text.Encoding.Default.GetString(ms.ToArray()); } /// /// 检查己加密的字符串是否与原文相同 /// /// /// /// ///
    public bool ValidateString(string EnString, string FoString, int Mode)
    {
    switch (Mode)
    { default: case 1: if (Decrypt(EnString,_QueryStringKey) == FoString.ToString()) { return true; } else { return false; } case 2: if (Decrypt(EnString,_PassWordKey) == FoString.ToString()) { return true; } else { return false; } } } } } 类中URL及帐号加密使用了不同的KEY。
    

    调用URL加密过程如下: EIP.Framework.Security objSecurity = new EIP.Framework.Security(); objSecurity.EncryptQueryString(''待加密的字符串'');

    解密:objSecurity.DecryptQueryString(''传递过来的参数);
