asp.net中实现MD5加密、解密的方法
这个MD5加密、解密的方法会使用即可。
使用时的代码备忘:Response.Write(FormsAuthentication.HashPasswordForStoringInConfigFile("要加密的字符串", "MD5"));
以下是加密、解密的代码部分:
/*用法 protected void Page_Load(object sender, EventArgs e) { //加密 this.Title = CEncrypt.DesEncrypt("pwd", CEncrypt.Key); this.Title += CEncrypt.DesDecrypt(this.Title, CEncrypt.Key); Response.Write(CEncrypt.DesDecrypt("gAYyhdLQunc=", CEncrypt.Key)); } */ using System; using System.IO; using System.Text; using System.Security.Cryptography; using System.Web; namespace YD.Common { /// <summary> /// 加密码类 /// </summary> public class CEncrypt { /// <summary> /// 加密 /// </summary> /// <param name="inputString"></param> /// <returns></returns> public static string DesEncrypt(string inputString) { return DesEncrypt(inputString, Key); } /// <summary> /// 解密 /// </summary> /// <param name="inputString"></param> /// <returns></returns> public static string DesDecrypt(string inputString) { return DesDecrypt(inputString, Key); } /// <summary> /// 密匙 /// </summary> private static string Key { get { return "hongye10"; } } /// <summary> /// 加密字符串 /// 注意:密钥必须为8位 /// </summary> /// <param name="strText">字符串</param> /// <param name="encryptKey">密钥</param> /// <param name="encryptKey">返回加密后的字符串</param> public static string DesEncrypt(string inputString, string encryptKey) { byte[] byKey = null; byte[] IV = { 0x12, 0x34, 0x56, 0x78, 0x90, 0xAB, 0xCD, 0xEF }; try { byKey = System.Text.Encoding.UTF8.GetBytes(encryptKey.Substring(0, 8)); DESCryptoServiceProvider des = new DESCryptoServiceProvider(); byte[] inputByteArray = Encoding.UTF8.GetBytes(inputString); MemoryStream ms = new MemoryStream(); CryptoStream cs = new CryptoStream(ms, des.CreateEncryptor(byKey, IV), CryptoStreamMode.Write); cs.Write(inputByteArray, 0, inputByteArray.Length); cs.FlushFinalBlock(); return Convert.ToBase64String(ms.ToArray()); } catch (System.Exception error) { //return error.Message; return null; } } /// <summary> /// 解密字符串 /// </summary> /// <param name="this.inputString">加了密的字符串</param> /// <param name="decryptKey">密钥</param> /// <param name="decryptKey">返回解密后的字符串</param> public static string DesDecrypt(string inputString, string decryptKey) { byte[] byKey = null; byte[] IV = { 0x12, 0x34, 0x56, 0x78, 0x90, 0xAB, 0xCD, 0xEF }; byte[] inputByteArray = new Byte[inputString.Length]; try { byKey = System.Text.Encoding.UTF8.GetBytes(decryptKey.Substring(0, 8)); DESCryptoServiceProvider des = new DESCryptoServiceProvider(); inputByteArray = Convert.FromBase64String(inputString); MemoryStream ms = new MemoryStream(); CryptoStream cs = new CryptoStream(ms, des.CreateDecryptor(byKey, IV), CryptoStreamMode.Write); cs.Write(inputByteArray, 0, inputByteArray.Length); cs.FlushFinalBlock(); System.Text.Encoding encoding = new System.Text.UTF8Encoding(); return encoding.GetString(ms.ToArray()); } catch (System.Exception error) { //return error.Message; return null; } } } }
