Hi,大家好,我是编程小6,很荣幸遇见你,我把这些年在开发过程中遇到的问题或想法写出来,今天说一说MD5【加密以及解密】,希望能够帮助你!!!。
using System; using System.Collections.Generic; using System.IO; using System.Security.Cryptography; using System.ServiceModel; using System.Text; namespace ConsoleTest { public class MD5解密 { // 在此处添加更多操作并使用 [OperationContract] 标记它们 #region MD5加密 /// <summary> /// MD5加密 /// </summary> /// <param name="strSource">需要加密的字符串</param> /// <returns>MD5加密后的字符串</returns> [OperationContract] public string Md5Encrypt(string strSource) { //把字符串放到byte数组中 byte[] bytIn = System.Text.Encoding.Default.GetBytes(strSource); //建立加密对象的密钥和偏移量 byte[] iv = { 102, 16, 93, 156, 78, 4, 218, 32 };//定义偏移量 byte[] key = { 55, 103, 246, 79, 36, 99, 167, 3 };//定义密钥 //实例DES加密类 DESCryptoServiceProvider mobjCryptoService = new DESCryptoServiceProvider(); mobjCryptoService.Key = iv; mobjCryptoService.IV = key; ICryptoTransform encrypto = mobjCryptoService.CreateEncryptor(); //实例MemoryStream流加密密文件 System.IO.MemoryStream ms = new System.IO.MemoryStream(); CryptoStream cs = new CryptoStream(ms, encrypto, CryptoStreamMode.Write); cs.Write(bytIn, 0, bytIn.Length); cs.FlushFinalBlock(); string strOut = System.Convert.ToBase64String(ms.ToArray()); return strOut; } #endregion #region MD5解密 /// <summary> /// MD5解密 /// </summary> /// <param name="Source">需要解密的字符串</param> /// <returns>MD5解密后的字符串</returns> [OperationContract] public string Md5Decrypt(string Source) { //将解密字符串转换成字节数组 byte[] bytIn = System.Convert.FromBase64String(Source); //给出解密的密钥和偏移量,密钥和偏移量必须与加密时的密钥和偏移量相同 byte[] iv = { 102, 16, 93, 156, 78, 4, 218, 32 };//定义偏移量 byte[] key = { 55, 103, 246, 79, 36, 99, 167, 3 };//定义密钥 DESCryptoServiceProvider mobjCryptoService = new DESCryptoServiceProvider(); mobjCryptoService.Key = iv; mobjCryptoService.IV = key; //实例流进行解密 System.IO.MemoryStream ms = new System.IO.MemoryStream(bytIn, 0, bytIn.Length); ICryptoTransform encrypto = mobjCryptoService.CreateDecryptor(); CryptoStream cs = new CryptoStream(ms, encrypto, CryptoStreamMode.Read); StreamReader strd = new StreamReader(cs, Encoding.Default); return strd.ReadToEnd(); } #endregion } }
测试:
using System; using System.Security.Cryptography; namespace ConsoleTest { class Program { static void Main(string[] args) { #region MD5解密 MD5解密 m = new MD5解密(); string md5jiami = m.Md5Encrypt("huaxiaoujia"); Console.WriteLine("加密为:" + md5jiami); string md5ecode = m.Md5Decrypt(md5jiami); Console.WriteLine("解密为:"+ md5ecode); #endregion } } }
输出结果:
