//ACSII码加密 private static string ACSIIPWd(string rpwd) { string Ret; byte[] array = System.Text.Encoding.ASCII.GetBytes(rpwd); byte[] byteArray = new byte[array.Length]; for (int i = 0; i < array.Length; i++) { int asciicode = (int)(array[i]); asciicode = asciicode + 1; byteArray[i] = (byte)asciicode; } System.Text.ASCIIEncoding asciiEncoding = new System.Text.ASCIIEncoding(); string strCharacter = asciiEncoding.GetString(byteArray); Ret = strCharacter; return Ret; }
//MD5加密 private static string MD5PWd(string rpwd) { string Ret; MD5 md5 = new MD5CryptoServiceProvider(); byte[] palindata = Encoding.Default.GetBytes(rpwd);//将要加密的字符串转换为字节数组 byte[] encryptdata = md5.ComputeHash(palindata);//将字符串加密后也转换为字符数组 Ret = Convert.ToBase64String(encryptdata); return Ret; }
//RSA加密 private static string RSAPWD1(string myKeyContainerName) { string ret = ""; CspParameters cp = new CspParameters(); cp.KeyContainerName = myKeyContainerName; RSACryptoServiceProvider rsa = new RSACryptoServiceProvider(cp); ret = rsa.ToXmlString(true); Console.WriteLine("Key is : \n" + rsa.ToXmlString(true)); return ret; }
//DES加密 private static string DESPWD(string ciphertext) { string desPWD = ""; byte[] buffer; DESCryptoServiceProvider DesCSP = new DESCryptoServiceProvider(); MemoryStream ms = new MemoryStream();//先创建 一个内存流 CryptoStream cryStream = new CryptoStream(ms, DesCSP.CreateEncryptor(), CryptoStreamMode.Write);//将内存流连接到加密转换流 StreamWriter sw = new StreamWriter(cryStream); sw.WriteLine(ciphertext);//将要加密的字符串写入加密转换流 sw.Close(); cryStream.Close(); buffer = ms.ToArray();//将加密后的流转换为字节数组 desPWD = Convert.ToBase64String(buffer);//将加密后的字节数组转换为字符串 return desPWD; }
